OEM Payne 2-Pole Contactor 24V Coil for Model PA10JA048000AGAA

This OEM replacement contactor (part number HN51KC024) is the factory-specified high-voltage relay for the Payne PA10JA048000AGAA 4-ton split-system air conditioner. The contactor acts as the primary switch between your thermostat's low-voltage control signal and the high-voltage power supply to the compressor and condenser fan motor. When the contactor fails, the most common symptoms include an AC system that won't turn on at all, a unit that hums but never starts, or visible pitting and burning on the contact points during inspection. Replacing a worn contactor promptly prevents compressor damage caused by voltage irregularities and arcing.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp load rating | Factory-matched contact material for reliable switching and long service life
  • OEM vs Generic: This is a genuine OEM HN51KC024 contactor built to Payne factory specifications. Generic contactors frequently use lower-grade contact alloys that pit faster under load, leading to premature failure and potential compressor damage — especially in high-cycle summer conditions.
  • Install difficulty: 3/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, multimeter, needle-nose pliers. Photograph all wiring connections before removing the old contactor. Note coil polarity and wire gauge when reconnecting.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.

Compatibility: Engineered specifically for the Payne PA10JA048000AGAA 4-ton single-stage split-system condenser. Cross-reference 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 — don't hesitate to reach out before you buy. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Payne PA10JA048000AGAA?
Yes. This is the factory-specified OEM contactor for the Payne PA10JA048000AGAA. 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 PA10JA048000AGAA?
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?
