OEM Payne 2-Pole Contactor 24V Coil for Model PA12NA024000ABAA

This OEM contactor (part number HN51KB024) is the factory-specified replacement for the Payne PA12NA024000ABAA split-system air conditioner. The contactor acts as the primary high-voltage relay in your condensing unit — when the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the high-voltage contacts that power the compressor and condenser fan motor. A failed contactor is one of the most common causes of an air conditioner that simply won't turn on, hums without starting, or runs continuously without cycling off due to welded contacts.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40A contact rating | Factory-matched contact material and coil resistance for reliable switching
  • OEM vs Generic: This OEM Payne contactor uses factory-grade silver-alloy contacts rated to exact amperage specifications. Generic aftermarket contactors often use lower-grade contact alloys that pit and weld prematurely, leading to repeat failures within a single cooling season.
  • Install Difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Line-voltage terminals must be properly torqued to prevent arcing.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3PM local time.

Compatibility: Designed and factory-matched for the Payne PA12NA024000ABAA split-system condenser. Verify coil voltage (24V) and pole configuration against your unit's wiring diagram and data plate before ordering. Not sure if this is the right part?

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA024000ABAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA024000ABAA. 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 PA12NA024000ABAA?
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?
