Second furnace

[Saab guy]

Hello again, well I've moved on to check the furnaces out. The furnace for the front of the coach now works had broken wire in the kitchen slide and the front ac unit. That sent a signal to furnace to come on, but I'm not sure where the furnace under the fridge gets its signal t/stat only has one zone with furnace on it. Zone two has no furnace mode to turn on does zone one turn on both burners 2002 HR endeavor DP any help would be great

Thanks Bill

Which thermostat do you have.

If you have the 4 button Duotherm, do a reset to see if that helps.

1. Turn the thermostat off with the slide switch on the bottom.
2. Press and hold the top (Mode) and bottom (Zone) buttons.
3. Turn the thermostat on with the slide switch.
4. Release the buttons.
5. The thermostat should show FF to indicate it's been reset.
