Blomberg Thermostat / Temperature Control Fault

Refrigerator runs constantly and is too cold, food freezing in the fresh food compartment.

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 reading low, Stuck relay on control board, Incorrect temperature setting, Air damper stuck open

Settings and loading:

Verify the temperature setting is not at the coldest position; set to a mid-range and monitor.
Avoid placing highly perishable items directly in front of cold air vents.

Sensor and control:

If the display shows a much lower temperature than an actual thermometer, the sensor may be faulty.
Unplug the unit for 5 minutes to reset the control. If the compressor still runs nearly nonstop and temperatures remain too low, the control board or sensor likely needs replacement.
