OEM Carrier 1-Pole 40 Amp Contactor HN51JD026 for Model PH13NA06000GABAA

This is the genuine OEM Carrier contactor (part number HN51JD026), the factory-specified high-voltage relay for the Carrier PH13NA06000GABAA split-system heat pump. The contactor acts as the main power switch between the thermostat's 24V control signal and the high-voltage compressor and condenser fan circuit. When the thermostat calls for cooling or heating, the 24V coil energizes and pulls in the contactor's pole, allowing line voltage to reach the compressor. When a contactor fails, symptoms include the outdoor unit not turning on at all, the unit running continuously without shutting off, audible chattering or buzzing at the contactor, or visible pitting and burning on the contact points. Replacing a worn contactor promptly protects the compressor from damage caused by arcing and voltage irregularities.

• Specs: 1-Pole | 40 Amp | 24V AC Coil | SPST Normally Open | Includes shunt | 50/60 Hz compatible
• OEM vs Generic: This genuine Carrier OEM part is built to exact factory tolerances, ensuring proper coil pull-in voltage, contact rating, and long-term reliability. Generic contactors may use lower-grade contact materials that arc and pit faster, shortening compressor life.
• Install difficulty: 2/5 — Always shut off power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Transfer one wire at a time to avoid miswiring.
