OEM Payne 2-Pole Contactor 24V Coil for Model PA13NA048000ADAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA13NA048000ADAA split-system air conditioner. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to power the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the outdoor unit simply won't start, leaving your home without cooling even though the thermostat is calling for it. Buzzing from the disconnect box or an AC that runs continuously without cycling off are also telltale signs of contactor failure.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30-amp contact rating | Direct OEM replacement for part number HN51KC024 | Factory-matched electrical characteristics
  • OEM vs Generic: This OEM contactor is manufactured to Payne's exact coil pull-in voltage and contact resistance specifications. Generic aftermarket contactors frequently use lower-grade contact materials that pit and corrode faster, especially in humid climates, leading to repeat failures within one to two seasons.
  • Install difficulty: 3/5 — Always disconnect power at the breaker and the outdoor disconnect before beginning work. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Photograph all wiring connections before removing the old contactor. Verify power is off with a multimeter before touching any terminals.
  • Warranty: Backed by a 1-year OEM factory warranty against defects. Orders placed before our same-business-day cutoff ship directly from our stocked warehouse.

Compatibility: Engineered specifically for the Payne PA13NA048000ADAA 4-ton, 13 SEER split-system air conditioner. 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 before you buy — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA13NA048000ADAA?
Yes. This is the factory-specified OEM contactor for the Payne PA13NA048000ADAA. 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 PA13NA048000ADAA?
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?
