Bosch Evaporator Fan Bearing Wear or Ice Contact

High-pitched squealing or whirring noise from inside the cabinet

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

Worn evaporator fan motor bearings, Fan blade rubbing on ice buildup, Fan shroud misaligned, Foreign object contacting fan

Safety: Unplug the unit before removing interior panels.

Steps:

Inspect for ice: Remove shelves and the rear interior panel. If ice surrounds the fan, fully defrost the unit and check the defrost system.
Check fan clearance: Spin the fan by hand to ensure it does not rub on the shroud or wiring. Reposition components as needed.
Replace fan motor: If the fan feels rough, wobbly, or squeals when spun, replace the evaporator fan motor assembly with a Bosch-compatible part.
