2. Problem with the membrane switch
Another possible cause of microwave buttons not working could be an issue with the membrane switch. The membrane switch is more commonly known as the touchpad and has a few soft touch electrical switches. There is a certain conductive coating on the touchpad which can go defective with repeated usage. To check this issue and to resolve it, you will need to unplug the appliance and remove the cabinet. Check the membrane switch using a multi meter for continuity. When pressed, it should show a few ohms of resistance. If not, you may need to get it replaced.

3. Problem with the control board
If microwave buttons on your microwave are not working, then another possible reason behind this could be an issue with the control board. If the touchpad of your appliance does not respond but the display lights go on, then this could be the issue. The control board is responsible for generating a low voltage which is in turn supplied to the membrane switch. In case the control board doesn’t generate a low voltage signal then you may need to replace it. to replace the unit, you will first have to disconnect the main power supply and then remove the cabinet and the assembly.
