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.

Frequently Asked Questions

Does this Contactor fit my Carrier PH14NB02400GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH14NB02400GBAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier PH14NB02400GBAAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
