OEM Carrier 1-Pole 40 Amp 24V Contactor HN51JD026 for Model PH13NR06000GAFAA

This is the factory OEM replacement contactor for the Carrier PH13NR06000GAFAA heat pump system. The contactor is the high-voltage relay that closes the 240V circuit to the compressor and condenser fan every time the thermostat calls for cooling or heating. When the contactor fails — due to pitted contacts, a burned coil, or a welded-shut set of points — your system will either refuse to start, run continuously without stopping, or trip the breaker. Replacing a worn contactor is one of the highest-impact, lowest-cost repairs in HVAC service.

• Specs: 1-Pole (SPST) | 40 Amp FLA | 24V AC Coil | 50/60 Hz | Integrated shunt | Factory OEM part number HN51JD026
• OEM vs Generic: This OEM contactor uses factory-spec contact materials and coil windings matched to Carrier's design tolerances. Generic contactors may use thinner contact pads that pit faster under the high inrush current of a 5-ton compressor load, shortening service life significantly.
• Install difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Swap wires one at a time to avoid miswiring. Verify coil voltage reads ~24V AC at the contactor terminals before declaring a repair complete.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model PH13NR06000GAFAA.
