OEM Carrier 1-Pole 40 Amp 24V Contactor for Model PH13NR060000AFAA — Part# HN51JD026

This OEM contactor is the factory-specified replacement for the Carrier PH13NR060000AFAA heat pump system. The contactor is the high-voltage switching relay that receives a 24V signal from the thermostat and closes to supply line voltage to the compressor. When a contactor fails — whether due to pitted contacts, a burned coil, or a stuck plunger — the most common symptoms are an AC or heat pump that won't start at all, a compressor that hums but never engages, or a unit that runs continuously without shutting off.

• Specs: 1 Pole (SPST) | 40 FLA (Full Load Amps) | 24V AC Coil | 50/60 Hz | Includes integrated shunt | Factory OEM part number HN51JD026
• OEM vs Generic: This is a genuine Carrier OEM contactor built to exact factory tolerances. Generic aftermarket contactors may carry mismatched amp ratings or coil sensitivities that lead to premature failure or nuisance tripping, shortening the life of your compressor.
• Install Difficulty: 2/5 — Always disconnect power at the disconnect box and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify coil continuity. Photograph all wire connections before removing the old unit.
• Warranty & Shipping: Backed by Carrier's 1-year OEM parts warranty. Orders ship same business day from our warehouse — your repair won't wait.
