OEM Carrier 1-Pole 40 Amp Contactor (HN51JD026) for Model PH13NB060000ABAA

This is the factory OEM replacement contactor for the Carrier PH13NB060000ABAA heat pump system. The contactor is the high-voltage relay that connects and disconnects power to the compressor and/or condenser fan motor every time your thermostat calls for cooling or heating. When the contactor fails, the most common symptom is an air conditioning or heat pump system that simply will not turn on — the thermostat calls, the air handler responds, but the outdoor unit stays silent. Burned or pitted contacts and a stuck or welded contactor are the leading causes of no-cooling calls on residential heat pumps.

• Specs: 1-Pole (SPST) | 40 Amps | 24V AC Coil | With Shunt | 50/60 Hz | OEM Part Number HN51JD026
• OEM vs Generic: This is a genuine Carrier factory-authorized part engineered to exact contact gap, silver alloy composition, and coil pull-in voltage tolerances for the PH13NB060000ABAA. Generic contactors often use inferior contact materials that pit and oxidize faster, leading to repeat failures.
• Install Difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Discharge line-voltage terminals before handling.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed as a direct OEM drop-in replacement for the Carrier PH13NB060000ABAA heat pump condensing unit. Verify your existing contactor's pole count, amperage, and coil voltage against your unit's wiring diagram before ordering. Have questions about fitment?
