You heated it too long. This is not an uncommon problem, potatoes and sweet potato should only be microwaved from above 4 to 5 minutes; longer than that, the potato begins to dry out on the inside, carbonizes, and then burns – so there’s either a lot of smoke or even a fire.
How do you know if your microwave fuse is blown?
It’s easy to tell if a glass fuse is blown; it will show scorch marks, and the filament will be melted. To check a ceramic fuse, use an ohmmeter or continuity tester. With an ohmmeter or multimeter, you should see a reading close to zero ohms if the fuse is intact, or infinite if it’s blown.
Is it worth fixing a microwave?
