OEM Carrier 1-Pole 30 Amp Contactor HN51KC024 for Model PH16NA02400GBBAA

This is the factory OEM contactor for the Carrier PH16NA02400GBBAA heat pump. The contactor is the high-voltage switching relay that closes when the thermostat sends a 24V signal, connecting line voltage to the compressor and/or condenser fan motor. When it fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your outdoor unit will not energize at all, or may run continuously without shutting off. Replacing the contactor is one of the most common and cost-effective HVAC repairs available.

  • 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 is a genuine Carrier Factory Authorized Part, manufactured to exact factory tolerances. Generic contactors may use thinner contact material that pits faster under compressor load cycling, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter. Photograph all wiring before disconnecting terminals. Verify 24V coil pull-in with a meter after installation before restoring power.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH16NA02400GBBAA heat pump. Also cross-references to P282-0311, HN51CC024, P282-1304, P282-1305, and other part numbers — verify against your unit's wiring diagram and parts list before ordering.

Frequently Asked Questions

Does this Contactor fit my Carrier PH16NA02400GBBAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH16NA02400GBBAA. 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 PH16NA02400GBBAA?
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?
