OEM Carrier 2-Pole 30 Amp 120V Contactor HN52KC052 for Model 09DE064C510

This genuine OEM Carrier contactor (part #HN52KC052) is the factory-specified replacement for the Carrier 09DE064C510. The contactor acts as the high-voltage switching relay that connects and disconnects power to the compressor and condenser fan motor each time your system cycles. When it fails, you may notice the unit won't turn on at all, chatters or hums continuously, or — in the case of welded contacts — runs non-stop even when the thermostat calls for no cooling. Replacing this contactor with the correct OEM part restores reliable, safe operation.

• Specs: 2-Pole | 30 Amp | 120V Coil | 50/60 Hz | Factory part # HN52KC052 | Cross-reference: 3100-20T628
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact coil voltage and contact-rating tolerances. Off-brand contactors often use lower-grade silver-alloy contacts that arc and pit faster, leading to premature failure and potential compressor damage.
• Install Difficulty: 2/5 — Shut off all power at the disconnect and breaker panel before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify coil voltage. Photograph all wire positions before disconnecting. Swap one wire at a time for accuracy.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model 09DE064C510. Verify your existing contactor's pole count, amp rating, and coil voltage against your unit's data plate before ordering. Not sure if this is your part? Our HVAC specialists confirm fitment before you buy — no guesswork, no return hassle.
