OEM Payne Contactor HN51KC024 for Model PA10JA042000ACAA

Keep your Payne air conditioner switching cleanly with this OEM contactor, part number HN51KC024, engineered for the PA10JA042000ACAA condensing unit. The contactor is the electrical switch that energizes your compressor and condenser fan motor each time the thermostat calls for cooling. Over time the contact points pit, burn, and stick, causing hard starts, constant buzzing, or a unit that won't shut off. This genuine factory replacement provides the correct coil voltage rating and contact configuration your Payne system was built for, ensuring reliable, chatter-free operation. Generic contactors can mismatch amperage or coil specs and fail prematurely; this OEM part meets Payne's exact standards. Installation is straightforward for a qualified technician — disconnect power, photograph the wiring, transfer each lead to the matching terminal, and remount. Most pros complete the swap in 20 to 30 minutes. Always confirm power is off before servicing. Order before 3PM CST and your contactor ships the same day so your Payne system is cooling again fast. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Payne Model PA10JA042000ACAA?
Yes. This is the factory-specified OEM contactor for the Payne Model PA10JA042000ACAA. 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 PA10JA042000ACAA?
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.
