Friedrich SL24 Fuse
In a wall unit, the fuse operates as a type of electrical shield in the rare circumstances of an electrical short or any overloading of the electrical current. One must always strive to figure out why a fuse goes out to check if you missed anything that may be causing it.
Symptoms the internal fuse has been blown
- The unit will not activate when power is arriving into the system
- The fused relay appears blackened and burnt at first glance
