The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage 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 appear completely unresponsive: the outdoor unit simply won't energize even with a confirmed call for cooling.
