Williams 5001912 Fuse
In a wall unit, the fuse operates as a type of electrical protection in the event of a short or overload of the electrical current. It is always best to figure out the main reason a fuse blows so you know if something is really wrong.
Symptoms of a badly blown main fuse

- The main fuse looks blackened and burnt at first glance
