Comfort Aire REG-123A Fuse
The fuse performs as electrical defense in the event of a short circuit or overload of the current. You should really take the time to figure out the main reason a fuse goes out in order to figure out if there is a major problem elsewhere.
Symptoms your fuse has gone bad
- The main fuse looks blackened and unfused when initially viewed
- The unit will not turn on even though enough power is arriving into the system
