Bosch Evaporator Fan Bearing Wear

Freezer produces a high-pitched whine or squeal 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 fan motor bearings, Ice contacting fan blades, Fan blade misaligned on shaft

Safety: Unplug the freezer before accessing the fan area.

Steps:

Defrost ice: If noise changes when the door is opened or after defrosting, ice may be contacting the fan. Manually defrost the evaporator area.
Access fan: Remove drawers and the rear interior panel to reach the evaporator fan.
Inspect fan: Check for wobbling blades or play in the motor shaft. If the motor is noisy when spun by hand, it is worn.
Replace fan motor: Install a Bosch-compatible evaporator fan motor and ensure the blade is correctly seated.
