OEM Carrier Contactor 24V Coil 2-Pole for Model PH13NR024000ACAA

This is the factory OEM replacement contactor (part# HN51KC024) for the Carrier PH13NR024000ACAA heat pump / condenser unit. The contactor is the high-voltage switching relay that bridges 240V line power to your compressor and condenser fan motor every time your thermostat calls for cooling or heating. When a contactor fails — through pitted contacts, a burned coil, or a stuck plunger — the system will either fail to energize entirely, short-cycle, or trip the breaker repeatedly. Replacing a worn contactor is one of the most cost-effective repairs you can perform on a residential system.

• Specs: 2-pole design | 24V AC control coil | Rated for 240V load circuit | Factory-matched contact material and gap tolerances for Carrier PH13NR024000ACAA
• OEM vs Generic: OEM contactors use factory-grade silver-alloy contacts that resist pitting and arcing far longer than generic alternatives. Aftermarket units often use lower-grade contact surfaces that degrade faster under the high inrush current of a scroll compressor.
• Install difficulty: 2/5 — Shut off power at both the disconnect and the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify coil continuity. Always photograph existing wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
