OEM Carrier 2-Pole Contactor 35A 208/240V for Model 09DE146900

This OEM Carrier contactor (part number HN52KC053) is the factory-specified high-voltage switching relay for the Carrier 09DE146900 unit. The contactor acts as the primary electrical gate between your thermostat's 24V control signal and the 208/240V power circuit that energizes the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the result is an air conditioner that won't turn on, fails to cool, or runs continuously without shutting off. Replacing a worn contactor is one of the most common and cost-effective HVAC service repairs available.
