OEM Carrier 2-Pole Contactor 40A 24V Coil for Model TCHC0250HEFMRAF132

This is the genuine OEM replacement contactor for the Carrier TCHC0250HEFMRAF132 system, factory part number HN52TC040. The contactor is the high-voltage relay that bridges the 24V control circuit to the high-voltage compressor and condenser fan circuits. When the thermostat calls for cooling, the 24V coil energizes and pulls in the contacts, sending line voltage to the compressor. When this part fails, the most common symptom is the outdoor unit simply not turning on — even though the thermostat is calling and the air handler is running — or intermittent cycling caused by worn or pitted contact points.
