Furnace

I have a 2020 hummingbird MBS and I can’t get the heater working. Does the on off switch really only move about an 1/8 of an inch? Really simple controls but they don’t work.

Lots of posts on furnace issues to research via the search bar above. The factory thermostat has a little slide switch with off/on that moves only a fraction of an inch. If everything is working right and the temp is set several degrees above what it looks like on the very inaccurate scale of the stat you will hear tiny click as the thermostat sends 12 volts to the furnace, furnace fan comes on, burner lights after a few seconds and heat comes out.

If nothing happens pull off the stat and see if wires are connected. Check if there is 12 volts to the wires. Then research all the reasons a furnace goes bad from there.
Then look up and buy a digital thermostat.

Yes the on/off switch doesn’t move much.

Did the furnace work during the PDI with the dealer when you bought the camper?
