OEM Carrier 2-Pole Contactor 24V Coil for Model HP13NR02400GAKAA

This is the factory-specified OEM contactor (part number HN51KC024) for the Carrier HP13NR02400GAKAA heat pump condenser. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the thermostat calls for cooling or heating, the contactor closes to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons a heat pump stops responding: symptoms include the outdoor unit not energizing at all, audible chattering or buzzing at the contactor, pitted or burned contacts, or the unit running continuously without shutting off.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40A contact rating | Heavy-duty silver-alloy contact tips | Factory-matched to Carrier HP13NR series
  • OEM vs Generic: This OEM HN51KC024 contactor meets Carrier's exact coil pull-in voltage, contact gap, and amp rating specifications. Generic contactors often use lower-grade contact materials that pit and weld faster under the high inrush current of a compressor start, leading to premature failure or a stuck-closed condition.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify voltage is absent with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier HP13NR02400GAKAA 2-ton heat pump condenser. Verify coil voltage (24V) and pole count on your existing contactor's data label before ordering. Our fitment team is available to confirm compatibility before you buy — ships same day when ordered before 3 PM.

Frequently Asked Questions

Does this Contactor fit my Carrier HP13NR02400GAKAA?
Yes. This is the factory-specified OEM contactor for the Carrier HP13NR02400GAKAA. 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 HP13NR02400GAKAA?
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?
