OEM Carrier 2-Pole Contactor 24V Coil for Model PY4GNAB30060NA

This is the factory-specified OEM contactor (part number HN51KC024) for the Carrier PY4GNAB30060NA packaged unit. The contactor is a high-voltage relay that acts as the main power switch for the compressor and condenser fan motor — closing when the thermostat calls for cooling and opening when the cycle ends. Common failure symptoms include the unit not turning on at all, audible chattering or buzzing from the contactor coil, pitted or burned contacts causing intermittent operation, or the system running continuously without shutting off.

  • Specs: 2-Pole configuration | 24V AC coil voltage | High-amperage load contacts | Direct OEM replacement — factory-matched to Carrier specifications
  • OEM vs Generic: This OEM contactor uses factory-grade contact material and coil windings, ensuring precise pull-in voltage and long contact life. Generic alternatives often use lower-grade contact alloys that pit faster under high-amperage switching, leading to premature failure.
  • Install difficulty: 3/5 — Always shut off power at the disconnect and verify with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal and transfer one wire at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty included. Orders placed by 3PM local time ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY4GNAB30060NA packaged unit. Always cross-reference the OEM part number HN51KC024 printed on your existing contactor's label before ordering to confirm a direct fit. Our technical team is available to verify compatibility prior to purchase — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier PY4GNAB30060NA?
Yes. This is the factory-specified OEM contactor for the Carrier PY4GNAB30060NA. 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 PY4GNAB30060NA?
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.
