OEM Payne Contactor HN51KC024 for Model PA12NA04200GAGAA

This OEM Payne contactor (HN51KC024, 1-pole, 30A, 24V coil) is the heavy-duty relay that switches power to your air conditioner's compressor and condenser fan motor on each cooling call from the thermostat. Designed as a direct factory replacement for the Payne PA12NA04200GAGAA condensing unit, it provides reliable high-amperage switching at the exact coil voltage your system needs. Over thousands of cycles, contactor contacts pit, corrode, or weld shut—leading to a unit that won't start, buzzes loudly, or runs nonstop. Replacing it with a genuine OEM part restores clean, dependable operation. This is a beginner-friendly repair for most homeowners: cut power at the disconnect, take a photo of the wiring, move each lead to the matching terminal on the new contactor, and fasten it down—about 15 to 20 minutes. Always confirm power is off with a meter before starting. OEM specs ensure correct amperage and UL-listed safety. In stock and ready to ship—orders placed before 3PM CST ship the same business day.

Frequently Asked Questions

Does this Contactor fit my Payne Model PA12NA04200GAGAA?
Yes. This is the factory-specified OEM contactor for the Payne Model PA12NA04200GAGAA. 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 Model PA12NA04200GAGAA?
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.
