OEM Carrier Contactor 2-Pole 24V Coil for Model 09DE084C600

This is the factory OEM replacement contactor (part number HN52KC052) for the Carrier 09DE084C600 unit. The contactor is a high-voltage relay that serves as the main electrical switch between the 24V thermostat control signal and the high-voltage power supplied to the compressor and condenser fan motor. When the thermostat calls for cooling, the control board energizes the contactor's 24V coil, closing the contacts and allowing line voltage to flow to the compressor. A failed contactor is one of the most common causes of an air conditioner that won't turn on, hums but doesn't start, or intermittently loses cooling — often visible as pitted or burned contact points upon inspection.

• Specs: 2-Pole design | 24V AC coil voltage | Factory-rated amperage matched to Carrier 09DE084C600 | OEM part number HN52KC052
• OEM vs Generic: This OEM contactor is manufactured to exact Carrier factory specifications, including precise contact gap, coil pull-in voltage, and rated load amperage. Generic contactors can have loose tolerances, leading to premature contact pitting, coil burnout, or nuisance tripping under load.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify voltage is absent with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for the Carrier model 09DE084C600. Always cross-reference your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate to confirm fitment. Our technical team is available to verify compatibility before you order — no guesswork required.
