My furnace isn't working; Coleman, DGAA056BDTA
The furnace indicator flashes twice, which means it's saying the combustion air switch is stuck shut.
It doesn't ignite, there is no flame visible in the viewing window.
I've replaced the pressure switch/combustion air switch, which did not solve the problem and I still get 2 flashes, indicating it is stuck closed.
On the circuit board I notice one area with what appears to be overheating; it's apparently a slight burning of the board in a small area.
The induction motor is mounted to the right of the pressure switch which I replaced; it's mounted on the vent flue which goes to the roof and it'll be very difficult for me to reach 2 of the 4 screws. Do I need to get in there to do anything?
Hoping for any knowledgeable, helpful suggestions; I'm trying to do it myself so as to save money.
