Freezer only cools at the top or bottom; uneven temperature distribution inside.

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

Evaporator fan not running, Ice blocking air ducts, Shelves or food blocking air vents, Fan motor running slowly due to wear

Safety: Unplug the freezer before removing interior panels.

Steps:

Check vents: Ensure that air vents at the back and sides are not blocked by food items.
Listen for fan: With the door switch held closed, listen for the evaporator fan running. If silent, suspect fan failure.
Inspect for ice: Remove drawers and the rear panel to check for ice blocking the fan or ducts. Defrost as needed.
Replace fan: If the fan motor is not running or is noisy/slow, replace it with a Bosch-compatible evaporator fan motor.
