OEM Carrier 1-Pole Contactor 30 Amp 24V Coil for Model PH10JA036000AGAA (HN51KC024)

This OEM Carrier contactor (part# HN51KC024) is the factory-specified replacement for the Carrier PH10JA036000AGAA heat pump unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to deliver line voltage to the compressor and condenser fan motor. When the contactor fails, the system may refuse to start, run continuously without shutting off, produce audible chattering or humming from the electrical panel, or show visible pitting and burning on the contact surfaces. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs available.

  • Specs: 1-Pole configuration | 24 VAC coil voltage | 30 Amp FLA (Full Load Amps) | 150 Amp LRA (Locked Rotor Amps) | 50/60 Hz | Factory OEM part number HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact OEM specifications. Generic aftermarket contactors may carry wider coil voltage tolerances and lighter-duty contact ratings, increasing the risk of premature failure under heavy compressor 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 connections before removing the old contactor. Verify 24V coil pull-in after installation before closing the panel.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH10JA036000AGAA heat pump system. Also cross-references part numbers HN51CC024, P282-0311, P282-1304, P282-1305, 301362-101, and 301323-101.

Frequently Asked Questions

Does this Contactor fit my Carrier PH10JA036000AGAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH10JA036000AGAA. 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 PH10JA036000AGAA?
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?
