OEM Carrier 1-Pole Contactor 30A 24V Coil (HN51KC024) for Model PH13NB036000ABAA

This is the genuine OEM replacement contactor for the Carrier PH13NB036000ABAA heat pump. The contactor is the high-voltage relay that bridges your 24V control circuit to the high-voltage compressor and condenser fan motor circuit. When your thermostat sends a cooling call, the 24V coil energizes and the contactor closes, allowing line voltage to power the compressor. When this part fails, you'll typically experience a complete no-start condition — the outdoor unit sits silent even though the thermostat is calling for cooling — or you may hear a buzzing or chattering sound as burned or pitted contacts fail to close properly.

• Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil Voltage | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This factory-authorized OEM contactor is built to exact Carrier specifications for contact material, coil pull-in voltage, and mechanical travel — ensuring reliable pull-in even at low 24V conditions. Generic contactors often use inferior contact alloys that pit prematurely under compressor LRA loads, leading to repeat failures within one or two seasons.
• Install Difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before touching any terminals. Photograph all wiring before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Verify contactor pull-in with a 24V call from the thermostat after installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
