If the microwave buttons don't work the touchpad and control panel assembly are probably defective.

touchpad might be at fault. Generally speaking, if the
display is working and some of the buttons respond correctly but some
don't, the problem is with the touchpad.
User Control and Display Board
If the microwave buttons don't work the main
control board is most likely defective and will need to be replaced.

A bad keypad may be worn out due to age, damaged, or it may have gotten wet or otherwise contaminated. Moisture and contamination can be caused by not using the hood fan when boiling on the stove top, spraying of cleaners, by storing the microwave in an unheated garage or shed, or infestation. I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller. Apply an alcohol-based cleaner (such as the purple kind) to a cloth (since paper towels can scratch) and gently wipe it off. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics.
