OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil — Model PH15NA02400GBAAA

This is the factory OEM replacement contactor for the Carrier PH15NA02400GBAAA heat pump. The contactor is the high-voltage switching relay that closes when the 24V thermostat signal calls for cooling or heating, energizing the compressor and condenser fan motor. When it fails — whether from pitted contacts, a burnt coil, or welded-shut contacts — your system will either refuse to start or run continuously without responding to the thermostat. Part number HN51KC024 is the Carrier Factory Authorized replacement, engineered to meet exact OEM specifications for this unit.

  • Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil Voltage | 50/60 Hz | Screw-terminal line/load connections
  • OEM vs Generic: OEM Carrier contactors use factory-spec contact material and coil windings matched to the PH15NA02400GBAAA's control circuit. Generic contactors often use softer contact alloys that pit and weld faster under high-cycle residential use, leading to repeat failures within a single cooling season.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before opening the control panel. Photograph all wiring before removing the old contactor. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V coil signal). Note: low-voltage coil leads may be on opposite sides of the new contactor versus the original — confirm with your unit's wiring diagram.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — in stock and ready to go.

Compatibility: Verified fit for Carrier model PH15NA02400GBAAA heat pump. Also cross-references to P282-0311, HN51CC024, P282-1304, P282-1305, and additional legacy part numbers. Always confirm the part number against your unit's data plate or parts list before ordering. Have a question about fitment?

Frequently Asked Questions

Does this Contactor fit my Carrier PH15NA02400GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH15NA02400GBAAA. 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 PH15NA02400GBAAA?
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?
