OEM Payne 2-Pole Contactor 24V Coil for Model PA4ZNA036000AA

This OEM contactor is the factory-specified replacement for the Payne PA4ZNA036000AA split-system air conditioner. The contactor is the 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 — due to pitted or burned contacts — your system may not respond to a cooling call at all, may run continuously without shutting off, or may cycle erratically. Replacing it with the correct OEM part restores reliable switching and protects your compressor from voltage irregularities.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched contact rating | OEM part number HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to Payne/Carrier factory tolerances. Generic contactors often use lower-grade contact materials that pit and burn faster, leading to repeat failures and potential compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify voltage is absent with a multimeter before beginning work. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Payne PA4ZNA036000AA 3-ton split-system air conditioner. Verify pole count, coil voltage, and amperage rating on your existing contactor's data label before ordering. Our parts specialists are available to confirm fitment — just reach out before you buy. Order today for same-day shipping and get your system back up and running fast.

Frequently Asked Questions

Does this Contactor fit my Payne PA4ZNA036000AA?
Yes. This is the factory-specified OEM contactor for the Payne PA4ZNA036000AA. 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 PA4ZNA036000AA?
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?
