LG WG1204R Fuse
In a wall unit, the fuse performs as electrical protector in the rare case of a sudden short or any overloading of the electrical current. You should really take the time to find the cause when a fuse blew so you know if something is really wrong.
Main clues the interior fuse should be replaced
- The system will not activate even though enough power is coming in to the wall unit
- The fuse itself looks charred and burnt when first viewed
