Question about Siemens HF87950GB Convection Microwave Oven

Open Question

My Siemens HF879251GB/02 Combi microwave oven was working fine until this evening when the microwave made a odd noise and switched it's self off! On further investigation I found an internal 10A fuse blown. I replaced the fuse and the unit fires up as you would expect with the conventinal oven & grill working fine. But as soon at the microwave is activated the fuse blows. Looking at the microwave there arn't too many things to go wrong. Theres a High voltage capacitor, high voltage transformer, and the Magnetron. Trouble is I'm not sure how to check if one is faulty or if there is anything else I should be looking for?

If the display is dim and another problem is denoted on the dim display, the problem may be the power supply which may be in common with both items. The power may have surged to a high level before going out which could have damaged the power supply. The only way to know is to probe the power supply with a voltmeter. If the board doesn't show the power levels, usually +5V or +/- 12 V DC, read the values on the electrolytic capacitors on the board. Usually 16 V caps are used on 12 or 5 volt supplies, 32 V caps on 24 V supplies, etc. Be very careful or leave this to a profesional
