What Oneilkeys says could explain the 5 amp fuse blowing randomly.....especially when under way and the coach is moving. Why does the slide not work when the 5 amp fuse is blown though......especially when the slide controller is powered by a 30 amp fuse (typically – I assume the same in your coach but perhaps not). That’s why I was asking previously about checking for power at the slide controller unit, when you pull and replace the 5 amp fuse......might also try the 30 amp fuse too to see if that connects power to the slide controller as it should.
