OEM Carrier 2-Pole 30 Amp 120V Contactor HN52KC052 for Model 09DE054C900

This is the factory-specified OEM replacement contactor for the Carrier 09DE054C900. The contactor is the high-voltage relay responsible for switching line-voltage power to the compressor and condenser fan motor each time the thermostat calls for cooling. When the contactor fails — due to pitted or burned contacts, a stuck armature, or a failed 120V coil — the system will either refuse to start entirely, run continuously without shutting off, or produce a loud chattering or buzzing at the outdoor unit. Replacing it with the correct OEM part restores reliable, factory-spec switching performance.

• Specs: 2-Pole | 30 Amp | 120V AC Coil | 50/60 Hz | Single Phase | Part No. HN52KC052 | Factory Authorized Parts designation
• OEM vs Generic: OEM contactors are manufactured to Carrier's exact coil voltage tolerance and contact gap specifications. Generic contactors often use lower-grade contact materials that pit and weld faster under load, leading to premature failure and potential compressor damage.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, voltage tester. Photograph all wiring before disconnecting. Snap in the new contactor, transfer wires one at a time, and restore power to verify operation.
• Warranty: 1-year OEM factory warranty against defects. In-stock orders ship same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier model 09DE054C900. Always verify coil voltage (120V) and amperage rating (30A) against your unit's data plate before ordering. Our team is available to confirm fitment — just reach out before you buy.
