Kenmore Microwave Problem

Question

HI

 

Have a Kenmore model 665.61629100 microwave. We had a power surge and the micro wave is not working properly. The clock works and the light comes on inside, but, it will not operate to heat up food. There is a "d" showing to the right of the time on the LED. Is this a code for some error?

 

Thanks for your help.
