OEM Payne 2-Pole Contactor 24V Coil for Model PA12NA03600GABAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA12NA03600GABAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When a contactor fails — due to pitted contacts, a stuck plunger, or a burned-out coil — the result is an AC unit that won't turn on, hums without starting, or runs continuously without shutting off.

  • Specs: 2-pole configuration | 24V AC coil voltage | Rated for single-stage cooling applications | Factory-matched contact material and spring tension for reliable switching
  • OEM vs Generic: OEM contactors like this HN51KC024 use contact alloys and coil windings matched to Payne factory specifications. Generic contactors often use lower-grade contact materials that pit faster under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Disconnect power at both the outdoor disconnect and the breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Payne PA12NA03600GABAA 3-ton single-stage split-system condenser. Always confirm the coil voltage and pole count on your existing contactor's label before ordering to ensure a direct match. Have questions about fitment? Our HVAC parts specialists verify compatibility before your order ships — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA03600GABAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA03600GABAA. 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 PA12NA03600GABAA?
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.
