OEM Payne 2-Pole Contactor 24V Coil for Model PA12NA036000AHAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA12NA036000AHAA split-system air conditioner. The contactor is the high-voltage relay responsible for switching power to the compressor and condenser fan motor when the thermostat calls for cooling. A failed contactor is one of the most common causes of an AC unit that won't turn on — symptoms include a system that hums but won't start, a compressor that stays off even with 24V signal present, or visible pitting and burning on the contact points.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40A rated contacts | Direct factory replacement for OEM part HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to Payne's exact electrical specifications, ensuring proper coil pull-in voltage and contact rating. Generic contactors may use lower-grade contact materials that arc, pit, and fail prematurely — especially in high-cycle summer conditions.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM EST.

Compatibility: Designed specifically for the Payne PA12NA036000AHAA 3-ton split-system condenser. Always verify coil voltage (24V) and pole configuration against your unit's data plate before ordering. Our parts specialists are available to confirm fitment — just reach out before you order. Ships fast so your customer stays cool.

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA036000AHAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA036000AHAA. 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 PA12NA036000AHAA?
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?
