OEM Carrier 2-Pole Contactor for Model HB1CJX060000AAAA — Part HN52KD020

This is the factory OEM replacement contactor (part number HN52KD020) for the Carrier HB1CJX060000AAAA condensing unit. The contactor is the high-voltage switching relay that receives a 24V signal from the thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When it fails, the most common symptoms include the outdoor unit refusing to start, the compressor humming but not running, or the unit staying on continuously due to welded contacts. A failed contactor is one of the most frequent causes of a no-cooling call in the field.
