OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil — HN51KC024 for Model PH13NB03100GAAAA

This is the factory-specified OEM replacement contactor for the Carrier PH13NB03100GAAAA heat pump system. The contactor is the high-voltage relay that closes the circuit to power the compressor and/or condenser fan motor every time your thermostat sends a cooling or heating call. When the contactor fails — through pitted or burned contacts, a welded-open coil, or a coil that won't pull in — your outdoor unit simply will not start, leaving you with no cooling or heating despite the thermostat calling. This is one of the most frequently replaced components in any residential HVAC system.

  • Specs: 1-Pole (single-pole) | 30A FLA / 150A LRA | 24 VAC coil | 50/60 Hz | OEM Part # HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact factory tolerances for the PH13NB03100GAAAA. Generic contactors may vary in coil pull-in voltage and contact silver-alloy quality, leading to premature failure in high-cycle residential applications.
  • Install difficulty: 2/5 — Shut off power at the disconnect box and the breaker panel before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in with a meter after installation.
  • Warranty: 1-year OEM factory warranty. In-stock and ships the same business day from our warehouse.

Compatibility: Factory-matched for Carrier model PH13NB03100GAAAA. Cross-references include P282-0311, HN51CC024, 301362-101, and 301323-101. Always verify your unit's wiring diagram and data plate before ordering. Our fitment team is available to confirm compatibility before you buy — order with confidence and get your system back online today.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NB03100GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NB03100GAAAA. 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 PH13NB03100GAAAA?
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?
