OEM Carrier Contactor 2-Pole 24V Coil for Model PH14NA02400GAAAA

This OEM contactor (part number HN51KC024) is the factory-specified high-voltage switching relay for the Carrier PH14NA02400GAAAA heat pump condenser. The contactor acts as the main power switch between your electrical panel and the compressor and condenser fan motor — controlled by a low-voltage (24V) signal from your thermostat. When the contactor fails, the most common symptoms include an outdoor unit that won't energize at all, a buzzing or chattering noise from the contactor coil, pitted or burnt contact points, or a unit that runs continuously and won't shut off.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier PH14NA02400GAAAA | Heavy-duty silver-alloy contact points rated for high-cycle operation
  • OEM vs Generic: This is a genuine OEM Carrier contactor manufactured to exact factory tolerances. Generic aftermarket contactors may use thinner contact material that pits prematurely, leading to repeat failures, compressor damage, or nuisance lockouts.
  • Install difficulty: 3/5 — Always shut off power at both the breaker panel and the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter to verify coil resistance and contact continuity. Photograph all wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM drop-in replacement for the Carrier PH14NA02400GAAAA heat pump. Always verify coil voltage and pole configuration against your unit's data plate before ordering. Our technical team is available to confirm fitment — order with confidence and get back to comfort fast.

Frequently Asked Questions

Does this Contactor fit my Carrier PH14NA02400GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH14NA02400GAAAA. 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 PH14NA02400GAAAA?
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.
