OEM Carrier 2-Pole Contactor 24V Coil for Model PY3GNAA36090NA

This is the factory OEM replacement contactor for the Carrier PY3GNAA36090NA packaged unit. The contactor is the high-voltage relay that receives the 24V signal from your thermostat and closes the circuit to energize the compressor and condenser fan motor. When the contactor fails — whether due to pitted contacts, a burned coil, or a stuck plunger — the result is typically an air conditioner that refuses to start, buzzes loudly without cooling, or trips the breaker repeatedly. Replacing it with the correct OEM part (HN51KC024) ensures precise coil voltage response and contact rating, protecting your compressor investment.

  • Specs: 2-Pole configuration | 24V AC control coil | High-amperage contact rating | OEM Part Number HN51KC024 | Factory-matched for Carrier PY3GNAA36090NA
  • OEM vs Generic: OEM contactors use factory-spec contact alloy and coil windings calibrated to your unit's exact pull-in and drop-out voltage range. Generic contactors frequently use lower-grade contact materials that pit faster, increasing compressor wear and shortening equipment life.
  • Install difficulty: 3/5 — Always shut off power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter for coil/contact verification. Photo all wiring before removing the old contactor. Consult a licensed HVAC technician if unsure.
  • Warranty: 1-year OEM factory warranty. Orders placed by cutoff ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY3GNAA36090NA packaged unit. Verify OEM part number HN51KC024 on your unit's wiring diagram or data plate before ordering. Our team is available to confirm fitment — just reach out before you buy. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier PY3GNAA36090NA?
Yes. This is the factory-specified OEM contactor for the Carrier PY3GNAA36090NA. 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 Carrier PY3GNAA36090NA?
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 Carrier 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 Carrier 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?
