I have a Sharp KB-3300JS range / microwave. A couple of days ago I tried to turn off the oven after cooking a sandwich. The oven would not turn off and stayed on broil. None of the keys on the keypad would work. Microwave is on the same panel and it would not work either. To get it to turn off, I turned off the breaker at the breaker box. The next morning I turned the breaker on again and now there is nothing appearing on the panel to turn it on, off, microwavce, timer, etc. It is as if there is no pwer getting to the panel at all. The burners on top, the range, works fine. What can I do to fix this problem without calling a repairman? Thanks, Frank
