OEM Payne 2-Pole Contactor HN51KC024 for Model PA12NA03600GAHAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA12NA03600GAHAA split-system air conditioner. The contactor is the high-voltage relay that closes when the thermostat calls for cooling, allowing 240V power to reach the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or contacts welded shut — the system will either fail to start entirely, run continuously without shutting off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V control coil | 30–40A load rating | Direct OEM replacement for part number HN51KC024 | Matched to factory specifications for the PA12NA03600GAHAA
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic alternatives often use lower-grade contacts that pit faster under the high in-rush current of a compressor start, leading to premature failure within one or two seasons.
  • Install difficulty: 2/5 — Always shut off power at the disconnect box and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed specifically for the Payne PA12NA03600GAHAA condenser unit. Cross-reference part number HN51KC024 against your unit's data plate and existing contactor label before ordering to confirm pole count, amperage, and coil voltage match. Our parts specialists are available to verify fitment — reach out before you order if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA03600GAHAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA03600GAHAA. 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 PA12NA03600GAHAA?
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?
