Hi all,
I'm a bit mystified by this issue. My Ollie has the Suburban/Attwood furnace and when I bought the trailer, the previous owner, I thought turned on the heater. They ran through most of the trialer operations and were very helpful. Since I've owned it, I had to get a Truma Aqua Go water heater installed, which I did. That's about the only thing I've done to it. I thought the furnace heater worked, but now that I'm trying to get it to turn on, it's only kicking on the Dometic AC fan. Are they two completely different systems? I don't see a separate thermostat for the Suburban furnace, so my reading and searching says it works from the Dometic thermostat, but that doesn't seem to work. I tried holding the Mode button and the Up arrow to reset the thermosat. When I turned it to furnace after that, the Dometic ac fan didn't turn on, but nothing happened. Also, I did check and replace the furnace 7.5amp fuse, just to cover that. Also, I checked that the propane is turned on.
Anyone have any insight. What am I missing?
