Oven goes off sometimes when baking/broiling. When this happens clock and temp indicator go off. Oven comes back on usually after a few minutes or after we tap on cooktop bezel.
When clock comes back on, it has lost the minutes it was out, does not flash 12:00 as if power was completely lost. Oven temp must be reset.
If it goes out for 5 mins, for example, at 5:05, it comes back showing that time although other clocks will have advanced to 5:10.
What could cause this; what part should be replaced to fix this?
HELP!
