Job Checkin

Found the outdoor not communicating with the indoor system. The outdoor unit was locked out. I reset the system on high voltage and low voltage. The outdoor unit would come on for about 5 seconds when I pressed the test pin. I verified that I have DC voltage to the outdoor unit for the system to communicate, that I have 24v voltages on R, and that the system is good. The coil sensor is reading 24kilo ohms and that indicates it is 43 outside with the reference of a thermistor temp/ohm scale. I confirmed the system has refrigerant. I reached out to tech support and sat on hold. I didn’t get anyone on the phone.
