Why are the flames on my range yellow?

Last week I noticed that the flames on my LG gas range were more yellow than blue. Normally the flames are completely blue and clean-burning, so this concerned me. After a few phone calls, a utilities service visit and a bit of Google searching, I finally discovered the unexpected problem.

The concern

My main concern with the orange flames is that it indicates that the natural gas is not burning cleanly. My initial guess was that there was an improper gas-to-air ratio. I checked each of the elements, but all of them were seated properly and all of them had a bright orange flame.

The stove still seemed to cook things just fine, and I actually noticed that after about 20 minutes of cooking the flames went back to a more blue hue. However, a few hours later, when I needed to cook again, they would be yellow again.

I even called my local utilities company to report the problem and they sent out a serviceman. He had never seen anything like this before, and was concerned because yellow flames could indicate higher levels of carbon monoxide. The serviceman suggested that I call the stove manufacturer to have the regulator replaced.

The solution

Just before gathering my warranty card and purchase receipts in order to call LG tech support, I decided to do a final Google search to see if there were any answers online. During my search, I found this video and immediately my jaw dropped.

A HUMIDIFIER! That was the cause. A small children’s humidifier on the 2nd floor in my house. My daughter had been congested with a head cold and we had put a humidifier in her bedroom upstairs. After the humidifier had been running for a few hours, the humid air had apparently made its way downstairs and was now affecting the flames on my gas range.

To test the theory that the humidifier was affecting the colour of my gas flames, I turned off the humidifier for a few hours. Sure enough, my flames went back to blue. Then I plugged in the humidifier next to the gas range and turned it back on. Almost immediately, the flames turned to bright orange! (See my pictures below)

I would have never believed this if I didn’t experience it myself, but having a humidifier in your house can definitely affect the colour of your flames on a natural gas stove.

Same problem, flames turned very yellow on my natural gas range, my hot water heater, and my furnace. I took the humidifier out of the bedroom and now the flames appear less yellow, I will see what happends in a few days, if they get back to all blue. It is also very humid outside and has been for about 2 weeks in St. Louis area. Windows in our house have been wet in the mornings. But it is still humid and the removal of the humidifier has certainly helped thus far. I had GE Appliance serviceman out and he checked the pressures on the Gas Range and all was normal. He checked the furnace and hot water heater and determined it was a Gas Company issue. Gas Company “never heard of such a thing,” I am cancelling that appointment thanks to this e-mail string.

I’ve had an orange flame for three days now. After reading this post, I realized…three days ago I started my SMALL humidifier in my upstairs bedroom! 🙂 Thanks Chris!!

I too had same problem immediately after installing a humidifier approximately 15 feet from my gas range. Called VA gas and they had no solution and stated not to use with yellow/ornage flame. Called whirlpool and they again had no solution. Finally called Pureguardian and they explained that it was the water being used. Mine is city water and haven’t seen any indication that it was hard. She also explained that flame color is caused by particles in the air from the water, i.e., minerals, salt, etc. It causes no harm but suggested using distilled water to see if makes a difference.

Thank you! I have and this issue on and off for the past month, I have been running a humidifier in a upstairs bedroom as well. I noticed the orange flame about a month ago, then it would go away and come back. Right now it’s humid outside and with running the humidifier the orange flame is back and staying but now I know why!

Had the exact same thing happen. A small one room humidifier ran in a bedroom caused my stove to have the orange flames. It also turned the gas flames used in my fireplace to be completely orange vs blue and orange.

Thank you! My problem is solved. I was so glad to fine this since I was having the same thing happen when using my small humidifier.

Holy cow! I called LG and almost got someone to come out to check on the orange flame problem. I decided to put it off so that I can search on the Internet. After I read your blog, I turned off all the ultrasonic humidifiers in the house. That was about 2:30PM.The orange flame problem didn’t disappear immediately. After I got home from work around 6PM, there were no more orange flames!!!

One more grateful reader! Do you know if the flame’s being orange under these circumstances indicate a problem? Or is everything OK and can I keep using my humidifier?

This is VERY HELPFUL !!! I’ve been working on steam boilers for 30 years and my first approach to this problem ( started yesterday ,after a drizzle here in the desert , the burner flame started to turn orange. From the technical point of view … this is incomplete combustion or something other
than the fuel ( natural gas ) is burning ( like dirt , cooking oil , food stuffs ) . After cleaning every thing along the path ( with soft wire brushes ) , still there is orange-blue flame. Shut-off the AC system and run the fan only ( luckily the outside temp. is only 95 not 110F at this time of the year in the desert ). Open all windows and doors ( including the garage door ) for an hour. The flame turn to all blue again…… proving that there is little amount of oxygen in the combustion process.
The CO and CO2 alarms are quite …… checked the battery and system … everything is OK.
Last night we had a good rainfall ….( have to turn off the automatic irrigation system at least for today and perhaps tomorrow ). This morning the flame is again a mixture of orange and blue for all the burners. THANK YOU VERY MUCH for everybody for your postings …. now I know why. We’ve been using the room humidifiers ( four of them ) for almost 9 months and the flame is OK until yesterday and today and maybe tomorrow until the humidity outside is back to below 10 % ).
The humidity near the cooling range is 80% !!!!! Can’t shutdown the humidifier for some medical reason!!!!!!!

Thank you so much. I’m glad I kept on searching on google to find your answer. Saved me $ and time trying to figure this out. My gas burner started turning yellow the next day after using my humidifier.

I am so glad I checked your post. I too just noticed yellow flames where they’ve always been blue. I was getting ready to get out the manual, take apart the burners, and contemplate calling the gas co with the same fears mentioned. Decided to google first. Guess what, I developed laryngitis las week, found my old humidifier and set it up in the bedroom. Would never have thought that was the problem!

Very glad I found this! I was cleaning the carpet in the room next to the kitchen and my wife noticed the flames on two burners on the gas stove were not as blue as normal. She thought we might have air in the line and I was about to open the top of the stove to see if there was a way to adjust the air to the burner when I paused to check the internet and found this. The moisture in the air from the carpet cleaning apparently caused the increased yellow in the flame. Thanks!

Discovered the same problem today with ultrasonic humidifier. Most likely the problem is sodium in the softened water being used. Bet this won’t happen if you use distilled water.

We just purchased an ultrasonic humidifier & noticed the flames turned yellow. We noticed, as others did, that when we turned it off, the flames eventually went back to blue. We do not have a water softener, but I will try the distilled water…hopes it works! The humidity monitor I purchased shows the humidity to be perfectly normal right now so I don’t have it on…and the flames are blue! So happy to find this post…saved me some time, trouble & expense!

Thank you so much! I had actually called the gas company to come out and look. That morning, I turned off our humidifier and by the time they got here, the flames were blue. We turned it back on for bedtime and sure enough the flames were orange again. We thought the gas company was playing a cruel joke but it was definitely our humidifier. Whew!

Does anyone know if having orange flames is actually harmful in any way? It doesn’t seem like it but I thought I’d ask.

I noticed orange flames a couple of nights ago while cooking burger on the stove, medium flame. I set the timer for 3 min after flipping the burger once, and before the timer went off, a very loud pop like a gunshot went off. The cover for the handle weld on the inside of the pan had exploded off! What a scare! It may be coincidence, but I think yellow flames could burn hotter.

By the way, what happens if you turn your humidifier off for a decent length of time and the problem persists? My vaporizer has been off 5 hours, without an appreciable change in the flame color. Any suggestions for tomorrow morning, when it will be about 16 hours sans humidifier, if the flames are still orange?

It’s been about 18 hours since turning off my vaporizer and the flames are back to blue. This occurrence seems bizarre, but I can’t assign the yellow flames to any other cause. I’ll let you know if it happens again, and I’m NOT using the vaporizer. BTW, I had the gas guy out the day after I noticed it–no help at all. Thanks, Chris!

Thanks for this info, Chris We live in a condo and I was concerned. PSEG came and said it was caused by cleaning products or “debris” in the line No help from him. We didn’t use the humidifier that night and flame was back to blue next morning. Are there any health problems connected to orange flames? Also we have used the humidifier for years and never had this before this week. Do I have to do anything to solve this problem?

This will cause a problem with your furnace,mine burns LP gas and is so sooted up it may be ruined.Once the secondary heat exchanger in a high efficiency furnace
is plugged with soot it cant be fixed.I am an hvac contractor,and we see this from time to time but never realized it was an ultrasonic humidifier that caused the problem.I just discovered this in my own house since we stated using one.

Hi Owen, just wondering if you are certain the humidifier/orange flames caused the soot ruining your furnace? Not doubting. Just wondering. The chemist types who have posted and commented about this say it is the chemicals from the mist burning which cause a yellow color (sodium probably), not incomplete combustion. If ultrasonic humidifiers ruin gas furnaces then a lot of folks out there are replacing furnaces. Wow!

Thank you for the info. We just got an ultrasonic humidifier about a week ago, and I had noticed once burner burning orange, but tonight I noticed they are all affected (I had not been using the stove for a few days.)

Whew! I turned on humidifier last night in the upstairs bedroom, and today morning noticed the orange flames. I have a GE range and read the manual about gas-to-air ratio. Decided to look online for similar problem before I called the guy who installed range. Glad I googled first. Thanks man, you just saved me some dough,

Gee, this is almost fun. I have a terrible cold and bought a humidifier last night. When I went to turn on water for coffee this morning I noticed the orange flame…then noticed it on my gas fireplace and figured something was up with the gas company deliverance. Got online…googled “why are my gas stove flames orange?” and got this. Thanks for the peace of mind. Way cool.

Thank you for this post! This happened to me to! I wonder what’s the chemical reaction that causes the flames to burn orange? I also put a purifying tablet into my humidifier. Do you think the chemicals that purify the water can cause this? Or is it just the extra moisture.

Thanks Chris. I have this problem and use an ultrasonic humidifier. Do you know if other humidifiers, for example, the ones that I have a heating element, also cause this problem?

I would imagine that any humidifier would act the same way, as it is putting more moisture in the air. But I’m certainly not an expert on this topic, so I don’t know for sure.

Try putting distilled water in the humifier. I still think the issue is the sodium in the water from the water being softened either by the homeowner or the water company.

I had this problem and I used ordinary tap water in an area where the water tends to be hard, so softener is not the difference.

It’s not the moisture making the flames blue. It is the mineral content in the water being put into the air. Water has minerals in it, when it is defused into the air via myst the minerals will travel all around the home. The orange flame you are seeing is the minerals being burned. To make the flame less orange use a distilled or filtered water.

Thx very much, was cooking on stove and flame turned yellow…wife was cleaning iron, creating a lot of steam…and I have seen this other times and it would disappear and I would wonder why…now I know….Now I’m curious that if we buy distilled water and use that in her iron if the flame would still turn yellow…..because we do use a water softener and she uses tap water in her iron….

I need to know same question. Plus why does extra moisture cause this to happen? When I cook (soup & such) which causes moisture, it doesn’t do that.

I just had the same problem. This saved me a lot of trouble, I was concerned I had a gas leak. Thanks. I would suggest opening a window in kitchen while cooking if burners are going to be on a long time carbon dioxide is being produced when the flame is orange.

I just discovered the same thing. Interesting since I had 2 humidifiers running in my house. The air here is very dry and everything metal was shocking me therefore started up the humidifiers.
Now not sure what to do since we need the humidity.

Follow what Al says, use distilled water in your humidifiers. Chris discovered the Cause But Al found the reason.

If humidity is the Reason, then people who live in the tropics, where humidity can go as high as 90%, will perennially have yellow flames on their range cookers. Al is Right, it is most likely the added minerals in the air from the tap water in your humidifier.

By the way if this Really Works, write to me ( and let me know for I have been drinking distilled water for over 3 decades AND Never took a day of Sick Leave for the same period working.

Ps: No, I do not sell distillers nor anything for that matter. Just want to share experiences, that’s all.

Great information. Thank you! My range flames went from blue to blue-yellow about 3 weeks ago. I was concerned and thought of calling the gas company until I read your post. I bought a humidifier about 3 weeks ago. Now it all makes sense.

Stumbled upon your Blog – b.c. of this post – wow! Never would have thought a humidifier was causing the change – we have the old-time gas stove heaters in our bathrooms and they were so orange it was a spectacular sight…thanks again

THIS is a big problem,my high efficiency lp gas furnace may be ruined do to poor combustion,the exhaust pipe is black and the condensate trap was plugged with soot.An orange flame is indicative of poor combustion ,this may not bother too much on the stove but the furnace is a different matter.

Noticed the problem with a ventless gas fireplace that always had blue flames. The pilot turned orange and when fully on, all flames were bright orange. Had just turned on humidifier for daughter with croup. Thanks for saving me an expensive service call.

OMG! You solved my problem completely. We just started using an oil diffuser – a small container that puts out a nice smelling mist after you put water and an essential oil in it. Sure enough – that mist caused all the burners to have that awful orange flame. Turned off the mister and everything back to blue. YEAH! Makes me want to celebrate. Thank You.

Thanks so much. I wondered if that we’re the cause because I just got the humidifier yesterday and had never seen an orange flame on the stove until now. Glad I found your post! Thanks for taking the time!

Ive used humidifiers during heating season for years and just recently got a new one and that was around the time this started. Thanks for putting my mind at rest

Wow thanks a lot, that’s the exact same problem we had. We were running a humidifier all night and in the morning we noticed the same yellow flames. Also today it was raining outside as opposed to sunny for the last week. Thanks


Thanks so much! The last time this happened we had to put in a new wall heater. This time i knew it had to be another cause. Reading your explanation saved me from calling the gas company who would have red-tagged the stove and heater – if like other gas companies they didn’t know that the cause of the yellow flame was simply humidity.

I know,right? It was so easy for a quasi-luddite like me to find this solution, can you really believe that gas companies don’t know this? C’mon!

Very happy that I decided to do a quick check thru Google to see what the problem was with my yellow/orange flames all of a sudden. You saved me a huge service bill! Thank you, Thank you!!
I turned on a humidifier this morning, but before doing so the flames were blue. Late this afternoon
I notice the flames had changed color. Such a simple fix.

You just saved me A LOT of money and headache on a technician, I’m sure of it! Our gas company just left, scratching his head and suggested I call a service company. Thank you for sharing!

Just bought a humidifier and used filtered water (from a water softener). Next day the flames were yellow/orange. Saw this web site and turned off the humidifier and waited for a few hours and the flames were back to blue. Went out and bought distilled water. Used the humidifier and no problems now. I’m spreading the word! THANKS

Holy @!$@ Batman …Wow … i just googled this and yes I recently started using a humidifier. Thank you for the accurate answer!!

Thank you for your post. I got a splash of water on my frying pan. Then, a few moments later, I had orange flames. Now I’m glad I know why and that I have nothing to worry about.

Thank you for your post. Yep I experience the same yellow flames, I need to do some testing to understand better since it doesn’t make sense to me because when it rains for days non stop the humidity level is very high (more than what a humidifier can put out), so that should cause yellow flame but it never did. So I find it hard to blame the humidity as the cause, possibly the ionic concentration from humidifier is the culprit (need to do some testing). Now I wonder how good it is to breath this ionic air from humidifier!

Big question: Is it dangerous? I have a small humidifier in my downstairs rec room. When I run it, it causes the flames in my gas fireplace to turn yellow. I don’t care about the color, but I would like to know if it is safe (my sense is that it is safe).

Orange flames aren’t particularly dangerous.

Of course, as with any fuel-burning appliance, you should always have a carbon monoxide (CO) detector in your house, but this has nothing to do with humidifiers or orange flames.

Exactly what I was thinking! I suspected that the humidifier was the culprit, and found this post, but haven’t found anything saying whether or not I should be concerned!

LOL I learned about this is our horribly insulated kitchen that’s like standing outside with a roof basically,and it started raining and all of the sudden my flame on the range went mostly orange and I panicked and tested them all and they were all that way,and I had to finish cooking,so I went through,near the end it returned to like 70 blue 30 orange. Well,after some research,I saw a few people with the humidifier conclusion,so I went and tested the range and it was solid blue. What had happened to me was the flame went orange literally when it started raining outside,and as the rain got better so did the blue return. And testing it later when the rain stopped,it was normal.

I’ve had the same stove and lived in the same location since 2009 and today is the first time I’ve noticed that on all 4 burners the flames are partially yellow. (The ratio is more blue than yellow on all four). But that’s where the similarity stops. We do not have and have never used a humidifier. We also do not use essential oils or diffusers (sp?), nor were we doing anything that we’ve not done in the past with the stove on. Could there be other causes/reasons?

Had a boiling pan of water near the stove for about 30 minutes on and off today (allot of steam) and noticed my burners went orange/yellow, went online and found this answer, glad I did too as I was expecting a problem.phewwww.

I don’t think that distilled water is the answer. I used distilled water for about a month and ended up with my ultrasonic humidifiers clogged with mold and slime. Manufacturer said not to use distilled water, but didn’t give a reason. Now I know the reason! Big mess, and took lots of cleaning to get all of the mold removed. I have such hard water that I’ve started useing 2/3 tank of distilled + 8 drops of Clorox per gallon of distilled water, then top off the tank with tap water. (Plain tap water in the humidifiers leave a thick dust of minerals all over my furniture and floors.) So far, that mixture is working well, but still have orange flames on my cooktop.

Wow, thank you! I recently replaced my gas range with a new LG model in the spring. It has worked perfectly since installation and I had no concerns up until recently. With the summer on it’s way out and fall/winter approaching it was time to turn on the humidifier again. A few weeks ago I noticed my range’s flames were quite yellow where they used to be bright blue. A few times the flame would be bright blue, but later in the evening they would revert back to orange. This was puzzling to me and I was concerned that I would need to have to replace the range! As usual I turned to Google for help, and wouldn’t you know it? Your post was the first one that turned up. After reading your post, it dawned on me that two weeks ago I purchased a new “cool mist” humidifier! On the days I would come home from work and the humidifier was shut off because it ran dry, the range’s flame was a bright blue. However, after it was refilled and running again for a few hours, the flame went back to orange.
Thank you for sharing your knowledge with this problem. It saved me a lot of time, and undoubtedly a lot of money for nothing too!

Thanks! Had the same problem and we have a new humidifier upstairs for our daughter. Never would have put this together…

Wow thanks.. just had service and wondered why flame on air ducted hot air unit was burning yellow and found this… Turning diffuser of now and going to check to see when it turns blue hopefully.

Thank you, thank you, thank you!! We just bought 3 ultrasonic humidifiers filled them and plugged them in… and noticed ventless LP heater and LP stove flames suddenly turned orange! Thought we had propane issue called our propane company they sent out service tech… He said he’s never seen anything like this before and didn’t have any idea for the cause. Now I can tell him why!

OMG! I can’t believe my furnace of 22 yrs started acting up and I had it replaced, that is when I seen the yellow flames with LPG in the furnace, water heater and gas fireplace, I knew it was not right, after the furnace tech and I checked and cleaned the fresh air feed and inspected the flue from the roof and had the propane company replace the tank and regulators the flames were still yellow unless a couple of windows were left open, (not good with temp in single digits) furnace tech and gas company tech both said the cause was a lack of oxygen, I was afraid to go to sleep at night! 3 weeks later with intermittent yellow flames and replacing furnace filter and thinking my cat was using up all of the oxygen I thought maybe it was the ultrasonic humidifier I bought a few weeks before furnace started acting up, checked on the internet and found this, what a relief!!! Somebody needs to spread the word to furnace and gas techs! THANK YOU for the posts!

Wow, thanks everyone. Due to colds we had started 2 humidifiers in our home. Thanks to your answers we didn’t try tearing apart our stove or make an expensive service call.

I ran my humidifier and the flame on my gas stove turned orange. Wondering if the orange flame is caused by the minerals from the hard water I put in the humidifier. I wonder if the minerals from the moisture will change to color of the flame. Our water is very hard. I’ll try distilled water to see if it makes a difference.

I called a repairman for this exact problem and that is what he told me! Right now I am hearing soup for my sick child and the humidifier is running in her room upstairs…my flame is orange!!! So glad it’s nothing to worry about!

Yep I put a humidifier recently in my appt. And was wondering why my flames turn BRIGHT yellow. I thought it was my gas well having problems. Thanks for posting and letting others the apparent diagnosis!!

See Owen’s replies above, dated January 22, 2017. He is a HVAC contractor who says this will ruin your high efficiency furnace. I do not know, but “someone” should be checking on this! Furnace manufacturers, humidifier manufacturers???

OMG..this is so true. I immediately checked online when my gas flame turned orange and found this article. I actually started humidifier in morning and then after an hour this happened.I turned off humidifier and after an hour again I checked my gas flames and amazingly it turned blue normal flames. Thanks a lot Chris..You are a saviour. Stay blessed..

I was using baking powder in my closet, when I came out of my bedroom, in the dining room, the gas stove was burning with pure yellow flames!

Excellent post – very helpful. After reading thru all the comments though, I was surprised nobody was concerned about breathing in whatever the humidifier is emitting that’s causing the orange flame. If it is indeed just minerals, is that safe to be inhaling? Granted we’re drinking these same minerals, but that’s not entering our respiratory system. All I can say is that I’ve been using warm mist humidifiers for many years & never had this issue. They boil off the water, leaving all the minerals behind. Personally, I’d rather deal with having to clean the mineral deposits from the humidifier’s base, rather than breathing them in all the time. Any thoughts?

After reading this article in researching why we had yellow flames on our propane gas range, our essential oil diffuser in our kitchen was putting out enough humidity to change the flame color. We turned it off & everything was normal the next morning. Moved it to another part of the house & it affected it again! Turned it off, back to normal.
Guess I won’t be using my diffuser when the house is closed up.

I wonder if anyone has calculated what the perfect humidity level would be for health and achieving blue flames! In the Northeast, a humidifier is essential to winter survival. And from my reading, 45% is a good number. But yes, our gas range flames have turned yellow. And it takes FOREVER to boil water. Is this my cold weather tradeoff? Oy.

Followup: We had two humidifiers going in two bedrooms. The atomizing mist style and a standard evaporative model. I turned off the former and left on the latter. Waited 2 or 3 hours. The range flames returned to blue. So “evaporative” is not a culprit, apparently.
So now, two questions:
1. If the minerals change the color of a flame, what do they do to our lungs?
2. If the flames do change to orange/yellow due to this cause, is the temperature of the flame reduced as with an airflow problem?

Thank you for this information; we were puzzled because a few hours ago at dinner time everything was fine. We started using a small humidifier a couple days ago because of dry sinuses but it rarely ran all day. Today it had run for about 4 hours straight in the room. I was concerned about carbon monoxide until seeing your post.

Never imagined that this would be the cause of our yellow flame….did the experiment 3-4 times over a few day period.

I have to say, humidifier off, blue flame. Humidifier on, yellow flame!

Many thanks for the info!

This is so cool! Thank you for sharing. I have a new gas stove and was worried when I saw yellow flames. Thank you for saving me from added expense and inconvenience. It is so wonderful to be able to connect this way, helping each other solve problems that come up. What a blessing!

Glad to see I’m not crazy – put a new ultrasonic humidifier next to my gas fireplace where my congested cat sleeps. Flames turned orange and much higher – scary. But I still wonder if it’s safe and if, as some have posted, it will ruin my fireplace. Any new news?

Thank you for pistpos. I have the same brand. It happened to me too. This morning the flame was orange. Ameren staffs came this afternoon to check and claimed everything was good. Flame is actually blue now in the afternoon.

This is important info if you have a Samsung gas range with orange burner flames using natural (city) gas.
My Samsung gas range was installed this summer and had a nice blue flame. It replaced an electric range.
When I was away on vacation in early November the weather turned cold, the furnace turned on and my son started using the cool vapor humidifier with tap water. When I came home I saw the orange flame and was worried something major went wrong. After days of looking for a solution I was going to call the gas company or a technician. Then Google turned up this blog. Thanks!!
I will continue to use the humidifier and not worry about the odd color. It’s that or dry, scratchy skin.
I am adding search words below so future searches find it.
Samsung Gas Range orange flame. Yellow flame.
Samsung Gas Stove.

I have a diffuser with essential oils that I just started using in the kitchen… coincidentally the burner flames were also turning orange.. did some looking into and I saw the humidifier issue… turned off the diffuser and flames are almost completely blue.

Thank you, Chris! Our LP range all of a sudden started burning orange. Our home is all wood inside so we run a humidifier most of the winter. Yesterday, for the first time, I put 5 drops of bleach in the water reservoir as I had noticed some orange residue in the humidifier well. I thought I’d try a tiny amount to see if it helped prevent the residue without being harmful to us. This morning, orange flames from every burner for the first time. The interesting part is that our sole source of water is purified (UV light) rainwater. No chemicals. I had not had any problems with the range until I added that small amount of bleach to the rainwater. Fascinating. Thanks again!

Thank you Chris!! I was getting ready to take the stove apart and adjust the gas air mixture. I turned off the humidifier and all the burners are burning blue. Saved me a lot of time.

I boiled baking soda in water to clean a pot. The flame under the pot was bright yellow. Checked the 3 others and the same bright yellow.
2 hours later, I checked the flames and they were totally normal.

Yes you are correct i am a gas tech and i discovered this myself from experience . the other one is red tips they claim not enough air but on fixed air shutters not clogged that theory dont add up but running out of gas with a old old tank with the seperated oils in propane from its hydrocatbon state i believe cause this red flame tips in some cases but there is not much info on it. Again some things you learn as you go.

I had exactly the same issue. Called out the stove guy he didn’t know what the problem was. Called out the gas guy and he said humidity! And it was only over that past week that we had switched on the upstairs humidifiers. Turned them off, gas was blue again! Then I googled it and this article came straight up.

We noticed the orange flame, pulled the stove out- no small task- cleaned everything with orange flame continuing. Thought we would be buying a new stove- the clock feature is non functional- could deal with it but not possible carbon monoxide poisoning…
Two new humidifiers had been running…
Read your blog- shut off the humidifiers and blue flame back this morning! Am not getting a new stove now! Thank you
