Williams 4007731 Fuse
In a wall unit, the fuse operates as a type of electrical defense during the occurrence of a short circuit or overload of the electrical current. It is always in your best interest to find out why a fuse get disrupted so it does not happen again.
What are the indications that my fuse relay needs to be swapped out?
- It cannot activate even though electricity is coming into the unit
- The fused relay appears blackened and probably blown when first viewed
