The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or stuck contacts — the most common symptom is the system failing to turn on at all, or running continuously without responding to thermostat commands. This direct OEM replacement ensures factory-matched electrical performance and long service life.
