OEM Payne 2-Pole Contactor 24V Coil for Model PA4RNG030000BAAA

This OEM contactor (part number HN51KC024) is the factory-specified replacement for the Payne PA4RNG030000BAAA 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, the most common symptoms include the outdoor unit not turning on at all, visible pitting or burning on the contact points, or the system running continuously without shutting off due to contacts welded shut.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp rated | Factory-matched OEM replacement for part number HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to Payne's exact contact material and coil specifications, ensuring proper voltage drop and contact life. Generic contactors may use inferior contact alloys prone to early pitting, reducing service life significantly in high-cycle environments.
  • Install Difficulty: 3/5 — Always disconnect power at the disconnect box and verify voltage is zero with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Designed specifically for the Payne PA4RNG030000BAAA air conditioning unit. Always verify the OEM part number HN51KC024 and coil voltage against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you purchase — same-day shipping available on all in-stock parts.

Frequently Asked Questions

Does this Contactor fit my Payne PA4RNG030000BAAA?
Yes. This is the factory-specified OEM contactor for the Payne PA4RNG030000BAAA. 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 PA4RNG030000BAAA?
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.
