OEM Payne 2-Pole Contactor 24V Coil for Model PA3ANA048000BAAA

This is the OEM factory-specified contactor (part number HN51KC024) for the Payne PA3ANA048000BAAA 4-ton split-system air conditioner. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — it closes the circuit to deliver 240V power to the compressor and condenser fan motor every time a cooling call is made. A failed contactor is one of the most common reasons an AC condenser won't start: symptoms include the unit not energizing at all, chattering or buzzing at the contactor, pitted or burned contact points, or a coil that no longer pulls in under load.

  • Specs: 2-pole configuration | 24V AC coil voltage | 40A contact rating | Direct OEM replacement for part number HN51KC024 | Factory-matched contact material and coil resistance
  • OEM vs Generic: OEM contactors use silver-alloy contact points engineered to factory arc-resistance specifications. Generic contactors often use lower-grade contact materials that pit faster, increasing resistance and shortening compressor life under repeated start loads.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify voltage is absent with a multimeter before starting. 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. In-stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Payne PA3ANA048000BAAA 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 fitment team is available to verify compatibility prior to purchase — same-day shipping on all in-stock orders placed before 3 PM local time.

Frequently Asked Questions

Does this Contactor fit my Payne PA3ANA048000BAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA3ANA048000BAAA. 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 PA3ANA048000BAAA?
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?
