OEM Payne 2-Pole Contactor 24V Coil for Model PA4ANG036000BAAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA4ANG036000BAAA split-system air conditioner. The contactor is a high-voltage relay that acts as the primary switch between your thermostat's 24V control signal and the 240V power supply feeding the compressor and condenser fan. When the contactor fails — due to burned or pitted contact points, a stuck plunger, or a failed coil — the system will either refuse to start entirely, short-cycle unpredictably, or run continuously without responding to thermostat commands.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp contact rating | Direct OEM replacement for part number HN51KC024 | Factory-matched contact material and coil resistance
  • OEM vs Generic: This OEM contactor uses factory-spec contact alloys and coil windings, ensuring the correct pull-in voltage and contact resistance. Generic contactors often use inferior contact materials that pit and arc faster, shortening service life — especially in high-cycle cooling climates.
  • Install difficulty: 3/5 — Always shut off power at both the disconnect box and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter to verify de-energization. Photograph all wiring before removing the old contactor. Line-voltage terminals are present — exercise caution.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders ship same business day from our stocked warehouse.

Compatibility: Designed specifically for the Payne PA4ANG036000BAAA 3-ton split-system condenser. Always confirm the coil voltage and pole configuration on your unit's wiring diagram or data plate before ordering. Our HVAC parts specialists are available to verify fitment — reach out before you order if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Payne PA4ANG036000BAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA4ANG036000BAAA. 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 PA4ANG036000BAAA?
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?
