OEM Carrier 1-Pole Contactor 24V 30A (HN51KC024) for Model PH13NR024000AEAA

This is the factory OEM replacement contactor for the Carrier PH13NR024000AEAA heat pump condenser. The contactor is the high-voltage relay that closes the compressor and condenser fan motor circuit every time your thermostat sends a 24V cooling call. When it fails — due to pitted contacts, a welded coil, or a burned coil — you'll typically find the outdoor unit completely unresponsive, humming without starting, or running continuously even with the thermostat off. Replacing the contactor is one of the most common and cost-effective field repairs in residential HVAC service.

• 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 the genuine Carrier Factory Authorized Part, engineered to exact contact gap, spring tension, and coil resistance specs for the PH13NR024000AEAA. Generic contactors can exhibit premature contact pitting and coil dropout at low voltage — risking compressor damage.
• Install Difficulty: 2/5 — Always disconnect power at both the disconnect box and the breaker before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify coil resistance and 24V pull-in after installation. Photograph all wiring before removing the old contactor.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
