This is the genuine OEM replacement contactor for the Carrier 09DE109C100, factory part number HN52KC052. The contactor is the high-voltage switching relay that controls power delivery to the compressor and condenser fan motor. When energized by the 120V control coil, its contacts close and allow line voltage to flow to the load side of the system. A failing contactor is one of the most common causes of HVAC no-start conditions — symptoms include the unit humming but not starting, chattering or buzzing at the contactor, pitted or burned contact points, or the system failing to shut off when commanded by the thermostat.
Compatibility: Designed as a direct OEM replacement for Carrier model 09DE109C100. Verify coil voltage (120V) and amperage rating on your unit's data plate before ordering. Cross-references include Bryant and Payne units sharing the HN52KC052 specification. Need help confirming fitment?
