OEM Payne 2-Pole Contactor 24V Coil for Model PA12NA02400GABAA

This OEM contactor (part number HN51KB024) is the factory-specified replacement for the Payne PA12NA02400GABAA split-system air conditioner. The contactor is a high-voltage relay controlled by a low-voltage (24V) signal from your thermostat. When the thermostat calls for cooling, the contactor closes and sends 240V power to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an air conditioner that won't start — symptoms include a system that clicks but never comes on, a compressor that hums without starting, or pitted/burned contact points visible on inspection.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30-40A rated | Factory-matched to Payne PA12NA02400GABAA electrical requirements | OEM part number HN51KB024
  • OEM vs Generic: This OEM contactor uses factory-grade contact materials rated for thousands of switching cycles. Generic contactors often use lower-grade alloys that pit and burn faster, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always shut off power at the disconnect box and confirm voltage is zero before beginning. 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. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed specifically for the Payne PA12NA02400GABAA split-system condenser. Verify pole count, amperage rating, and coil voltage on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA02400GABAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA02400GABAA. 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 PA12NA02400GABAA?
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?
