OEM Carrier Contactor HN52TC040 for Model TCHC2550HECMRAP602

This OEM replacement contactor is the factory-specified part for the Carrier TCHC2550HECMRAP602 system. The contactor is the high-voltage switching relay that receives a low-voltage (24V) signal from your thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an air conditioner that won't turn on at all, a compressor that hums but doesn't start, or pitted/burned contacts that cause erratic or intermittent cooling operation.
