OEM Carrier Contactor HN52KC052 for Model 09DE064C900

This OEM contactor (part number HN52KC052) is the factory-specified high-voltage switching relay for the Carrier 09DE064C900 condensing unit. The contactor is the critical electrical component that receives a 24V signal from your thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your outdoor unit simply won't energize, even though the thermostat is calling for cooling. You may hear a hum from the control board with no response from the condenser.
