OEM Carrier Contactor 24V Coil for Model PY3GNAA30060NA — HN51KC024

This is the factory-specified OEM replacement contactor for the Carrier PY3GNAA30060NA packaged unit. The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the stat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an AC system will hum but fail to start, trip the breaker repeatedly, or simply not respond to a cooling call at all.

  • Specs: OEM Part No. HN51KC024 | 24V AC coil voltage | High-amperage switching contacts | Direct factory replacement — no modifications required
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact coil pull-in voltage and contact amp rating. Aftermarket contactors frequently use lower-grade contact material that pits and welds faster under the high inrush current of a compressor start, leading to premature failure and potential compressor damage.
  • Install Difficulty: 2/5 — Always disconnect power at both the disconnect box and the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring before removing the old contactor.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY3GNAA30060NA packaged unit. Verify coil voltage and pole configuration on your unit's data plate before ordering. Our technical team is available to confirm fitment — reach out before you buy if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier PY3GNAA30060NA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier PY3GNAA30060NA — HN51KC024. 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 PY3GNAA30060NA — HN51KC024?
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.
