GE AZ41E09DACW1 Fuse
In a wall unit, the fuse works as electrical protector just in case of an electrical short or possible overloading of the electrical current. It is always best to figure out why the main fuse has blown so you do not have to keep wasting fuses that continue to blow.
Indications of an obviously blown safety fuse
- The system will not power on even though 120V is arriving to the unit
- The fused relay appears charred and in rough shape when you first see it
