OEM Carrier Single-Pole Contactor 30A 24V Coil (HN51KC024) for Model PH14NB02400GBAAA

This is the genuine OEM factory-specified contactor for the Carrier PH14NB02400GBAAA heat pump. The contactor is the high-voltage switching relay that connects line-voltage power to the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. When it fails, symptoms include the outdoor unit refusing to start, audible chattering or humming from the control box, pitted or fused contacts keeping the unit locked on, or a complete loss of cooling and heating capacity.

  • Specs: 1-Pole configuration | 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 contactor meets exact Carrier engineering tolerances for contact gap, coil pull-in voltage, and arc suppression. Generic contactors may use thinner contact pads that pit and weld faster under high-cycle residential loads, shortening system life.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box AND the breaker before opening the control panel. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removing any terminals. Verify 24V coil pull-in after installation with a thermostat call.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH14NB02400GBAAA. Also cross-references to P282-0311, HN51CC024, HN51KB024, P282-1304, P282-1305, and P282-1308. Verify your unit's data plate and wiring diagram before ordering. Our team is available to confirm fitment prior to purchase.
