OEM Carrier Contactor 24V Coil 2-Pole for Model PY3GNAA36060AA

This is the factory OEM replacement contactor for the Carrier PY3GNAA36060AA packaged unit. The contactor is a high-voltage relay that switches line-voltage power (240V) to the compressor and condenser fan motor using a low-voltage (24V) signal from the thermostat. When the contactor fails, the system will not respond to a cooling call — you may hear a humming or clicking at the unit with no compressor startup, or experience intermittent cooling loss due to pitted or welded contacts.

  • Specs: OEM Part Number HN51KC024 | 2-pole configuration | 24V coil voltage | Rated for 240V line-voltage switching | Factory-spec contact rating for compressor load
  • OEM vs Generic: This OEM contactor is built to Carrier's exact coil pull-in voltage and contact load specifications. Generic aftermarket contactors frequently feature substandard contact plating, leading to faster pitting, arc damage, and premature compressor wear.
  • Install difficulty: 3/5 — Always shut off power at the disconnect box and confirm voltage is absent with a multimeter before touching any wiring. Photograph all wiring connections before removal. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester.
  • Warranty: 1-year OEM factory warranty included. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY3GNAA36060AA packaged unit. Always verify OEM part number HN51KC024 against your unit's wiring diagram or data plate before ordering. Not sure about fitment? Our HVAC parts specialists verify compatibility before you buy — contact us today and ship with confidence.

Frequently Asked Questions

Does this Contactor fit my Carrier PY3GNAA36060AA?
Yes. This is the factory-specified OEM contactor for the Carrier PY3GNAA36060AA. 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 PY3GNAA36060AA?
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?
