This is a 10 or 12 year old Panasonic micro.
In the middle of heating several different things sequentially it suddenly quit working.
But not entirely. The clock worked and the light worked. The timer counted down as usual but there was no heating and the turntable didn't rotate. While I was contemplating replacing it, the wife said she slammed the door and it started working again.
Maybe some thing was loose. I pulled the cover and did a visual inspection and everything looked tight and in place.
Is this behavior indicative of a microswitch not getting activated?
Perhaps a bad switch or the interlock parts have become worn. The switches look replaceable, the plastic parts of the latching and interlock functions were probably made for that particular model and are unique.
