working on a 137k BTU comfortemp heat pump. No display despite proper power input. Capacitors and transformer have been tested by a qualified HVAC technician. No clue why the display does not come on.
A quick search on Google confirmed that at least a few others have experienced out of box problems with these units. Any ideas or any known solutions? I’m leaning toward it being a bad main control board but hoping to see how others resolved the issue
