The contactor is the 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 — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will not cool, the compressor will not energize, or the unit may run continuously without cycling off.
