Williams 2509822 Fuse
In a wall unit, the fuse operates as a type of electrical shield in the rare circumstances of a short or overload of the current. Better to be safe than sorry, always strive to find the cause when a fuse blows so you know if something is really wrong.
What warnings should I watch out for to know if my the internal fuse is in need of a replacement?
- It is unable to turn on even though 120V is delivered to the system
- The interior fuse appears blackened and broken when first viewed
