OEM Carrier 2-Pole Contactor 24V Coil for Model PH13NR03600GAFAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Carrier PH13NR03600GAFAA heat pump/split-system condenser. The contactor is the high-voltage relay that bridges 240V line power to the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — the outdoor unit simply won't start, even though the thermostat and control board are functioning normally. You may hear the indoor air handler running while the outdoor unit stays silent: a classic contactor failure symptom.

• Specs: 2-pole configuration | 24V AC coil voltage (thermostat-signal operated) | Rated for high-amperage compressor and fan motor loads | Direct OEM replacement for Carrier part number HN51KC024
• OEM vs Generic: This OEM contactor is wound, rated, and tested to Carrier factory specifications. Generic aftermarket contactors often use lower-grade contact alloys that pit and weld faster under the high inrush current of a scroll compressor, leading to repeat failures within a single season.
• Install difficulty: 2/5 — Disconnect and lock out power at the disconnect box before opening the unit. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Always photograph existing wiring before disconnecting terminals. Coil wires are low-voltage (24V); line-side terminals carry 240V — treat them with full caution even after disconnect.
• Warranty: Backed by Carrier's 1-year OEM parts warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
