OEM Carrier Single-Pole Contactor 1-Pole 24V 30A for Model PY4GNAB30060AA

This is the factory-authorized OEM replacement contactor for the Carrier PY4GNAB30060AA packaged unit. The contactor is the high-voltage relay that closes whenever the thermostat calls for cooling or heating, sending line-voltage power to the compressor and condenser fan motor. When the contactor fails — due to pitted or welded contacts, a burned coil, or a chattering relay — the system will either refuse to turn on, run continuously without stopping, or hum loudly without engaging. Replacing it promptly prevents compressor damage and restores full system operation.

  • Specs: 1-Pole | 24 VAC coil voltage | 30 A FLA (Full Load Amps) | 150 A LRA (Locked Rotor Amps) | 50/60 Hz | OEM Part Number HN51KC024
  • OEM vs Generic: Factory-authorized OEM contactors are built to Carrier's exact contact gap, coil pull-in voltage, and thermal rating tolerances. Generic contactors may use lower-grade contact alloys that pit faster under high-cycle residential use, shortening compressor life and risking nuisance trips.
  • Install Difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in with a multimeter after installation before restoring power.
  • Warranty & Shipping: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Frequently Asked Questions

Does this Contactor fit my Carrier PY4GNAB30060AA?
Yes. This is the factory-specified OEM contactor for the Carrier PY4GNAB30060AA. 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 PY4GNAB30060AA?
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?
