OEM Carrier Contactor 2-Pole 24V Coil for Model PY3GNA036060AB

The Carrier HN51KB024 is the factory-specified OEM replacement contactor for the PY3GNA036060AB split-system condenser. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send line-voltage power to the compressor and condenser fan motor. When it fails, your air conditioner may not turn on at all, may run continuously without shutting off, or you may hear a chattering or buzzing noise from the outdoor unit — all classic signs of a worn or pitted contactor.

  • Specs: 2-Pole contactor | 24V AC coil voltage | Factory-matched amp rating | Direct OEM replacement for Carrier part number HN51KB024
  • OEM vs Generic: This OEM contactor uses factory-grade silver-alloy contact tips that resist pitting and arcing far longer than generic alternatives. Off-brand contactors often use cheaper alloys that degrade rapidly under summer load, leading to repeat failures within a single season.
  • Install difficulty: 2/5 — Always shut off power at the disconnect box and verify zero voltage with a multimeter before touching any terminals. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Swap wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct drop-in replacement for Carrier model PY3GNA036060AB. Always verify the coil voltage and pole configuration on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you order — contact us anytime.

Frequently Asked Questions

Does this Contactor fit my Carrier PY3GNA036060AB?
Yes. This is the factory-specified OEM contactor for the Carrier PY3GNA036060AB. 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 PY3GNA036060AB?
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?
