I plugged the unit in; it ran then it just turned itself off. I checked the plug, the breaker box and its all working and have power. I have tried to unplug, wait 3 minutes and plug it back in but I get no power on the display. Is there something that might need to be reset on the unit, and if so were it located.
When I'd run my unit for a few hours, the panel stopped responding, it wouldn't change any settings, either with the remote or if I pushed the panel buttons. I couldn't even turn it on or off. When I went to check the thermostat plug I found a moth coccoon attached to the circuit board and a LOT of dirt. I cleaned it, and no more problems. Thank you, this was the only place I could find troubleshooting for this unit.
I was having the same problem....take off the display plate to see the mother board....take out the five screws....UNPLUG FIRST!!!!....tHE WIRE GOING FROM THE THERMOSTAT MAY BE UNPLUGGED...IT'S A LITTLE TWO PRONG PLUG PROBABLY ON THE LEFT HAND, MIDDLE
