OEM Carrier 2-Pole 35A Contactor HN52KC053 for Model YAC42110YAC202AK

This is the factory OEM replacement contactor for the Carrier YAC42110YAC202AK condensing unit. The contactor is the primary high-voltage switching relay in your outdoor unit — it receives a 24V signal from the thermostat and closes its contacts to energize the compressor and condenser fan motor. When a contactor fails, the most common symptoms include the air conditioner not turning on at all, audible chattering or buzzing from the outdoor cabinet, or — in the case of welded contacts — the compressor running continuously even with the thermostat off.
