Dead microwave! I have an older Kenmore microwave/hood combo model number 665.68610891 that has stopped working.  One minute all was well and the next - nothing.  At first I thought I had blown a fuse, but this was not the case.  Can it be repaired?  Is it worth it to pay Sears $75 just to diagnose the problem (it's almost 10 years old), or should I just spring for a new one around $200?  Thanks, Kevin B.

Hi Kevin

If your microwave oven doesn't seem to work at all, check these:
Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.

If still you are unable to diagnose the issue then it is recommended to call a local repair center for this to get fixed as Microwave usually have high voltage even when it is turned off.

Please do rate the solution as FixYa and revert for further assistance.

Thanks
