OEM Payne 2-Pole Contactor 24V Coil for Model PA1ZNA024000ACAA

This is the factory OEM replacement contactor (part number HN51KB024) for the Payne PA1ZNA024000ACAA split-system air conditioner. The contactor is a high-voltage relay that switches power to the compressor and condenser fan motor each time your thermostat calls for cooling. When it fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the outdoor unit simply will not energize, leaving you with warm air and a running air handler with no cooling effect. In some cases a failed contactor will weld shut, causing the outdoor unit to run continuously regardless of thermostat demand.

  • Specs: 2-pole configuration | 24V AC coil voltage | Heavy-duty silver-alloy contacts | Rated for residential split-system compressor loads | Direct OEM replacement for part number HN51KB024
  • OEM vs Generic: This factory OEM contactor is wound and rated to exact Payne specifications. Generic contactors frequently use lower-grade contact materials that pit faster under compressor inrush current, leading to repeat failures within a single season.
  • Install difficulty: 3/5 — Always disconnect and lock out power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all high-voltage wire positions before removal. The 24V coil wires from the control board must be reconnected to the correct terminals.
  • Warranty: 1-year OEM factory warranty against defects. In-stock units ship the same business day from our warehouse.

Compatibility: Designed as a direct drop-in replacement for the Payne PA1ZNA024000ACAA 2-ton split-system condenser. Confirm your existing contactor matches a 2-pole, 24V coil configuration by reading the data plate on the unit or the label on the existing contactor before ordering. Our fitment specialists are available to verify compatibility prior to purchase — same-day shipping available on all in-stock OEM parts.

Frequently Asked Questions

Does this Contactor fit my Payne PA1ZNA024000ACAA?
Yes. This is the factory-specified OEM contactor for the Payne PA1ZNA024000ACAA. 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 PA1ZNA024000ACAA?
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?
