microwave has no power
Microwave shut off during usage. Totally gone. Tried different outlets, breakers etc. Thank you
Microwave repair is a dangerous endeavor if you don't know what you're doing:
That said, a fuse replacement is a relatively easy fix. (The main fuse should be on the main board next to the power input.) However, a blown fuse is sometimes just the symptom of a different problem in the microwave.
I fix anything and everything that breaks in my house—but outside of a simple fuse swap, I wouldn't try to fix the microwave myself.
