OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil — HN51KC024 for Model PH13NR01800GACAA

This is the genuine OEM Carrier contactor (part# HN51KC024) factory-specified for the Carrier PH13NR01800GACAA heat pump condenser. The contactor is the high-voltage switching relay that connects and disconnects line voltage to the compressor every time your thermostat calls for cooling or heating. When the contactor fails — through pitted or welded contacts, a burnt coil, or simply normal wear — the system will either refuse to start, hum without cooling, run continuously with no thermostat call, or trip a breaker. Replacing it promptly prevents compressor damage and restores reliable operation.

• Specs: 1-Pole | 30A FLA / 150A LRA | 24 VAC Coil | 50/60 Hz | Factory OEM Part# HN51KC024
• OEM vs Generic: OEM contactors are manufactured to Carrier's exact electrical and mechanical tolerances. Generic contactors may use lower-grade contact materials prone to faster pitting, arcing, and premature welding — especially under the high inrush loads of a heat pump compressor.
• Install difficulty: 2/5 — Always disconnect and lock out all power before servicing. Photograph existing wiring before removing any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, non-contact voltage tester. Verify 24V coil pull-in after installation with a thermostat call.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
