OEM Carrier 2-Pole Contactor 35A 208/240V for Model 09DE164C230

This OEM contactor (part number HN52KC053) is the factory-specified high-voltage relay for the Carrier 09DE164C230 system. The contactor is the critical switching component that receives a low-voltage 24V signal from the thermostat and closes the circuit to send high-voltage power to the compressor and condenser fan motor. When it fails — due to pitted contacts, a stuck plunger, or a burned coil — the system will typically hum, fail to start entirely, or trip the breaker repeatedly. Replacing a worn contactor promptly protects your compressor from costly short-cycling damage.

• Specs: 2-Pole | 35 Amps | 208/240V load voltage | 24V AC coil | OEM Part # HN52KC053
• OEM vs Generic: This is a genuine Carrier OEM contactor manufactured to exact factory contact-gap, spring tension, and coil-pull-in tolerances. Generic aftermarket contactors frequently use lower-grade silver-alloy contacts that pit faster under compressor inrush current, leading to premature failure.
• Install Difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph existing wiring before removing any leads.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.
