OEM Carrier 1-Pole 40 Amp 24V Contactor HN51JD026 for Model PH13NR06000GAKAA

This is the genuine OEM Carrier contactor (part #HN51JD026) factory-specified for the Carrier PH13NR06000GAKAA heat pump system. The contactor is the high-voltage relay that bridges 240V power to the compressor and condenser fan motor every time your thermostat calls for cooling or heating. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed 24V coil — the system either won't respond to the thermostat at all, runs continuously without shutting off, or trips the breaker repeatedly. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs available.

• Specs: 1-Pole (SPST) | 40 Amp FLA | 24V AC coil voltage | 50/60 Hz | Includes integrated shunt | Factory-matched OEM tolerances
• OEM vs Generic: This genuine Carrier OEM contactor uses the same contact alloy, coil winding, and housing dimensions as the factory-installed unit. Generic contactors often use inferior contact materials that pit faster under high-cycle loads, shortening compressor life and causing nuisance callbacks.
• Install difficulty: 2/5 — Always shut off power at the disconnect box AND the breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Transfer wires one at a time to avoid miswiring.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
