Flaky Furnace Thermostat
I have a Suburban gas furnace in my 4-year old 5th-wheel. The thermostat name on the front panel is "RVComfort.HP". When heating on propane only (that is, not using the heat pump), four times in the p...

The new one you have might work if you want to isolate the furnace as the heat source. But the actual furnace wires that would go to its
Tstat need to be identified.
On my old time Atwood furnace it is two blue wires that go to the Tstat and are switched there. On my new digital Honeywell, one goes to the W and one goes to R and it doesn't matter which goes to which.
On yours, you need to find the two wires, whichever they are, that come from the furnace that the Tstat switches. Then put them on W and R and it ought to work.
They should start the furnace just by touching them together, so I suppose you could take them all off the OEM and start touching them until you find the two that make the furnace start. (Not sure that is such a good idea in case it hurts some thing else)
On mine you can see the two blue wires leaving the power end of the furnace and going through a wall as a pair, and they come out at the Tstat.
Perhaps your furnace has something visible like that for the wires that go off to the Tstat. Perhaps a wiring diagram exists for that furnace in your rig.
