Hey everyone.

I have an Atwood AFMD 35131 Furnace.

When I turn the thermostat on I either get cool air blowing (instead of hot) or it just shuts off.

Circuit board has no blinking lights indicating “Internal Control Failure”. What does this mean to me? I tried cleaning up the circuit board the best I could but it already looked pretty clean. I also checked the sail switch which was clean.

Do I just need a new circuit board? Easy enough for a novice to complete?

Thanks!
