OEM Carrier 1-Pole Contactor 24V 30 Amp HN51KC024 for Model PH14NB03600GABAA

This is the factory-authorized OEM replacement contactor for the Carrier PH14NB03600GABAA heat pump condenser. The contactor is a high-voltage relay controlled by a 24V signal from the thermostat — when the thermostat calls for cooling or heating, the contactor closes and sends line voltage to the compressor and condenser fan motor. When it fails, symptoms include the outdoor unit not turning on at all, audible chattering or humming at the contactor, the unit running continuously and not shutting off, or visible pitting and burning on the contact surfaces.

  • Specs: 1-Pole configuration | 24 VAC coil voltage | 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 your unit. Generic aftermarket contactors may differ in coil pull-in voltage tolerance, contact material, and terminal layout — all of which can cause nuisance lockouts or premature failure under high-cycling summer loads.
  • Install difficulty: 2/5 — Shut off power at both the disconnect and the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Verify 24V coil pull-in after installation with a thermostat call before closing the unit.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
