OEM Payne 2-Pole Contactor 24V Coil for Model PA1ZNA030000ABAA

This is the factory OEM replacement contactor (part number HN51KB024) for the Payne PA1ZNA030000ABAA split-system air conditioner. The contactor is the high-voltage relay that bridges your thermostat's low-voltage signal to the high-voltage power circuit, energizing the compressor and condenser fan motor every time a cooling call is made. When the contactor fails — due to worn or pitted contacts, a burned coil, or contacts that weld shut — your system may refuse to start, run continuously without shutting off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched contact amperage rating | Heavy-duty silver-alloy contact tips for reduced arcing and extended service life
  • OEM vs Generic: The OEM HN51KB024 contactor meets Payne's exact electrical specifications and contact gap tolerances. Generic contactors frequently use lower-grade contact materials that pit and fail sooner, especially in high-cycle Southern climates.
  • Install difficulty: 2/5 — Always shut off power at both 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 removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM local time ship same business day from our climate-controlled warehouse.

Compatibility: Designed as a direct OEM replacement for the Payne PA1ZNA030000ABAA condensing unit. Verify coil voltage (24V) and pole configuration on your unit's data plate before ordering. Not sure if this is the right part? Our HVAC parts specialists confirm fitment before every order — just reach out before you buy.

Frequently Asked Questions

Does this Contactor fit my Payne PA1ZNA030000ABAA?
Yes. This is the factory-specified OEM contactor for the Payne PA1ZNA030000ABAA. 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 PA1ZNA030000ABAA?
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?
