OEM Payne 2-Pole Contactor 24V Coil for Model PA3ANA024000BBAA

This is the OEM replacement contactor (part number HN51KC024) factory-specified for the Payne PA3ANA024000BBAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and switches line-voltage power to the compressor and condenser fan motor. When it fails, your system may not respond to a cooling call at all, may short-cycle, or you may hear a clicking sound with no compressor engagement. Burned or pitted contacts are the most common failure mode and a leading cause of no-cooling calls in the field.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Payne PA3ANA024000BBAA | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to exact Payne/Carrier factory specifications, ensuring proper coil pull-in voltage, contact rating, and service life. Generic contactors may use lower-grade contact materials that pit faster and reduce system reliability.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Payne PA3ANA024000BBAA split-system condenser. Always verify the coil voltage and pole configuration on your unit's data plate before ordering. Not sure about fitment?

Frequently Asked Questions

Does this Contactor fit my Payne PA3ANA024000BBAA?
Yes. This is the factory-specified OEM contactor for the Payne PA3ANA024000BBAA. 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 PA3ANA024000BBAA?
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.
