The contactor is a high-voltage relay that receives a 24V signal from the thermostat or control board and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — through burned or pitted contacts, a stuck plunger, or a failed coil — the system will either refuse to start entirely, run continuously without shutting off, or trip the breaker repeatedly.
