Re: ge spacemaker microwave oven
The keypad is defective. GE calls it the "membrane switch".

I have the same problem. It was/is a wiring issue behind the key pad. I unplugged the microwave and took the vent and key pad covers off - heed all warnings. Using leather gloves and needle-noze pliers, I removed the wire ties and reposition the wires. I also checked the plastic connectors for looseness. It's currently working, but for how long who knows. Mine is 3+ years old. I will never by another GE product.
I suggest you don't tackle yourself as the capacitor can hold thousands of volts even w/ the unit unplugged. Be careful.
If you have an "options" pad, press that and you should be able to get to the message sub-menu. If not, you may have gotten too much moisture in the key pad when you cleaned it and it will either need to be replaced or might possibly return to normal after drying out completely for a few days
I have the same problem on my oven- model JVM1640WB and called an appliance repairman who is honest and reliable (I've used him before). He said the problem is with the electrode, to fix it is roughly $300. He recommended buying a new microwave rather than fixing it.
hi possible magnetron problem but also check highvoltage capacitor and diode . the process of ellumination is the only way to help u .first disconnect connegtor to magnetron and switch oven on if noise goes away eureka repeat with other components
