Hello and welcome to just answer my name is ***** ***** I will be the one to assist you.

22 ABNORMAL FLAME-PROVING SIGNAL Flame is proved while gas valve is de-energized. Inducer will run until fault is

cleared. Check for: - Stuck open or leaky gas valve.

Customer: replied 10 months ago.
I can read the error code message and suggestion on the furnace cover too. I tapped both valves with no change,. Can I take the solenoid off that unit or that that unit apart to see what is sticking?
Customer: replied 10 months ago.
I tapped harder and it seemed to loosen up. Turned on the furnace with thermostat +1 degree higher than current temp and furnace kicked on. Turned thermostat setting to -2 lower than current temp and furnace turned off, like it is supposed to and the blowers stopped blowing after cool down. So looks like it is that sticky gas valve. What is the part number so I can order a replacement? Thanks, Garry

Due to the hour I can not narrow that serial down, as there are 3 different ones. Call this number in the morning and they can get you it for sure.

Hi there,

I was just touching base with you because I have not heard back from you and the question is still open and unrated, I am not credited anything until a good star rating is supplied thank you.
