The contactor acts as a high-voltage relay, using a 24V signal from the thermostat control board to close the high-voltage circuit that powers the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will not respond to a cooling call, leaving you with a unit that hums, chatters, or simply does not start.
