OEM Payne 2-Pole Contactor 24V Coil for Model PA12NA04200GABAA

This is the OEM factory-specified contactor (part number HN51KB024) for the Payne PA12NA04200GABAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or contacts welded shut — your system will either refuse to turn on entirely, run continuously without cycling off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp contact rating | Direct OEM replacement, part number HN51KB024 | Matches factory wiring terminals for drop-in installation
  • OEM vs Generic: OEM contactors use silver-alloy contacts rated for thousands of switching cycles. Generic substitutes frequently use lower-grade alloys that pit and weld prematurely, leading to repeat failures within a single cooling season.
  • Install difficulty: 2/5 — Disconnect power at the disconnect box AND the breaker panel before beginning. Tools needed: flathead 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. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Payne PA12NA04200GABAA split-system condenser. Always verify coil voltage (24V) and pole count against your unit's wiring diagram and data plate before ordering. Not sure it fits?

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA04200GABAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA04200GABAA. 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 PA12NA04200GABAA?
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.
