The contactor acts as a high-voltage relay, receiving a 24V signal from the thermostat control circuit and switching line voltage to energize the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a stuck or burned coil, or worn contact tips — the most common symptoms are an air conditioner that won't turn on at all, a compressor that hums but won't start, or a unit that runs continuously without cycling off.
