The electrical system is protected from overload
damage by fuses. If an electrical component fails to
operate, check the fuse box panel rst to ensure that
a fuse has not “blown.” A blown fuse is an indication
that there is an overload that needs to be corrected.
The fuse panel is located inside the main control box.
