OEM Carrier 2-Pole 30A Contactor 120V Coil (HN52KC052) for Model 09DE064100

This OEM contactor is the factory-specified replacement for the Carrier 09DE064100 HVAC system. The contactor is a high-voltage relay that closes the circuit to the compressor and condenser fan motor every time your thermostat calls for cooling. When the contactor fails, the most common symptom is an air conditioning system that simply will not turn on — the indoor air handler runs, but the outdoor unit stays completely silent. A pitted, burned, or stuck contactor can also cause erratic cycling, voltage drop at the compressor, or welded contacts that keep the unit running non-stop.

• Specs: 2-pole design | 30-amp rating | 120V coil voltage | 50/60Hz frequency | OEM part number HN52KC052
• OEM vs Generic: This is the genuine Carrier factory part, matched to exact coil pull-in voltage, contact gap, and ampacity ratings. Generic contactors frequently use thinner silver-alloy contact surfaces that pit faster under the high inrush currents typical of compressor starts — accelerating failure and risking compressor damage.
• Install difficulty: 3/5 — Always shut off power at the disconnect and the breaker before servicing. Confirm zero voltage with a meter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a camera to photograph wiring before removal. Label all wires before disconnecting.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model 09DE064100. Verify coil voltage (120V) and pole count (2-pole) on your unit's data plate or wiring diagram before ordering. Not for use with 24V coil applications. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy — contact us today and get your system back up and running fast.
