OEM Payne 2-Pole Contactor for Model PA1PNA018000ABBA

This is the factory OEM replacement contactor for the Payne PA1PNA018000ABBA split-system air conditioner, supplied under OEM part numbers HN51KB024 and HN52KC025. The contactor acts as the high-voltage switching relay in your condensing unit — when the thermostat calls for cooling, the 24V control board energizes the contactor coil, closing the high-voltage contacts that power the compressor and condenser fan motor. A failed or pitted contactor is one of the most common reasons a Payne system blows cool air at the vents but the outdoor unit never starts, or the unit hums but doesn't run.

  • Specs: 2-Pole configuration | 24V coil voltage | Rated for single-stage residential condensing unit operation | Direct OEM replacement for part numbers HN51KB024 and HN52KC025
  • OEM vs Generic: This factory OEM contactor features properly rated contact surfaces and coil windings matched to Payne's engineering specs. Generic contactors frequently use undersized contact points that pit and burn faster, causing repeat failures within a single cooling season.
  • Install Difficulty: 2/5 — Always disconnect power at the disconnect box and verify voltage is absent with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring connections before disconnecting. Swap wires one at a time to avoid miswiring.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed by 3PM local time ship same business day from our stocked warehouse.

Compatibility: Designed as the direct drop-in replacement contactor for the Payne PA1PNA018000ABBA condensing unit. Cross-references OEM part numbers HN51KB024 and HN52KC025. Always confirm coil voltage and pole configuration on your unit's data plate before ordering. Our fitment team is available to verify compatibility before you buy — no guesswork required. Order today and get your system back up and running fast with same-day shipping.

Frequently Asked Questions

Does this Contactor fit my Payne PA1PNA018000ABBA?
Yes. This is the factory-specified OEM contactor for the Payne PA1PNA018000ABBA. 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 PA1PNA018000ABBA?
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?
