Atwood Heater Problems

[rantin]

Like many others I too am having Atwood furnace problems. No fan, no ignition, nothing. Gas on and plenty of it. Thermostat set to 89, fan to auto, and set to furnace, both thermostats set the same. Stove works, water heater works on gas but no heat.from furnace Saw a video of a guy with a Jayco and he found a hidden switch on the duct work behind the wet bay. Wondering if we Montana owners have a hidden switch too. Also, I took the cover off the furnace and tried the reset switch with no luck. I even disconnected all power 120 & 12 volt. Still nothing. Gotta be something turned off. This is the first time I've tried to use the furnace (new unit). Guess I'll empty storage bay to access behind wet bay tomorrow and see if I can find a hidden switch. Scratching my head,...... Unit is a 2018 3561RL

Mine is a much older unit but there is a rocker switch, on mine, on the top of the furnace. One of the 12v wires goes through the switch. I had to follow the wires to find the switch because there isn't much head room to see it. My issue was a wire had come off the terminal on the switch.

If you have the Atwood’s furnace in your trailer, the switch you’re hunting is likely near the furnace, itself. Remove the furnace’s outer cover (10x Phillips-headed screws)
A rocker/reset switch is directly under the cover.
The location of the switch is/as I mentioned on our 2018 305RL w/Atwood HydroFlame series (vertical) furnace.

Our furnace recently gave us trouble, also. Turned out to be a faulty circuit board in our case. I replaced the board with one from Dinosaur Electronics—made in USA & has 3 yr warranty.

Thanks to everyone for you help. My RV tech and I are starting to narrow it down but it's raining here so I can troubleshoot till it stops. I'll advise when we find the culprit.
