Hey all, another furnace question / issue I'd love some help troubleshooting.
I've got a 2019 Fleet with the Atwood furnace. It's always been a little quirky, but I thought once I figured out the trick to remove the piece ductwork to the grille all my problems were solved, but here we are again and it's acting up.
I was out this weekend in cold weather, and turned the heat on. The fan kicked on, ignitor clicked, and after a minute or so I started to feel warm air blowing, yay! But then it just stopped entirely. No fan, nothing. It took me a minute to figure out, but the fuse had blown. I had some extra 7.5 amp fuses, and popped one in, and turned the thermostat back on, and the fuse blew again immediately.
I found some service and did a little research, and found folks recommending a 10 or 15 amp fuse (along with plenty of counter advice on that). I figured I'd try a larger fuse just to see if I could get it working, and both 10 and 15 amp fuses blew immediately as well.
Back home now, I put some fresh 7.5amp fuses in, and now when I turn the thermostat on nothing happens at all – the fuses don't even blow!
I removed the outer furnace cover to hit the reset switch and still nothing.
The blower fan looks clean and is clear of debris.
I removed the cover to the thermostat, and all looks good there. I tried bypassing the switch and just connecting the two wires in there, and nothing happened.
I recently installed a new battery and Renogy 500a battery monitor and shunt. I've double checked all of that wiring and nothing is shorted and everything is exactly the same as it was before the battery replacement.
All other electronics in the camper are working — lights, USB, fridge, etc.
Any ideas? Appreciate it!
