OEM Payne 2-Pole Contactor HN51KC024 for Model PA10JA042000AGAA

This OEM replacement contactor is the factory-specified part for the Payne PA10JA042000AGAA split-system air conditioner. The contactor acts as a high-voltage relay, switching power to the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails — due to pitted contacts, a stuck plunger, or a burned-out coil — the outdoor unit will fail to energize entirely, leaving your system blowing warm air or not responding at all.

  • Specs: 2-pole configuration | 24V coil voltage | High-amperage contacts rated for compressor load | OEM part number HN51KC024 | Direct factory replacement
  • OEM vs Generic: This OEM contactor uses factory-spec contact materials and coil windings, ensuring precise pull-in voltage and long contact life. Generic contactors may use inferior contact alloys prone to early pitting, increasing the risk of premature compressor failure.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all high-voltage wiring connections before removal.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed as a direct OEM replacement for the Payne PA10JA042000AGAA split-system condenser. Cross-references OEM part number HN51KC024. Confirm coil voltage and pole count on your unit's data plate before ordering. Our team is available to verify fitment — don't hesitate to reach out before you buy.

Frequently Asked Questions

Does this Contactor fit my Payne PA10JA042000AGAA?
Yes. This is the factory-specified OEM contactor for the Payne PA10JA042000AGAA. 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 PA10JA042000AGAA?
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.
