OEM Payne 2-Pole Contactor HN51KC024 for Model PA13NR042000ACAA

This OEM contactor (part number HN51KC024) is the factory-specified replacement for the Payne PA13NR042000ACAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit 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 — the outdoor unit will not energize, leaving you with no cooling even though the indoor air handler continues to run.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp contact rating | Direct OEM replacement matching factory electrical specifications
  • OEM vs Generic: OEM contactors like the HN51KC024 use silver-alloy contact tips rated for thousands of switching cycles. Generic alternatives frequently use lower-grade contacts that pit quickly under load, causing premature compressor damage and repeat failures.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and confirm voltage is absent with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Payne PA13NR042000ACAA 3.5-ton single-stage R-410A 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 HVAC parts specialists are available to confirm fitment — reach out before you buy for total peace of mind.

Frequently Asked Questions

Does this Contactor fit my Payne PA13NR042000ACAA?
Yes. This is the factory-specified OEM contactor for the Payne PA13NR042000ACAA. 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 PA13NR042000ACAA?
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?
