OEM Carrier 2-Pole Contactor 30A 120V Coil for Model 09DE109500 (HN52KC052)

This OEM Carrier contactor (part number HN52KC052) is the factory-specified replacement for the Carrier 09DE109500 HVAC unit. The contactor functions as the primary high-voltage relay in your system — when the thermostat calls for cooling, the 24V control board energizes the contactor's 120V coil, closing the high-side contacts and delivering line voltage to the compressor and condenser fan motor. When a contactor fails, symptoms include an AC system that won't energize at all, a compressor that hums and trips on thermal overload, or contacts that weld shut causing the system to run continuously even when cooling is not called for.

• Specs: 2-pole | 30 Amp | 120V coil | 50/60Hz rated | Factory OEM part number HN52KC052 | Replaces worn or pitted contact surfaces
• OEM vs Generic: This genuine Carrier OEM contactor meets exact factory contact gap, spring tension, and coil impedance specifications. Aftermarket contactors can suffer from coil resistance drift and premature contact pitting under high-load cycling conditions.
• Install difficulty: 3/5 — Always shut off power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify coil continuity and contact resistance). Photograph all wire terminations before removal. Pull-and-replace procedure is straightforward, but line voltage terminals require careful torquing.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier 09DE109500 HVAC unit. Verify your unit's control voltage (120V coil) and amperage rating on the data plate before ordering. If you're unsure of fitment, our technical team is available to confirm compatibility before you purchase. Order today and benefit from same-day shipping on all in-stock parts.
