OEM Payne 2-Pole Contactor 24V Coil for Model PA12NA036000ABAA

This OEM replacement contactor (part number HN51KB024) is the factory-specified high-voltage relay for the Payne PA12NA036000ABAA split-system air conditioner. The contactor acts as the primary electrical switch between your thermostat's 24V control signal and the high-voltage power feeding the compressor and condenser fan motor. When the contactor fails — due to worn contacts, pitted terminals, or a stuck plunger — your system will appear dead, hum without starting, or run continuously without shutting off. Replacing a failed contactor is one of the most common and cost-effective AC repairs available.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp contact rating | Direct OEM replacement for part number HN51KB024 | Factory-matched to Payne PA12NA036000ABAA specifications
  • OEM vs Generic: This OEM contactor uses silver-alloy contacts rated to factory tolerance. Generic contactors often use lower-grade contact materials that pit and arc faster under load, leading to repeat failures within a single season.
  • Install difficulty: 2/5 — Always shut off power at the disconnect box and verify voltage is absent with a multimeter before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old unit. Transfer wires one at a time to the new contactor to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered for the Payne PA12NA036000ABAA 3-ton split-system condenser. Confirm coil voltage and pole configuration on your unit's wiring diagram or data plate before ordering. Our HVAC parts specialists are available to verify fitment — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA036000ABAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA036000ABAA. 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 PA12NA036000ABAA?
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?
