OEM Carrier 2-Pole Contactor 30 Amp 120V Coil for Model 09DE084810

This OEM Carrier contactor (part #HN52KC052) is the factory-specified high-voltage relay for the Carrier 09DE084810 HVAC system. The contactor acts as the primary electrical switch that energizes the compressor and condenser fan motor every time your thermostat calls for cooling. When the contactor fails, the system either won't turn on at all, chatters or buzzes audibly at the unit, or the contacts weld shut — causing the compressor to run continuously and risk burnout. Replacing a worn or failed contactor is one of the most common and cost-effective HVAC repairs available.

• Specs: 2-Pole | 30 Amp | 120V Coil | 50/60 Hz rated | OEM part number HN52KC052 | Factory-matched electrical ratings for safe, reliable operation
• OEM vs Generic: This is a genuine Carrier OEM contactor — not an aftermarket substitute. OEM contactors meet exact factory contact material, spring tension, and coil voltage specifications, ensuring proper pull-in voltage and long contact life. Generic contactors often exhibit premature pitting and inconsistent coil pull-in, leading to repeat failures.
• Install difficulty: 2/5 — Always disconnect power at the breaker and discharge any capacitors before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Swap wires one at a time to avoid miswiring.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
