OEM Payne 2-Pole Contactor 24V Coil HN51KC024 for Model PA10JA04700GACAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA10JA04700GACAA split-system air conditioner. The contactor is the 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 the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the outdoor unit will not energize, leaving the system blowing warm air or failing to start altogether. In some cases, a failed contactor will weld shut, causing the unit to run continuously even when the thermostat is satisfied.

  • Specs: 2-pole configuration | 24V AC coil voltage | Rated for single-stage cooling applications | OEM part number HN51KC024 | Factory-matched contact rating for Payne PA10JA04700GACAA
  • OEM vs Generic: This OEM contactor uses factory-specified contact materials and coil windings, ensuring proper pull-in voltage and long contact life. Generic contactors frequently use lower-grade contact alloys that pit and oxidize faster, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals to ensure correct reassembly.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Payne PA10JA04700GACAA condensing unit. Always verify the OEM part number on your existing contactor's label or the unit's wiring diagram before ordering. If you need fitment confirmation, our HVAC parts specialists are available to verify compatibility before you buy — order with confidence and get back up and running fast.

Frequently Asked Questions

Does this Contactor fit my Payne PA10JA04700GACAA?
Yes. This is the factory-specified OEM contactor for the Payne PA10JA04700GACAA. 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 PA10JA04700GACAA?
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?
