OEM Payne 2-Pole Contactor 24V Coil for Model PA10JA04200GADAA

This is the OEM factory-specified contactor (part number HN51KC024) for the Payne PA10JA04200GADAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to deliver line-voltage power to the compressor and condenser fan motor. When it fails, the most common symptoms are the outdoor unit not turning on at all, the unit buzzing but not starting, or pitted/burned contacts causing intermittent cooling and premature compressor wear.

  • Specs: 2-pole configuration | 24V coil voltage | High-amperage switching contacts | Direct OEM replacement — factory-matched to Payne PA10JA04200GADAA specifications
  • OEM vs Generic: OEM contactors like this HN51KC024 use precision-rated contact surfaces that resist arcing and pitting. Generic contactors often use lower-grade contact materials, leading to faster degradation, voltage drop, and compressor damage over time.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3PM local time ship same business day from our climate-controlled parts warehouse.

Compatibility: Designed specifically for the Payne PA10JA04200GADAA condensing unit. Always verify the coil voltage and pole configuration on your unit's data plate before ordering. If you have any fitment questions, our HVAC parts specialists are available to confirm compatibility before you purchase — we want to make sure you get the right part the first time.

Frequently Asked Questions

Does this Contactor fit my Payne PA10JA04200GADAA?
Yes. This is the factory-specified OEM contactor for the Payne PA10JA04200GADAA. 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 PA10JA04200GADAA?
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?
