OEM Carrier 1-Pole 40 Amp 24V Contactor (HN51JD026) for Model PH13NB06000GABAA

This is the factory OEM replacement contactor for the Carrier PH13NB06000GABAA heat pump / condensing unit. The contactor is the high-voltage relay that closes the 240V power circuit to the compressor and condenser whenever the 24V control board sends a call for cooling or heating. When the contactor fails — due to burned or pitted contacts, a welded-shut coil, or a coil that no longer pulls in — you'll typically see one of three symptoms: the outdoor unit won't start at all, the compressor hums briefly and trips the breaker, or the system runs continuously and won't shut off. Replacing the contactor with an exact OEM unit restores factory-specified contact resistance and coil pull-in voltage, protecting both the compressor and condenser fan motor from voltage irregularities caused by worn aftermarket contacts.

• Specs: 1-Pole (SPST) | 40A FLA | 24V AC Coil (50/60 Hz) | Includes integrated shunt | Factory OEM part number HN51JD026
• OEM vs Generic: OEM contactors use factory-grade silver-alloy contacts rated to exact FLA specs. Generic contactors often use lower-grade contact materials that pit faster under inductive compressor loads, causing premature failure within 1–2 seasons.
• Install Difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. The integrated shunt must be transferred or matched on the replacement unit.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.

Compatibility: Direct OEM replacement for Carrier model PH13NB06000GABAA. Always verify the pole count, amperage (40A FLA), and coil voltage (24V) against the data plate on your unit before ordering.
