The contactor is a high-voltage relay that receives a 24V signal from the thermostat or control board and closes to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will not respond to a cooling call, leaving the unit completely unresponsive despite the thermostat signaling demand.
