LG LAU125HV Fuse
In a wall unit, the fuse serves as electrical protection during the occurrence of a short circuit or possible overloading of the electrical current. Be smart and try to find the cause when a fuse goes out so as to not have it happen again.
Indications of a badly blown safety fuse
- It is unable to power up even when 120V is coming in to the wall unit
- The fused relay looks blackened and broken at first
