The contactor acts as the primary switching device that connects line-voltage power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When the contactor fails — due to pitted contacts, a burned coil, or contacts welded shut — the most common symptoms are an AC system that won't turn on at all, a unit that runs continuously without cycling off, or visible arcing and burning at the terminal block.
