OEM Carrier 1-Pole Contactor 30 Amp 24V for Model PY3GNAA30060AA (Part# HN51KC024)

This is the genuine OEM single-pole contactor factory-specified for the Carrier PY3GNAA30060AA packaged unit. The contactor is a high-voltage switching relay controlled by the 24V thermostat signal — it closes to send line voltage to the compressor and/or fan motor every time there is a call for cooling. When the contactor fails, contacts can pit, burn, or weld shut, leaving you with an AC system that won't start, short-cycles, or runs continuously without responding to the thermostat. Replacing a failed contactor promptly protects downstream components like the compressor from damage due to improper voltage delivery.

  • Specs: 1-Pole configuration | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM Part# HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact factory tolerances. Generic contactors often use lower-grade contact materials prone to pitting and arcing, which can accelerate compressor wear and lead to premature re-failure.
  • Install Difficulty: 2/5 — Shut off power at the disconnect box and wait for capacitors to discharge before touching any terminals. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph existing wiring before removing the old contactor. Verify 24V coil pull-in after installation with a thermostat call.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back online fast.

Compatibility: Designed for the Carrier PY3GNAA30060AA packaged gas/electric unit. Verify your unit's data plate lists part number HN51KC024 or cross-references P282-0311 before ordering. Have questions about fitment? Our HVAC parts specialists confirm compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier PY3GNAA30060AA?
Yes. This is the factory-specified OEM contactor for the Carrier PY3GNAA30060AA. 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 PY3GNAA30060AA?
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?
