Arrived onsite for no AC. Turned thermostat is on cooling. Confirmed inside air handler is operational. Went to roof to look at outside condenser unit. Found the unit turned off at the service switch. Turn switch on but no power to the system. Went to breaker room and did not find any circuit breakers tripped. Performed continuity test on compressor. Did not find the compressor grounded. Did measure continuity between compressor terminals had an initial high ohm but all three settled at 9 ohms. Possible motor winding issue but need power to the unit to confirm. Recommend having an electrician fox power to the outdoor unit.
