OEM Payne 2-Pole Contactor 24V Coil (HN51KC024) for Model PA12NA04800GACAA

This is the factory OEM replacement contactor for the Payne PA12NA04800GACAA split-system air conditioner. The contactor is the high-voltage relay responsible for switching power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — the outdoor unit will not energize at all, or may run continuously without cycling off. OEM part number HN51KC024 is the exact factory-specified replacement, ensuring proper fit and reliable operation.

  • Specs: 2-pole configuration | 24V AC control coil | Rated for high-amperage compressor loads | Direct OEM replacement — part number HN51KC024
  • OEM vs Generic: OEM contactors use factory-grade silver-alloy contact tips rated for thousands of switching cycles. Generic alternatives often use inferior contact materials that pit and weld prematurely, leading to repeat failures and potential compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and breaker before servicing. Tools needed: flat-head and Phillips screwdrivers, 1/4" nut driver, 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. Ships same business day from our stocked warehouse — order by 3 PM local time for same-day dispatch.

Compatibility: This contactor is the factory-specified replacement for the Payne PA12NA04800GACAA split-system air conditioner (4-ton, R-410A). Verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you buy if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA04800GACAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA04800GACAA. 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 PA12NA04800GACAA?
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.
