If you want to know how to reset your Samsung Microwave Control Panel, first, take a slightly wet cloth and wipe off the entire control panel. Now, try to use the microwave normally again. Check to see if the microwave buttons require too much force when you press them.
Generally speaking, a problem with a Samsung microwave not working or heating is traced to the microwave being in demo mode. Go into the options, choose option 6, and make sure it is set to 2. Otherwise, make sure that you are not using the kitchen timer by accident.
