Fan motor fault

An interior circulation fan isn't running as commanded. Cold air stops moving evenly, so some areas run cold while others warm up — the classic symptom is temperature stratification between shelves. Ice jamming the fan or a failed fan motor are the documented causes.

    Power-reset

    Switch off for 60 seconds and back on; listen for the fan resuming.

    Manual defrost if iced

    If you hear the fan straining or chirping, a full defrost (off, doors open, 24h) frees an ice-jammed blade.

  3. 3

    Book fan replacement

    If the fan stays silent after a thaw and reset, the motor has failed.

Switch the appliance off for 60 seconds and back on. A 24-hour manual defrost is the one effective self-help step before service.
