Make sure there is power at the compressor, but first at the contactor (being supplied to contactor ). Power being supplied to contacter (line voltage) ? Yes, then close contactor manually and if it works then check for 24 volts at the contactor coil. Find 24 volts, then you need a contactor. No supply (line voltage), then check breaker Breaker on, then check run capacitor and if good check high and low pressure protection.High pressure = trips on high head pressure (manual reset) then clean condenser coil. Low pressure trips on low charge (auto reset on restored charge)
