OEM Payne 2-Pole Contactor 24V Coil for Model PA3GNAA24000AA

This is the factory-specified OEM replacement contactor (part number HN51KC024) for the Payne PA3GNAA24000AA split-system air conditioner. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to power the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an air conditioner that won't turn on at all, intermittent cooling failures, or a unit that runs continuously without cycling off due to welded contacts.

  • Specs: 2-pole configuration | 24V AC coil voltage | High-amperage switching contacts | Direct OEM replacement for part number HN51KC024 | Factory-matched contact ratings for reliable high-voltage switching
  • OEM vs Generic: This OEM contactor is manufactured to Payne's exact factory specifications, ensuring proper coil pull-in voltage and contact durability. Generic contactors often use lower-grade contact materials that pit and weld prematurely, leading to repeat failures within a single cooling season.
  • Install difficulty: 3/5 — This repair involves live 240V wiring. Always disconnect power at the breaker and verify voltage is off with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or camera for documenting existing wiring connections before removal.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Payne PA3GNAA24000AA split-system air conditioner. Always verify coil voltage and pole configuration on your unit's data plate prior to ordering to ensure correct fitment. Our HVAC parts specialists are available to confirm compatibility before you purchase — no guesswork required. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Payne PA3GNAA24000AA?
Yes. This is the factory-specified OEM contactor for the Payne PA3GNAA24000AA. 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 PA3GNAA24000AA?
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?
