The contactor is a high-voltage relay that receives a 24V signal from the control board and closes the circuit to send line-voltage power to the compressor and condenser fan motor. When the contactor fails — due to pitted or burnt contacts, a stuck plunger, or a failed coil — the system will not respond to a call for cooling, may run continuously without shutting off, or will trip the breaker repeatedly.
