Question about GE Spacemaker JVM1640SJ Microwave Oven
Clock sets fine and all the numbers beeb when pushed except for the Start button which doesn't make any sound or start cooking.
Assuming the Start pad on the keypad is good, I would strongly suspect the upper or lower door switch or the switch's mount, depending on your model number.
Even though a door switch clicks, it may still be bad inside.
Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
It's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.
One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.
