OEM Payne 2-Pole Contactor 24V Coil for Model PA13NAZ24000AAAA

This OEM replacement contactor (part number HN51KB024) is the factory-specified high-voltage relay for the Payne PA13NAZ24000AAAA split-system air conditioner. The contactor acts as the critical switching device between your 24V thermostat signal and the high-voltage power supply to both the compressor and condenser fan motor. When the contactor fails, the most common symptoms include the AC unit failing to turn on at all, the compressor not starting despite the thermostat calling for cooling, chattering or buzzing from the electrical panel inside the condenser, or visible pitting and burning on the contactor's contact points.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage matched to PA13NAZ24000AAAA | OEM part number HN51KB024 | Meets original factory electrical specifications
  • OEM vs Generic: This OEM contactor is manufactured to exact Payne/Carrier factory tolerances. Generic contactors often use lower-grade contact materials that pit and corrode faster under load, leading to premature failure and potential compressor damage — especially in humid or coastal climates.
  • Install difficulty: 2/5 — Shut off all power at the disconnect box and breaker before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Always photograph existing wiring before removing the old contactor to ensure correct terminal reconnection.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed specifically for the Payne PA13NAZ24000AAAA 2-ton single-stage split-system air conditioner. Verify coil voltage (24V) and pole configuration on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment before you purchase — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA13NAZ24000AAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA13NAZ24000AAAA. 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 PA13NAZ24000AAAA?
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?
