This answer was rated:

I have a new gas range, and I hear a persistent hum when I use a burner. It usually goes away when I turn on a second burner, but not always. How do I fix this?
Hello i have a few questions first. How old is the unit? Where is the hum coming from? and what is the model number of the unit? Thank you

The unit is brand new. Just installed within the last two weeks. It is a Frigidaire FGF368GMC. The hum comes from the burners/cooktop, not from the back of the range. It gets louder or softer if I change the heat intensity, but it's not louder when the burner it hotter, etc. No rhyme or reason to it, really. If I turn on another burner, the hum goes away usually, but occasionally comes back.
It sounds as though you might have some bad switches. However because the unit is brand new i do not suggest trying to fix the unit yourself(you might void the warranties on the unit) You can call the phone number in your owner's manual for service. All appliances come with a 1 year standard unit. Thank you

Just so I understand better, what are the switches? The unit lights the burners just fine. It's when they are burning that I hear the hum.
ah ok. there are air guides underneath the top that sound like they need to be adjusted. The regulate the air/gas flow. If they are not adjusted properly you can hear some strange sounds and have some discoloration in the flames, it is also possible that the caps and burner assembly may be partially deformed as well. casuing the inconsitent air flow.

Is this something I can adjust myself?
Honestly you are looking for a professional on this one. If They are not adjusted correctly they can be producing carbon monoxide. You should have a trained proffesional look at this. Thank you and if i've answered your question please click accept.
