Most of the microwaves have a grill on the top with screws to access
The control panel. On Samsung counter top microwave oven model MW1150WA
There are no screws. Every once in a while the keypad shuts down. The inside light
Works. After sitting awhile it starts working again. Look at the picture. How do you access
The control pad for cleaning?

Open door and look for screws. Are there any screws under the bottom of the control panel?

No screws inside the door. The bottom has tabs that seem to fit into slots?
Do you think it just pry off?

I doubt it. I just looked at mine. Different but similar in appearance. There are two screws that attach the bottom to the bottom of the key pad. Look under the bottom again.

Okay. Maybe the whole cover comes off

You can't clean those kiey pads, they are sealed micro switches. Yours should be replaced. If the unit is more than 5 years old consider buying a new one
