OEM Carrier 2-Pole Contactor HN51KC024 for Model PH13NB03600GABAA

This is the genuine OEM replacement contactor for the Carrier PH13NB03600GABAA heat pump / split-system condenser. The contactor is a high-voltage relay controlled by your thermostat's 24V signal. When the thermostat calls for cooling or heating, the 24V coil energizes and closes the contactor's power poles, sending line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons a condensing unit will not start — symptoms include the thermostat calling for cooling but the outdoor unit remaining completely silent, humming without engaging, or pitting and burning on the contact points visible on inspection.

  • Specs: 2-Pole design | 24V AC coil voltage | Factory-matched contact rating | OEM Part Number HN51KC024
  • OEM vs Generic: This genuine Carrier OEM contactor uses factory-spec silver-alloy contact points rated for the exact load of the PH13NB03600GABAA. Generic contactors often use lower-grade contacts that pit and fail faster under high-cycle conditions, shortening system lifespan.
  • Install Difficulty: 2/5 — Always shut off power at the disconnect box AND the breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as the factory-specified contactor for Carrier model PH13NB03600GABAA. Always verify coil voltage and pole count against your unit's wiring diagram or data plate before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — same-day shipping available on all in-stock orders.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NB03600GABAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NB03600GABAA. 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 PH13NB03600GABAA?
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?
