OEM Carrier 1-Pole Contactor 30 Amp 24V Coil for Model PH10JA03600GAEAA — Part# HN51KC024

This is the genuine OEM factory-specified contactor for the Carrier PH10JA03600GAEAA heat pump unit. The contactor is the high-voltage switching relay that completes the power circuit to your compressor and condenser fan motor every time the thermostat calls for cooling or heating. When the 24V control circuit energizes the coil, the contacts close and line voltage flows to the load. A failed contactor is one of the most common causes of an HVAC system that won't start, won't shut off, or makes a persistent chattering or humming noise from the condenser cabinet.

  • 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, built to exact factory tolerances for contact gap, coil pull-in voltage, and arc suppression. Generic contactors often use lower-grade contact materials that pit faster, shortening compressor life and increasing nuisance callbacks.
  • Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before opening the unit. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Swap wires one-at-a-time to avoid miswiring the 24V coil leads.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH10JA03600GAEAA. Verify your unit's wiring diagram and confirm the 1-pole, 30A, 24V coil specification matches your existing contactor's data tag before ordering. Not sure it fits?

Frequently Asked Questions

Does this Contactor fit my Carrier PH10JA03600GAEAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH10JA03600GAEAA. 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 PH10JA03600GAEAA?
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?
