OEM Payne 2-Pole Contactor HN51KC024 for Model PA10JA047000ACAA

This is the factory-specified OEM contactor (part number HN51KC024) for the Payne PA10JA047000ACAA split-system air conditioner. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and switches line voltage to the compressor and condenser fan motor. When the contactor fails — whether from pitted contacts, a stuck plunger, or a burned coil — the result is an AC system that won't start, runs continuously without shutting off, or trips the breaker repeatedly.

  • Specs: 2-pole configuration | 24V coil voltage | Rated for line-voltage switching | OEM part number HN51KC024 | Direct factory replacement for Payne PA10JA047000ACAA
  • OEM vs Generic: OEM contactors are manufactured to exact Payne/Carrier specifications with precise contact gap tolerances and coil pull-in voltage ratings. Generic contactors may use inferior contact materials that arc and pit faster, leading to repeat failures within a single cooling season.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify voltage is absent with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct re-termination.
  • 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 PA10JA047000ACAA split-system condenser. Verify your existing contactor's pole count and coil voltage against your unit's data plate before ordering. If you need help confirming fitment, our HVAC parts specialists are available to verify compatibility before you buy — same-day shipping on all in-stock orders.

Frequently Asked Questions

Does this Contactor fit my Payne PA10JA047000ACAA?
Yes. This is the factory-specified OEM contactor for the Payne PA10JA047000ACAA. 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 PA10JA047000ACAA?
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?
