What is the differential between room ambient temperature and thermostat set temperature. If more that 3 degrees F it will revert to propane furnace. Try setting the thermostat to 2 degrees above ambient temperature.

No problem in cooling mode only with heat pump

That's a good sign, your compressors are okay.  There could be a problem with the reversing valve, control board or thermostat. To rule out the thermostat, use my truth table to see if 12V going to W1 (white/black wire) when electric heat is called.

You are probably aware the thermostat is somewhat smart (barely) and if the set temperature and ambient temperature is equal to or greater than five degrees, gas heat will be called. Then the thermostat will periodically attempt to call for electric heat and then finally give up on electric.

Oh boy, I hate intermittent problems. I had an sporadic problem with my heat pump when it wouldn't cool after a long day on the road, this started when the coach was new. Everything that could have been replaced (thermostat, control board) was replaced with no resolution. Finally RVP replaced the entire unit which cured the problem. This only took two years  ::) .

 You're welcome John, I bookmarked every thread I've came across and every link in those threads. Hopefully when my basement unit stops working(we know it's gonna happen), something within those links will guide me through the repair process or point me to where to buy a replacement.
The only thing I don't have linked is the height of the platform required to support the unit when it is removed from the MH, and that must be measured with air dumped; that might be different for each MH.
