OEM Payne 2-Pole Contactor 24V Coil for Model PA17NA02400GBAAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA17NA02400GBAAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to supply 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 — the most common symptom is an air conditioner that won't turn on at all, even though the thermostat is calling for cooling. You may also hear a loud chattering or buzzing from the outdoor unit.

  • Specs: 2-pole configuration | 24V coil voltage | Rated for single-stage R-410A condensers | OEM part number HN51KC024 | Factory-matched contact rating for the PA17NA02400GBAAA platform
  • OEM vs Generic: OEM contactors use factory-spec contact materials and coil windings, ensuring proper pull-in voltage and long service life. Generic contactors may use lower-grade contact alloys that pit faster under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and breaker before beginning. 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 against defects in materials and workmanship. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Payne PA17NA02400GBAAA split-system condenser. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our parts specialists are available to confirm fitment — order with confidence and get your system back up and running today.

Frequently Asked Questions

Does this Contactor fit my Payne PA17NA02400GBAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA17NA02400GBAAA. 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 PA17NA02400GBAAA?
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?
