Last night, I noticed that a burner on my cooktop was giving off a yellowish flame, indicating insufficient air in the mixture. I turned on the other three burners and got the same yellow-ish flame.

Because it affects all four burners, I’m guessing it is caused by an obstruction to the air intake that feeds all of the burners, and the fix may be as simple as removing a clump of dog hair somewhere. I can’t figure out where that would be, though. My trusty Reader’s Digest fix-it-yourself manual says I should be looking for an air shutter somewhere. I have successfully lifted up the cooktop to expose the guts, but I can’t find anything that looks like the picture in the book.

Suggestions?

Most likely it has to do with gas pressure. Bad or weak regulator, low gas pressure. Are you on propane?

The burners each have a air shutter. I believe its the "clamp" in this picture.

Thanks for the reply.

Natural gas. If each burner has its own air shutter, it seems unlikely that all four shutters went funny. Is there a way to test the regulator, other than by replacing the old one and seeing what happens?

You could call your gas supplier and have them check your house regulator.

Most appliance places can check the regulator inside the range.

Do you have anything else that runs on natural gas? You might check their burner flames.

If you have a humidifier in the house shut it off for a day and see if it fixes your problem. Just had a friend call me yesterday about this and fixed his problem.

Eureka! (Probably.) Just got a new ultrasonic humidifier the same day I noticed that the flame color changed. I've switched off the humidifier and will check the stove later this afternoon. You probably just saved me a $ervice call!
