OEM Payne 2-Pole Contactor HN51KC024 for Model PA14NA02400GAAAA

This is the factory-specified OEM contactor (part number HN51KC024) for the Payne PA14NA02400GAAAA split-system air conditioner. The contactor is a high-voltage relay controlled by the 24V signal from your thermostat. When the thermostat calls for cooling, the contactor closes and sends line voltage to both the compressor and condenser fan motor. A failed contactor is one of the most common reasons an AC unit stops responding — symptoms include the system not turning on at all, the compressor dropping out mid-cycle, or visible pitting and burning on the contact points.

  • Specs: 2-pole configuration | 24V AC coil | 30-amp rated contacts | Direct OEM replacement — part number HN51KC024 | Factory-matched to Payne PA14NA02400GAAAA
  • OEM vs Generic: OEM contactors use silver-alloy contact tips and precision coil windings matched to factory specifications. Generic contactors often use lower-grade contact materials that pit and weld faster under high-cycling summer loads, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always shut off power at the disconnect box and verify voltage is absent with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Payne PA14NA02400GAAAA 2-ton split-system air conditioner. Cross-references OEM part number HN51KC024. Confirm coil voltage (24V) and pole count on your unit's data plate before ordering. Need fitment verification? Our HVAC parts specialists confirm compatibility before your order ships — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA14NA02400GAAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA14NA02400GAAAA. 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 Payne PA14NA02400GAAAA?
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 Payne 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 Payne 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?
