Friedrich US14C30 Fuse
In a wall unit, the fuse operates as a type of electric safety net in the rare circumstances of a sudden short or overload of the electrical current. Smart people try to figure out the main reason the main fuse has blown so you know if something is really wrong.
Symptoms to watch for in a bad fuse relay
- The fuse itself looks blackened and blown when first viewed
- The wall unit will not turn on when power is coming into the unit
