Frigidaire FAS257Q2A3 Fuse
In a wall unit, the fuse serves as electrical defense in the rare case of a sudden short or possible overloading of the current. It is always in your best interest to figure out the main reason the main fuse has blown in order to see any potential danger.
Major clues of a failed safety fuse
- The main fuse appears charred and broken when you first see it
- The wall unit will not turn on even though 120V is being delivered to the unit
