Hi, any one out there with any suggestions why my Siemens microwave (built in) keeps cutting out after 3 seconds each time. Power is fine, all lights working, clock fine and no burning smells. Two and a half years old. Is there a part I can try replacing? Many thanks. Model HF 26066 GB.

It might be the capacitor, or H.V. Transformer. Or it could just be a disconnected door switch.
