Brandt Unstable Temperature Control

Freezer temperature fluctuates widely; sometimes too warm, sometimes too cold

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

Faulty temperature sensor, Poor air circulation due to blocked vents, Control board logic fault, Ambient temperature outside design range

Safety first: Unplug the freezer before accessing sensors or panels.

Steps:

Check loading: Avoid blocking air vents with packages. Allow space for air to circulate.
Verify ambient conditions: Ensure the freezer is installed in a room within the temperature range specified by Brandt.
Test temperature sensor: Measure NTC resistance and replace if unstable or out of spec.
If sensor is good: Replace the main control board to correct erratic control.
