Gas valve circuit error-furnace

Jgolden · 01-01-2012, 01:04 PM

I have an american standard freedom 80 comfort-r furnace.the burners will only light up for a few seconds and then will shut off. It continues to try and light up but with no success. According to the 7 flashing lights, it says that it is a gas valve circuit error.what can I do to fix this?

try cleaning the flame sensor. one wire to it, thin metal rod possibly shaped like an L that sits directly in the flame so look for it in the burner area. use a scouring pad like the green rough dish washing ones.

Locate, remove and clean the flame sensor........steel wool, Emory cloth or a fine grit sand paper

a 7 flash gas valve circuit error is that 24V is present on the gas valve circuit when it should not be. However, what you describe is not a symptom of a 7 flash error. Are you sure you counted the LED flashes correctly. What you have described sounds exactly like a dirty flame sensor as the others have instructed you to clean.

I meant "I win" because I snuck in my answer first.

Congratulations, did you do a victory burn out? I was not aware that this was a competition.

Doc Holliday · 01-01-2012, 02:07 PM

Never mind.

Jgolden · 01-01-2012, 02:09 PM

Wow, that was just too simple.

Doc Holliday · 01-01-2012, 02:14 PM

So the flame sensor was the problem?

I guess so, it's working now. Thanks!
