OEM Carrier 2-Pole Contactor 35A 208/240V — Model 09DE109230

The Carrier HN52KC053 is the factory-specified 2-pole contactor for the 09DE109230 unit. The contactor acts as a high-voltage relay, switching 208/240V power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When this component fails, the control board sends the 24V signal but nothing happens — the outdoor unit stays completely silent even though the indoor air handler is running. A failed or pitted contactor is one of the most common causes of a no-cool call in residential and light-commercial HVAC systems.
