For the past few weeks I've noticed that my heating system doesn't turn on. I've traced it back to the ignition system not lighting.
Sometimes it just sits and clicks, then shuts off. I have to reset the system to start again, eventually it will light.
Also, it seems that it turns off before it reaches it's target temp alot.
I read a fix for the ignition problem could be:
The ignitor has a thick Gray(or Blue) tube-like wire going straight to the control circuit board to a one inch round device. Pull it off, trim 1/4" to 1/2" off and push/turn it back on.
As for the furnace stopping before it's target temp, could that be the flame sensor?
Thanks for your responces...
