Hi All

Have a 2016 377 5th wheel Been using elec heat and works pretty good but when colder (40) not so we'll. Tried propane but nothing no fan goes on. Just filled propane and have power. Looking for unit to see if there is a switch or propane turn on. Where is the furnace? Roof? Sure I'm just missing something stupid. Atwood heater

The heat pump (electric heat) only works above 40F. When the temperature drops below that, the furnace automatically takes over. If you have full propane tanks and it’s not coming on, I would check the fuse box and then the “secret reset switch”. The furnace is located next to the water heater and is accessed by removing the false wall in the basement storage behind the water works panel. See video

I have similar problem with my 2018 Eagle but fan comes on momentarily (30 seconds) each time thermostat is activated..., and then shuts off with no heat. I can hear the fan and feel air come out of floor vents each time. Tried it multiple times.... no luck. Propane works for oven, and battery power good at over 13 volts. Also hooked up to shore power now and have same problem. - - - Is this "seacret reset switch" behind false wall common to all Atwood furnace systems?

I had a similar issue on my 2018. Sounds like you might have a bad sail switch. The switch has a small paddle/sail that moves by the pressure from fan wheel running. When the fan starts up the pressure moves the "sail" which in turn allows the gas to flow. If the switch is defective, it doesn't activate which prevents flow of gas.

There are other components as well but this is a pretty cheap first check if you know you have gas flow. The switch costs about $5 to $8. Any RV parts provider can get you the right one by providing your furnace model number.

Yes I believe they all have it. OP, try the reset switch that Tom referred too first. If that doesn't work check/ replace the sail switch as mentioned above.

Late with my reply but Thank you all. New sail switch did the trick.
