Question about GE JVM1440 Microwave Oven
We have a GE combo microwave. Start from today, the turnable starts to turn when the door is open but stop when the door closed. It still cooks.
Major concern is if the turnable turns when the door is open, is there microwave leaked out? Can I use it since it still cooks.
What could be the cause of this? Is this some thing DIY?
Thanks for the photo of the label!
It shows the FCC ID number, which I used to find schematics at the FCC Web site.
The problem is a shorted primary interlock switch.
This is the door switch which has two black wires connected to one terminal and a black and a blue wire connected to the other

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides.Since the table turns without a program start and If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean,solder and reset the board.

If one of the door interlock switches
is not switching properly or there is a condensation problem on the
sensor control panel, either can cause the turntable/light/oven to
come on even though the "Starts" button has not been
depressed due to the wiring of the switches.
Check for faulty door switches and/or contaminated actuators.
I hope that helps.
