OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil — HN51KC024 for Model PH13NA01800GABAA

This is the genuine OEM Carrier contactor (part# HN51KC024), factory-specified for the Carrier PH13NA01800GABAA heat pump condensing unit. The contactor is the primary high-voltage switching relay in your outdoor unit — when the 24V thermostat signal calls for cooling or heating, the contactor coil energizes and closes the power circuit to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an AC or heat pump that won't start, hums without running, chatters repeatedly, or — when contacts weld shut — runs continuously and won't shut off.

  • Specs: 1-Pole (single-pole) | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | Factory part# HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact contact gap, coil pull-in voltage, and arc-suppression specifications. Generic contactors often use lower-grade contact materials that pit and weld faster under compressor inrush loads, shortening service life significantly.
  • Install difficulty: 2/5 — Shut off power at the disconnect and verify zero voltage with a multimeter before touching any wiring. Photograph all wire connections before removal. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, multimeter. Swap wires one at a time to avoid miswiring the 24V coil leads.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NA01800GABAA heat pump condensing unit. Cross-references include P282-0311, HN51CC024, 301362-101, and 301323-101. Always verify your unit's data plate and wiring diagram before ordering — questions? Our parts team confirms fitment before you buy.
