Furnace Not Working

[jsjustice7]

We have a 2018 362RD that we are living full time in. In preparation for cold weather I tried running the furnace and cannot get it to run. The outer blower won’t turn on and the igniter won’t click. The furnace fan runs for about 30 seconds and shuts off. I’ve check the power from the battery to the fuse panel and the fuse panel to the circuit board. There is power to the board and reset switch but nothing else seems to have power when calling for heat from the thermostat. The red led on the circuit board won’t come on at all. It looks like I have 4 wires coming to the unit. Red, Black, and 2 blues. The blue wires go directly to the side of the blower motor and there isn’t power on them when calling for power from the thermostat. Is this a circuit board issue or thermostat. The thermostat controls the rear AC, rear Heat pump, and furnace. The ac and heat pump work fine. I have full propane tanks and everything else that can run off propane works. I’m electrically challenged but can work through things. The unit is an Atwood AFMD35. Thanks
