OEM Carrier 2-Pole Contactor 24V Coil for Model HP13PR04800GAKAA

This is the factory-specified OEM replacement contactor (part number HN51KC024) for the Carrier HP13PR04800GAKAA heat pump. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the outdoor unit will not energize at all, or may run continuously without cycling off, leaving you with no heating or cooling.

• Specs: 2-pole design | 24V control coil | Compatible with R-410A system electrical loads | Heavy-duty silver alloy contact tips rated for high-cycle operation
• OEM vs Generic: OEM contactors like this HN51KC024 are built to Carrier's exact coil pull-in voltage and contact gap tolerances. Aftermarket contactors frequently use lower-grade contact alloys that pit faster under the high inrush current of a 4-ton compressor, leading to premature failure and potential compressor damage.
• Install difficulty: 3/5 — Always shut off power at both the disconnect box and the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter (to verify coil voltage and contact continuity). Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
