What exactly what seems to be going on with the unit
THis sounds actually sounds more like a thermostat issue than something with the furnace.Have you replaced batteries?
Yes that is why I thinking thermostat.If it were in unit you would have to turn power off and back on at unit.
I suspect with the thermostat itself.May have taken a power spike.Erratic operation is usually a sign something has taken a spike. May be a rest on it.
I would start by Getting model on thermostat and Googling to locate an online manual. Follow any instructions in manual for a reset from power spike if it has one.If not or if that does not solve problem, replace thermostat.
