OEM Payne 2-Pole Contactor 24V Coil for Model PA3ANA018000BAAA

This OEM contactor (part number HN51KC024) is the factory-specified high-voltage relay for the Payne PA3ANA018000BAAA split-system air conditioner. The contactor acts as the primary switching device that sends 240V power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your outdoor unit will not energize even though the indoor air handler continues to run, leaving you with warm air and a spinning blower but no cooling.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30-amp contact rating | Replaces OEM part number HN51KC024 | Factory-matched coil pull-in voltage for reliable engagement
  • OEM vs Generic: This factory OEM contactor features silver-alloy contacts rated to exact factory specifications. Generic contactors frequently use lower-grade contact materials that pit, weld, or fail prematurely under high-cycle summer loads, shortening compressor life significantly.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and wait 5 minutes before touching any wiring. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Contactor installs with two mounting screws and screw-terminal connections.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Payne PA3ANA018000BAAA 1.5-ton split-system condenser. Confirm your existing contactor's pole count, coil voltage, and amperage rating on the data plate or existing contactor label before ordering. Our HVAC parts specialists are available to verify fitment — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Contactor fit my Payne PA3ANA018000BAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA3ANA018000BAAA. 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 PA3ANA018000BAAA?
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.
