Duo-Therm comfort control module

[Gavin]

While visiting Grand Tetons I had need for furnace on a morning and discovered "Furnace" option had disappeared from the AC controller since I last used it. I have checked for loose wiring, etc.
Could this be bad module? All other options (AC, Heat Pump,etc.) are fine.

That's an odd one.

I would try turning the whole system off for a few moments and then back on. I would do this at the little switch on the bottom of the Duo-Therm

I would also check my 12 automotive fuses to make sure that the one that controls the furnace circuit has not blown or come out of place.

I would also open the furnace access door on the outside of the trailer and check to see if any wiring has come loose.

Thanks Moosetags; it worked. I turned the unit off and back on as you suggested and it did the trick.

Glad to hear that you got it working.
