If the fuse blows when you open the door, the door interlock might be malfunctioning. If the door isn’t properly closed, microwaves could leak out. The oven will disable itself rather than let this happen. This is a tricky repair, involving multiple small components, and best left to a good repair shop.
Why does my GE microwave keep blowing fuses?

What would cause fuse to keep blowing?
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through.
