OEM Carrier 1-Pole 40 Amp 24V Contactor HN51JD026 for Model PH13NR060000AEAA

This is the factory OEM replacement contactor for the Carrier PH13NR060000AEAA heat pump system. The contactor is the high-voltage relay that acts as the main power switch for your outdoor unit — when your thermostat calls for cooling or heating, the 24V control circuit energizes the contactor coil, which closes the contacts and delivers line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an outdoor unit that hums but won't start, trips the breaker repeatedly, or simply does not respond when the system calls for a cycle.

• Specs: 1-Pole (SPST) | 40 Amp FLA | 24V AC Coil | 50/60 Hz | With shunt | OEM Part# HN51JD026
• OEM vs Generic: This is the genuine Carrier factory part, engineered to exact contact gap, coil pull-in voltage, and arc suppression specifications for the PH13NR060000AEAA. Aftermarket contactors may use lower-grade contact material that pits and burns faster under load, leading to early failure.
• Install Difficulty: 2/5 — Always disconnect power at the disconnect box and confirm voltage is absent with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removal. Swap wires one at a time to prevent miswiring.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
