OEM Carrier Contactor 2-Pole 24V Coil for Model PH13NR02400GAEAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Carrier PH13NR02400GAEAA heat pump / condensing unit. The contactor is a high-voltage relay that acts as the main switching device in your outdoor unit — when the thermostat calls for cooling or heating, the 24V control board energizes the contactor coil, which closes the high-voltage contacts and powers the compressor and condenser fan motor. A failed contactor is one of the most common causes of an outdoor unit that refuses to start, hums without running, or trips the breaker intermittently.

• Specs: 2-Pole design | 24V coil voltage | Factory-matched contact rating | Exact OEM form, fit, and function for Carrier PH13NR02400GAEAA
• OEM vs Generic: This OEM contactor is manufactured to Carrier's exact coil pull-in voltage and contact ampacity specifications. Aftermarket contactors often use lower-grade contact materials that pit and arc faster, shortening service life significantly in high-cycle applications.
• Install difficulty: 3/5 — Always disconnect power at both the outdoor disconnect and the breaker panel before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Verify coil voltage (24V) with a multimeter before installing.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
