OEM Payne 2-Pole Contactor 24V Coil for Model PA4ANG048000BAAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA4ANG048000BAAA 4-ton split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to deliver 240V power to the compressor and condenser fan motor. When the contactor fails — due to worn or pitted contacts, a burned coil, or contacts welded shut — you'll see symptoms like the AC not turning on at all, the outdoor unit running constantly without shutting off, or an audible buzzing from the contactor itself with no compressor startup.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for 4-ton (048) condensers | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This factory OEM contactor is manufactured to exact Payne/Carrier specifications, ensuring proper coil pull-in voltage and contact rating. Generic contactors may use undersized contacts that pit and fail prematurely under high-load summer cycling conditions.
  • Install difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Photograph all wire connections before removal.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse — get your system running fast.

Compatibility: Designed specifically for the Payne PA4ANG048000BAAA 4-ton split-system condenser. Always verify the OEM part number HN51KC024 against your unit's data plate or existing contactor label before ordering. Our fitment specialists are available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA4ANG048000BAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA4ANG048000BAAA. 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 PA4ANG048000BAAA?
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?
