Williams 3501522 Fuse
In a wall unit, the fuse serves as electrical protector in the case of a short circuit or possible overloading of the electrical current. Always play it safe and attempt to find the cause when the main fuse has blown so you can see of there is a bigger problem.
Important hints the safety fuse needs replacing
- The internal fuse appears charred and burnt when first viewed
- The wall unit will not activate even though electricity is delivered to the system
