Frigidaire CRA144HT212 Fuse
In a wall unit, the fuse serves as electric safety net in the rare case of a sudden short or possible overloading of the current. Better to be safe than sorry, always strive to find the cause when the main fuse has blown in order for it to not happen again.
Some warnings of a bad safety fuse
- It cannot power on even when 120V is coming in to the wall unit
- The fused link looks smoky and probably blown at a quick glance
