The contactor is a high-voltage relay that energizes when the thermostat sends a 24V signal, closing the circuit to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will fail to start entirely, run continuously without shutting off, or trip the breaker.
