The unit shuts down after 2-3 seconds because the magnetron isn't pulling any power. This can be caused from a bad magnetron, bad inverter board or one of the 3 door switches failing. Now since the light isn't coming on when the door is opened, it sounds like one of your 3 door switches has failed so below is a video that shows you how to test the door switches on a Whirlpool microwave. Panasonic isn't much different at all and the actual testing is the exact same. CLICK HERE for video We are on the honor system here. Please remember to rate my service before you leave today.
