How do I locate the fuse on GE Microwave

My microwave will no longer heat food. All the lights, fan, digital readouts, etc. all work. I figure it is either the fuse or the magnatron. Wanted to find and test the fuse, but cannot locate it. I think the fuse is behind the digital keypad, but do not know how to get into it. Any direction is appreciated. Thanks.

I’m not sure if GE is like the jen air but if it is I had to take off the cover and the fuse was by where the main power cord came in. When my fuse blow I didn’t have power to anything.
