The contactor acts as the primary electrical switch that connects line voltage to the compressor and condenser fan motor when the thermostat sends a 24V signal. When the contactor fails — whether due to worn contacts, a burned coil, or pitting from electrical arcing — the system will fail to respond to a cooling call entirely, or may run continuously without shutting off.
