This is the factory OEM replacement contactor for the Carrier YAC60140YAC101C condensing unit. The contactor is the high-voltage switching relay that closes when your thermostat calls for cooling, routing 240V power to both the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed 24V coil — the outdoor unit will either refuse to start entirely, run constantly without cycling off, or produce a loud buzzing/chattering sound from the electrical panel area of the condenser.
Compatibility: Designed specifically for the Carrier YAC60140YAC101C condensing unit. Always cross-reference the OEM part number HN53CD025 printed on your existing contactor's label to confirm an exact match before installing. Need help verifying fitment? Our HVAC parts specialists are available to confirm compatibility before you order — in stock and ships today.
