Replacing fuses

There are 3 fuses built into the Barkey warming center III DTM to protect against overcur-
rent in a fault situation. Two fuses are located next to the mains switch on the front of the
heater insert. These fuses are externally accessible and safeguard the entire power sup-
ply.
One fuse is located on the regulator circuit board to safeguard the electronic system. If
this electronics fuse is defective, the entire regulator circuit board must be replaced.
