OEM Payne 2-Pole Contactor 24V Coil for Model PA3ZNB030000AB

This OEM replacement contactor (part number HN51KC024) is the factory-specified high-voltage relay for the Payne PA3ZNB030000AB split-system air conditioner. The contactor acts as the primary switching device that allows 240V power to flow to the compressor and condenser fan motor when your thermostat calls for cooling. When the contactor fails — whether due to worn contacts, pitted surfaces, or a burned coil — your system will either refuse to start entirely, run continuously without shutting off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V AC coil | Factory-rated amperage for 2.5-ton residential condensers | Replaces OEM part number HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to exact Payne/Carrier factory specifications, ensuring proper coil pull-in voltage and contact surface durability. Generic contactors may use inferior contact materials that pit and fail prematurely under load cycling.
  • Install difficulty: 3/5 — Requires shutting off power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a phone or camera to photograph existing wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed for the Payne PA3ZNB030000AB single-stage split-system condenser. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before your order ships — no guesswork, no returns hassle.

Frequently Asked Questions

Does this Contactor fit my Payne PA3ZNB030000AB?
Yes. This is the factory-specified OEM contactor for the Payne PA3ZNB030000AB. 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 PA3ZNB030000AB?
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?
