OEM Carrier 2-Pole 30 Amp 120V Contactor HN52KC052 for Model 09DE164100

This genuine OEM contactor is the factory-specified replacement part HN52KC052 for the Carrier 09DE164100. The contactor acts as a high-voltage relay, regulating electrical flow to critical components — including the compressor and condenser fan motor — enabling them to start and stop on command from the control circuit. When a contactor fails, the most common symptoms include the system refusing to turn on, chattering or loud humming from the condenser cabinet, welded contacts that keep the unit running continuously, or the compressor and fan motor failing to energize at all.

• Specs: 2-Pole | 30 Amp | 120V Coil | 50/60 Hz | Factory OEM part number HN52KC052 (cross-ref: 3100-20T628)
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact manufacturer tolerances for coil pull-in voltage, contact resistance, and arc interruption rating. Generic contactors often use lower-grade contact materials that pit and weld faster under load, shortening equipment life.
• Install Difficulty: 3/5 — Requires disconnecting main power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and voltage tester. Always photograph existing wiring before removing the old contactor. Verify coil voltage on your unit's data plate matches 120V before ordering.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse — order before cutoff and get back up and running fast.
