OEM Carrier 1-Pole 40 Amp 24V Contactor HN51JD026 for Model PH13NR06000GAAAA

This is the genuine OEM replacement contactor for the Carrier PH13NR06000GAAAA heat pump system. The contactor is the primary high-voltage switching relay in 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/or condenser fan motor. A failed contactor is one of the most common reasons an outdoor unit won't start: you may hear the indoor air handler running normally while the outdoor unit sits completely silent, or you may notice the contacts have welded shut, causing the system to run continuously without shutting off.

• Specs: 1-Pole (SPST) | 40 Amp FLA | 24V AC/DC Coil | 50/60 Hz | Includes integrated shunt | Factory OEM part number HN51JD026
• OEM vs Generic: This is a genuine Carrier factory part, precision-matched to the PH13NR06000GAAAA's electrical load specifications. Generic contactors may use lower-grade contact materials that pit and oxidize faster, leading to premature failure and potential compressor damage.
• Install Difficulty: 2/5 — Shut off power at both the disconnect box and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Discharge any capacitors in the unit before working near terminals.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct factory replacement for Carrier PH13NR06000GAAAA heat pump units.
