OEM Carrier 1-Pole Contactor 24V 30 Amp (HN51KC024) for Model PH14NA03600GBAAA

The Carrier HN51KC024 is the factory-specified OEM single-pole contactor for the Carrier PH14NA03600GBAAA heat pump. The contactor acts as a high-voltage relay, energized by the 24V control circuit to switch line-voltage power to the compressor. When a contactor fails, common symptoms include the outdoor unit failing to start, audible chattering or humming at the contactor coil, pitted or welded contacts causing the unit to run continuously, or the system not responding to thermostat calls at all.

• Specs: 1-Pole | 24 VAC Coil | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50/60 Hz | OEM Part # HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact specifications for the PH14NA03600GBAAA. Generic aftermarket contactors may carry looser amp tolerances and thinner contact surfaces, accelerating pitting and reducing service life — especially under high-cycling summer loads.
• Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removal. Verify 24V coil pull-in with a thermostat call after installation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
