The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the stat calls for cooling, 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 conditioner won't turn on, hums without starting, or runs continuously without shutting off. Burnt or pitted contacts, a stuck plunger, or a failed coil are all telltale signs of contactor failure.
