None of the ducts kinked, plenty of propane. I changed to a Coleman digital thermostat about 6 months ago. When it cycles off, 2 zeros are visible in the window (for a brief period) instead of temperature settings.
During the cycling the fridge display lit up, one of the figures changed to yellow instead of green.
We're about 200 miles from home, so guessing to head home & CW for repair.
Any ideas welcomed, that might save the trip.
Thanx

Changed back to original thermostat, worked ok on first use, next time it cycled on same troubles.
Wondering if it's like a thermal limiter causing this. I carry a portable electric that helped a little, buying another today.
It's a Dometic DFMD35151

The furnace supplies 12 VDC power to the Thermostat. Sometimes the fridge control power runs off the same circuit as the furnace.
If you have a bad control board in the furnace it may be temporarily drawing enough current to cause a sufficient to drop the voltage to the thermostat to initialize the display (00) and freak out the fridge controls. Bad control boards are common in these furnaces, if you replace it I highly recommend a Dinosaur control board which has a 3 year warranty and is a better product.
