OEM Carrier Single-Pole Contactor 30 Amp 24V for Model PY3GNAA42060NA

This is the factory OEM replacement contactor for the Carrier PY3GNAA42060NA packaged unit. The contactor is the high-voltage relay that receives a 24V signal from the thermostat control board and closes to energize the compressor and/or fan motor at line voltage. When the contactor fails — through burned contacts, a welded-shut coil, or a failed coil — the system will either refuse to turn on entirely, run continuously without shutting off, or trip the breaker. Replacing it is one of the most common and cost-effective AC repairs available.

  • Specs: 1-Pole (single-pole) | 30 Amp FLA / 150 Amp LRA | 24 VAC coil voltage | 50/60 Hz | OEM part number HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact equipment specifications. Generic contactors often have looser contact tolerances and lower-grade coil windings, increasing the risk of premature failure and compressor damage.
  • Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in after reinstallation.
  • Warranty: 1-year OEM factory warranty included. Orders ship same business day from our warehouse stock.

Compatibility: Designed for Carrier model PY3GNAA42060NA packaged units. Verify your unit's wiring diagram and parts list confirms HN51KC024 before ordering. Not sure? Our fitment team confirms compatibility before you buy — contact us today and get your unit running again fast.

How do I replace the contactor on my Carrier OEM Carrier Single-Pole Contactor 1P 30A 24V — PY3GNAA42060NA?

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.
