OEM Payne Contactor 2-Pole 24V Coil for Model PA1PNA036000ABBA

This is the factory OEM replacement contactor (part number HN51KB024) for the Payne PA1PNA036000ABBA split-system air conditioner. The contactor is the high-voltage relay that bridges the gap between your thermostat's 24V control signal and the 240V power supply to your compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — your air conditioner will either refuse to start entirely, run continuously without shutting off, or fail to respond to thermostat calls for cooling.

  • Specs: 2-pole design | 24V AC coil voltage | 30–40A contact rating | Direct OEM replacement for part number HN51KB024 | Factory-matched contact material for long service life
  • OEM vs Generic: OEM contactors like this HN51KB024 use factory-grade silver-alloy contact tips rated for thousands of switching cycles. Generic contactors often use inferior contact materials that pit and burn prematurely, leading to repeat failures within a single cooling season.
  • Install difficulty: 3/5 — Requires disconnecting 240V power at the disconnect box before beginning work. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and insulated gloves. Photograph all wiring connections before removal. If unfamiliar with high-voltage wiring, consult a licensed HVAC technician.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before our same-day shipping cutoff ship from our warehouse the same business day.

Compatibility: This contactor is the direct OEM replacement for the Payne PA1PNA036000ABBA (3-ton) split-system condenser. Confirm your existing contactor's pole count, coil voltage, and amperage rating against your unit's wiring diagram before ordering. Our fitment team is available to verify compatibility prior to purchase — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Payne PA1PNA036000ABBA?
Yes. This is the factory-specified OEM contactor for the Payne PA1PNA036000ABBA. 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 PA1PNA036000ABBA?
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?
