Smeg Oven: grinding noise

Professional Repair Guide

What is this symptom?

Experiencing a grinding noise from your Smeg oven? This could indicate issues with the convection fan motor or internal components. Such sounds are often abnormal and may be caused by worn bearings, obstructed fan blades, or loose hardware, resulting in an unpleasant cooking experience. Identifying the source early can help prevent further damage.
