OEM Carrier 1-Pole 40 Amp 24V Contactor HN51JD026 for Model PH13NR06000GACAA

This is the genuine OEM Carrier replacement contactor for the PH13NR06000GACAA heat pump system. The contactor is the high-voltage switching relay that allows the low-voltage thermostat signal (24V) to energize the compressor circuit. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — your system will either fail to turn on entirely, run continuously without cycling off, or trip the breaker. Replacing it with the correct OEM part restores factory-specified switching performance and protects your compressor investment.

• Specs: 1-Pole (SPST) | 40A FLA (Full Load Amps) | 24V AC Coil | 50/60 Hz | Includes integrated shunt | OEM Part # HN51JD026
• OEM vs Generic: This is the factory-matched OEM contactor. Generic contactors often use lighter-gauge contact material rated for fewer switching cycles, increasing the risk of premature failure and compressor damage during peak cooling season.
• Install difficulty: 2/5 — Always disconnect power at the breaker and discharge any capacitors before servicing. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify coil voltage. Photograph all wiring connections before removing the old contactor.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
