Treat the loss of suitable storage seriously and arrange assessment. Silence alone can be normal at times, but the accompanying warming changes the significance.
What the observation tells you
The cause may involve supply, controls or another fault; a light remaining on does not identify which. Do not open covers, touch rear machinery or repeatedly reconnect power to encourage a start. Any burning smell or electrical damage requires safe stopping.
A useful next step
Protect both food groups, note the display and interruption history and provide the model. Confirmed compressor or sealed-circuit work is outside this service's scope.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
