OEM Carrier 1-Pole Contactor 24V 30A (HN51KC024) for Model PH13NR024000AEAA

This is the factory OEM replacement contactor for the Carrier PH13NR024000AEAA heat pump condenser. The contactor is the high-voltage relay that closes the compressor and condenser fan motor circuit every time your thermostat sends a 24V cooling call. When it fails — due to pitted contacts, a welded coil, or a burned coil — you'll typically find the outdoor unit completely unresponsive, humming without starting, or running continuously even with the thermostat off. Replacing the contactor is one of the most common and cost-effective field repairs in residential HVAC service.

  • Specs: 1-Pole | 24 VAC Coil | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50/60 Hz | OEM Part# HN51KC024
  • OEM vs Generic: This is the genuine Carrier Factory Authorized Part, engineered to exact contact gap, spring tension, and coil resistance specs for the PH13NR024000AEAA. Generic contactors can exhibit premature contact pitting and coil dropout at low voltage — risking compressor damage.
  • Install Difficulty: 2/5 — Always disconnect power at both the disconnect box and the breaker before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify coil resistance and 24V pull-in after installation. Photograph all wiring before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PH13NR024000AEAA heat pump condensers. Also commonly used on Bryant, Payne, and other Carrier-platform equipment specifying part HN51KC024. Always verify the part number against your unit's data plate or parts list before ordering. Our team is available to confirm fitment — contact us before you order.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR024000AEAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR024000AEAA. 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 PH13NR024000AEAA?
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?
