OEM Carrier 1-Pole Contactor 24V 30 Amp (HN51KC024) for Model PH14NA03600GBAAA

The Carrier HN51KC024 is the factory-specified OEM single-pole contactor for the Carrier PH14NA03600GBAAA heat pump. The contactor acts as a high-voltage relay, energized by the 24V control circuit to switch line-voltage power to the compressor. When a contactor fails, common symptoms include the outdoor unit failing to start, audible chattering or humming at the contactor coil, pitted or welded contacts causing the unit to run continuously, or the system not responding to thermostat calls at all.

  • Specs: 1-Pole | 24 VAC Coil | 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 the PH14NA03600GBAAA. Generic aftermarket contactors may carry looser amp tolerances and thinner contact surfaces, accelerating pitting and reducing service life — especially under high-cycling summer loads.
  • Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removal. Verify 24V coil pull-in with a thermostat call after installation.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH14NA03600GBAAA. Also cross-references part numbers HN51CC024, P282-0311, P282-1304, P282-1305, and 301362-101.

Frequently Asked Questions

Does this Contactor fit my Carrier PH14NA03600GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH14NA03600GBAAA. 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 PH14NA03600GBAAA?
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?
