The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the call for cooling comes in, the contactor closes to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't turn on, hums without starting, or experiences intermittent operation. Pitted or welded contacts, a burned coil, or a stuck plunger are classic failure signs.
