Loud buzzing or grinding noise from outdoor unit

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failing outdoor fan motor bearings, Loose fan blade, Debris contacting fan, Compressor internal mechanical wear

Safety first: Turn off power at the outdoor disconnect.

Inspect fan assembly: Remove the top grille if needed and check that the fan blade is tight on the motor shaft and not contacting the shroud.
Remove debris: Clear any sticks, leaves, or plastic from the fan area.
Spin test: Spin the fan by hand. Roughness or noise indicates bad bearings; replace the fan motor.
Compressor noise: If the noise clearly comes from the compressor body, it may be failing. A technician should evaluate and replace the compressor if necessary.
