OEM Payne Contactor 2-Pole 24V Coil for Model PA12NA030000ACAA

This is the OEM replacement contactor (part number HN51KC024) for the Payne PA12NA030000ACAA 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 a contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — your outdoor unit will either fail to start entirely, run continuously without shutting off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V AC coil voltage | High-amperage load contacts | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This is the factory-specified OEM contactor engineered to exact tolerances for the PA12NA030000ACAA. Generic contactors frequently use lower-grade contact materials that pit faster under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. Discharge any capacitors in the vicinity before working nearby.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as the direct factory replacement for the Payne PA12NA030000ACAA split-system condenser. Cross-reference OEM part number HN51KC024 against your unit's data plate and wiring diagram to confirm fitment before ordering. Not sure it's the right part? Our HVAC parts specialists verify compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA12NA030000ACAA?
Yes. This is the factory-specified OEM contactor for the Payne PA12NA030000ACAA. 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 PA12NA030000ACAA?
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.
