OEM Carrier Contactor 2-Pole 24V Coil for Model PH13NR02400GAEAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Carrier PH13NR02400GAEAA heat pump / condensing unit. The contactor is a high-voltage relay that acts as the main switching device in your outdoor unit — when the thermostat calls for cooling or heating, the 24V control board energizes the contactor coil, which closes the high-voltage contacts and powers the compressor and condenser fan motor. A failed contactor is one of the most common causes of an outdoor unit that refuses to start, hums without running, or trips the breaker intermittently.

  • Specs: 2-Pole design | 24V coil voltage | Factory-matched contact rating | Exact OEM form, fit, and function for Carrier PH13NR02400GAEAA
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact coil pull-in voltage and contact ampacity specifications. Aftermarket contactors often use lower-grade contact materials that pit and arc faster, shortening service life significantly in high-cycle applications.
  • Install difficulty: 3/5 — Always disconnect power at both the outdoor disconnect and the breaker panel before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Verify coil voltage (24V) with a multimeter before installing.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed and verified for Carrier model PH13NR02400GAEAA. Always confirm the part number on your existing contactor's label and cross-reference your unit's data plate voltage and amperage ratings before ordering. Our HVAC parts specialists are available to verify fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR02400GAEAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR02400GAEAA. 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 PH13NR02400GAEAA?
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?
