Outdoor fan is running with out the compressor. Checked Circuit board on heat pump to see if there was any LEDs that were flashing any codes. I couldn’t find any. I reset the power for three minutes turned it back on put my gauges on the unit left my Aunt probe on the incoming power temperature sensors on the indoor unit and started the system. I could hear the EXV opening heard the compressor start. With both heads calling for cooling and temperature set on the thermostat as low as possible forced outdoor unit into high. Amp draw is seven for the compressor and the fan. Delta T is 28 and refrigerant pressure is 120. I suspect that there might’ve been a power surge of some kind that caused the board not to start the compressor. But if this happens again, we’ll call tech-support and take a little deeper.
