OEM Carrier 1-Pole 40 Amp 24V Contactor HN51JD026 for Model PH15NB06000GBAAA

This is the genuine OEM Carrier contactor engineered as the factory-specified replacement for the Carrier PH15NB06000GBAAA heat pump system. The contactor is a high-voltage relay that closes the 240V power circuit to the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will not respond to thermostat calls, leaving you with a unit that hums but won't start, or one that is completely unresponsive at the outdoor cabinet.

• Specs: 1-Pole (SPST) | 40A FLA | 24V AC Coil | 50/60 Hz | Integrated shunt | Factory-matched contact ratings
• OEM vs Generic: This genuine Carrier OEM contactor (HN51JD026) uses factory-grade contact material and coil winding tolerances. Aftermarket contactors frequently use inferior silver-alloy contacts that pit faster under load, shortening service life — especially in high-cycle heat pump applications like the PH15NB06000GBAAA.
• Install difficulty: 2/5 — Always shut off power at both the disconnect and the breaker panel before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. The integrated shunt must be correctly positioned on reassembly.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships the same business day from our warehouse.
