OEM Carrier 1-Pole 40 Amp Contactor (HN51JD026) for Model PH13NB06100GBBAA

This is the genuine OEM Carrier contactor (part number HN51JD026), factory-specified for the Carrier PH13NB06100GBBAA heat pump system. The contactor is a high-voltage relay that closes when your thermostat calls for cooling or heating, allowing 240V power to reach the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a stuck or welded plunger, or a burned coil — your system will either refuse to start entirely, run continuously without shutting off, or exhibit erratic short-cycling behavior.

• Specs: 1-Pole (SPST) | 40 FLA (Full Load Amps) | 24V AC Coil | 50/60 Hz | Includes shunt | Factory-matched OEM replacement
• OEM vs Generic: This OEM Carrier contactor features precision-machined contact surfaces and exact coil voltage tolerance. Generic contactors often use thinner contact material that pits faster under high cycling loads, leading to premature failure and potential compressor damage.
• Install difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. The contactor snaps into the existing bracket and re-uses original wiring.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before 3PM ship same business day from our warehouse.
