The contactor acts as the primary switching device that allows 240V power to reach the compressor and condenser fan motor when the thermostat calls for cooling. A failed contactor is one of the most common reasons an air conditioning system appears completely dead — the thermostat calls, the air handler runs, but the outdoor unit never energizes. Pitting, burning, or welded contacts are telltale signs it's time for a replacement.
