Williams 3509622 Fuse
In a wall unit, the fuse works as electrical defense during the occurrence of an electrical short or possible overloading of the current. Be smart and try to figure out the purpose as to why a fuse blew in order for it to not happen again.
What symptoms are present when the Williams fuse really needs to be replaced?
- The interior fuse appears blackened and unfused when initially seen
- It refuses to power up even though 120V is arriving to the unit
