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

Loose blower wheel, Debris in blower housing, Worn exhaust fan motor bearings, Improper installation to cabinet or wall
