OEM Payne 2-Pole Contactor 24V Coil for Model PA13NA042000ACAA

This OEM contactor (part number HN51KC024) is the factory-specified replacement for the Payne PA13NA042000ACAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from your thermostat and closes to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your AC unit will hum without starting, fail to cool entirely, or run continuously without shutting off.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp rated | Direct OEM replacement for part number HN51KC024 | Factory-matched contact material for long service life
  • OEM vs Generic: This factory OEM contactor uses precision contact alloys rated to exact pull-in voltage specs. Generic contactors frequently use lower-grade contact materials that pit and weld faster, leading to repeat failures — especially in high-cycle summer operation.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Discharge any capacitors nearby before working in the control box.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Payne PA13NA042000ACAA 3.5-ton single-stage R-410A split-system condenser. Always verify the OEM part number on your existing contactor's label and confirm coil voltage and pole count on your unit's wiring diagram before ordering. Our parts specialists are available to confirm fitment — reach out before you buy if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Payne PA13NA042000ACAA?
Yes. This is the factory-specified OEM contactor for the Payne PA13NA042000ACAA. 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 PA13NA042000ACAA?
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.
How fast does National HVAC Parts ship?
