oven range gas smell

I have a ~2 year old KitchenAid gas range Model # KGRS205TSS0. In the past day or two, we have noticed a partially combusted gas smell when we use the oven. The burners seem unaffected but might have a bit more flame that is harder to tell with the burners. Today we unscrewed the panel inside the oven to see what the flame looked like. We noticed that the flame was bigger (yellow tips, blowing and lifting of the flame) than the installation manual specified so we attempted to adjust the oven bake burner by turning the air shutter adjustment screw. We tried the screw in even position and were not able to adjust the flame to a lower position (although we could adjust it bigger). We've called the gas company and they indicated that there are no known issues with gas pressure and our other gas appliances seem to be operating fine. Further, the gas smell is only present when the oven is on so I don't think we have a gas piping leak. I'm confident in saying this problem is isolated to the range itself.

In looking at the parts list, I'm thinking it is the gas pressure regulator that is likely the culprit.

I'd like to get your thought on what the problem is and how we might go ahead and fix it. We'd prefer to do it ourselves, but will get a repairman in if the problem can't be diagnosed or is too unsafe for laypeople (albeit very handy and mechanically inclined) to take on.

Gas and electrical problems are two issue most of us do not want to tackle. It does sound like you are careful and thoughtful in your approach though so the expert may be able to provide instructions to help. If you do decide to have an experienced technician, an option is to visit Sears Home Services to schedule. I attached the link below. I also added the schematics at Sears Parts Direct for your range that has a parts list also if needed. If you have time and wish to check the first link, it has lots of information in untechnical language that may help. Hope some of this helps!

So an update: My partner called an appliance repairman this morning and the guy asked if we'd been painting. Well, yes, we've been putting an oil-based stain on some bookshelves this weekend. He said to wait a few days for the stain to cure and the fumes to dissipate and we should be (hopefully) back in business. I hope this is the solution. We still have the high flames on the stove but perhaps they are licking up because of the petro-chemical presence. The smell is definately familiar but it doesn't smell like fresh natural gas (sulfur), it smells burnt so perhaps it is the odor of combusted petroleum which would be familiar. The other gas appliances (furnace, water heater, fireplace, dryer) don't seem to be having a problem (furnace is literally 5 feet from where I was applying the stain) but they vent to the outside so perhaps I'm just missing it.

Thank you for your question.

I can understand you concern with the gas smell of unburned gas fumes when the oven is operating.

You have done a good job with the diagnosis of the problem and I think the technician may have gotten it correct. Any oil based paint in a confined area will cause a strong odor.

Remember the gas range is the only invented gas appliance in the house.

If the regulator was having a problem it would affect the top burners as well.

The yellow in the flame is normal as long as it is just the tip. The lifting and blowing of the flame could be because you have the flame spreader off the burner and with the door open the air flow is stronger but usually the flame should not be lifting or blow torching off the burner.

Opening the primary air shutter on the burner can cause this. It will give the burner too much air and lift the flame off the burner ports.

Gas appliances have an inherent danger to them and I would consult with a gas appliance technician if the problem continues.

Thank you for using Manage My Life.
