Furnace has gone rogue! Help! 2018 Forest River Spartan 1245 toy hauler
I have an odd situation. Iím guessing I need a thermostat but cannot confirm. My thermostat is turned completely off, and before it was it was set to AC on all settings, yet my furnace tried to come on. Nothing would turn it off so I pulled the fuse (since I donít need the furnace for a few months.) However, whats even more weird is the odd noise that came on once the fan would stop on the furnace. It sounds as though something is attempting to purge, or like a strange pump type noise. After pulling the fuse the furnace obviously didnít attempt to start again but every 15 minutes or so the odd purge/pump noise is back again. Apparently not furnace related but everything else is functioning correctly. It also does not stop when I kill the main breaker so must be linked to the battery? I am on shore power with a surge protector. Hooked to city water and itís raining if thatís matters at all. I believe I have a suburban furnace but without tearing into it I cannot confirm tonight at 1am and instead of a furnace manual I ended up with 3 hot water heater manuals in all of my paperwork for the camper. I am extremely lost so any help is very much appreciated!
