I have the GE JKP86-27" double wall oven (microwave/Oven). Recently, my microwave stopped heating, although it's still functioning. When I key in a time, it works, but no heat or table turning. So I took a flathead screwdriver, and wedged it between the bottom of the door and the frame (lower righthand side)as it to lift the door slightly. The heat started up and the table turned. If I remove the flat head, no heat and no table turning, but still functioning. What is going on?

Sounds like a door switch problem - make sure you check for recall status on your JKP86(othercharacters) particular model. There was a recall involving the microwave door switch(es) on some of these.
