Question about GE Spacemaker JVM1640SJ Microwave Oven
The microwave was working fine, but when I went to use it 10 minutes later, I was unable to touch any buttons. The clock is out, no buttons work, but when the door is shut, the microwave runs constantly. I tried putting some water in the microwave for a couple minutes to see if it was heating, but the water did not get warm, so it seems as just the fan is running, with the interior light on. I tried switching the fuse off and then on to restart it, but it did not make a difference. I can't even keep the door shut, as the machine runs - the interior light also stays on while the door is open. What can I do to fix it?
OK, you will need to replace the magnetron and the touch pad as well. this will fix this issue.

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
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 contact is not through the microwave will not work.
Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely
