I have a Kenmore microwave 1 yr old. installed in our New Home by Sears. Sunday when I shut the door the lights on the panel went out and the light inside the microwave went out. When I open the door the light flickers like it is going out, when u push up on the screen it stops and shut it again the lights all across the outside panel light up, it beeps and then goes off again.. I was looking for a repair manual for model #40185042310, serial #309MM00243 Can you help me
