a 75kv 750mA fuse has blown in my micowave (sanyo em d953)do these blow because of the age of the machine or is there another reason
The fuse can blow from a power surge, caused by lightning or inconsistent power service. They can also blow from a direct short in one of the other components. Replace the fuse, they are cheap. If it blows again right away, you probably have a direct short in the microwave.
Did you know (true story) when microwaves first came out the companies selling them employed a scientist to do a report on them to see if they were safe. He tested them thoroughly, and announced that yes, they were safe. Then went home and threw out his microwave. This is a true story.
