OEM Payne 2-Pole Contactor for Model PA13NA0240NGAFAA — Part HN51KC024

This is the factory-specified OEM contactor (part HN51KC024) for the Payne PA13NA0240NGAFAA 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 240V power to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a welded coil, or a burned-out coil — the outdoor unit will not energize at all, or may run continuously without responding to thermostat commands. This is one of the most common failure points on any split-system condenser and a straightforward DIY or service technician replacement.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40A contact rating | Direct OEM replacement for part number HN51KC024 | Factory-matched contact material for full rated service life
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated to factory tolerances. Generic contactors frequently use lower-grade contact materials that pit and fail faster — especially under the high inrush current of a compressor start. For a component this critical, OEM is the recommended choice.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdriver, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Photograph all wiring connections before disconnecting. Label each wire to its terminal for reassembly.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: Designed as a direct OEM drop-in replacement for the Payne PA13NA0240NGAFAA 2-ton single-stage R-410A split-system condenser. Confirm your existing contactor is a 2-pole, 24V coil unit by checking the data label on the contactor body before ordering. Have questions about fitment? Our HVAC parts specialists verify compatibility before you buy — reach out before placing your order.

Frequently Asked Questions

Does this Contactor fit my Payne PA13NA0240NGAFAA?
Yes. This is the factory-specified OEM contactor for the Payne PA13NA0240NGAFAA. 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 PA13NA0240NGAFAA?
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?
