Hi all. We find ourselves here in Cedar Rapids Iowa during one of the worst winter snow storms ever. Our furnace worked all the way here (from Arizona), and we shut it off for a few hours since we weren't going to be in the RV. When we tried to turn it back on, it wouldn't run at all. We've checked fuses, tried to track wiring, etc. There seems to be no power going to the dinosaur board (the ight isn't on), and the blower fan doesn't come on. Any help would be hugely appreciated.

There should be a breaker that supplies the power to the furnace and a fuse on the motherboard
The gas furnace is a 12 volt system so there is not a breaker for it, rather a fuse.
Do you have a voltmeter? If not, I suggest you get one to keep on board as you will need it. I would check to see if you do have 12 volts for sure at the fuse panel. Then you don’t mention what model you have, but most have one or two wooden vent grills either below the cooktop or the fridge, you should be able to access the backside of the furnace or outside under the access cover, verify that you have 12 volts at the furnace. There are also fuses on the back of the thermostat. Also, yiu can only control the gas furnace with the front thermostat, not the rear one.
