This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.
Even though a door switch clicks, it may still be bad inside.

Hi,
Press
the "Off/Clear' button to cancel anything on the display, and reset the
microwave. This is a soft reset and will simply get you out of any
program you have started. Press it when the cooking complete reminder
appears on the display.
Perform
a hard reset. Pull the plug out of the wall power supply, and wait a
moment. Plug the GE microwave back into the wall power supply to reset
any anomalies with the microwave's memory. You will need to reset the
time of day if you perform a hard reset.
Reset
the time of day. Press the "Clock" button, and turn the dial to set the
hours. Press the dial to enter. Follow the same procedure for the
minutes and a.m. or p.m. Press the "Start" button to start the clock.

I would think the small fuses You mentioned may be just for protecting the board. Is it possible there is another fuse and fuse holder inside the unit. I would remove the outer cover and follow the power cord to a main fuse holder. If it went out when you opened and closed the door, you may have a bad door switch that caused the fuse to blow. Check all of the door switches while you have it open.
Also, had you cooked in this for a long time before it went out? It is possible the main fuse got hot due to bad onnections at the fuse holder and melted the fuse. May need a new fuse and fuse holder.
