OEM Payne 2-Pole Contactor 24V Coil for Model PA3GNAA36000AA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA3GNAA36000AA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When a contactor fails — through pitted contacts, a burned coil, or a stuck plunger — the result is an outdoor unit that simply won't energize, even when the thermostat is calling for cooling.

  • Specs: 2-pole configuration | 24V control coil | 30A contact rating | Fits standard 3/8" mounting footprint | OEM part number HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to Payne's exact contact gap, coil pull-in voltage, and current rating. Generic contactors may use lower-grade silver-alloy contacts that pit faster under the high inrush current of a compressor start, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always shut off power at both the disconnect and breaker before beginning work. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Photograph all wiring before disconnecting. The contactor slides into the existing mounting bracket and reuses original wiring terminals.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Payne PA3GNAA36000AA 3-ton split-system condenser. Verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our parts specialists are available to confirm fitment — order with confidence and get your system cooling again today.

Frequently Asked Questions

Does this Contactor fit my Payne PA3GNAA36000AA?
Yes. This is the factory-specified OEM contactor for the Payne PA3GNAA36000AA. 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 PA3GNAA36000AA?
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?
