Liebherr Overheating Motor or Thermal Overload Trip

Dryer stops mid-cycle and shuts off completely, then can be restarted after a cool-down period.

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

Blocked airflow causing high internal temperature, Worn motor bearings causing overheating, Failing motor thermal protector, Excessive load size

Safety first: Unplug the dryer and allow it to cool before inspection.

Reduce load size: Avoid overloading the drum. Large, heavy loads can strain the motor.
Clean airflow path: Ensure lint filter, condenser, and exhaust duct are clean and unobstructed.
Check drum movement: Rotate the drum by hand. If stiff, inspect rollers, idler, and rear bearing for drag and replace worn parts.
Motor inspection: Access the motor and check for excessive heat discoloration or noise. A motor that repeatedly trips its thermal protector should be replaced.
