I have been having troubles with the furnace in my 2021 Arcadia 3660RL. It occasionally works, but most often it does not. I have full plans tanks and have checked the fuse. I can hear a tick when heat is selected at the thermostat, but the fan does not kick in. I have actually banged in the exhaust port panel and it kicks in, however that does not appear to work any longer.
I don’t know where the access is to verify the voltage to/from control board. Any advice would be greatly appreciated.
