I have an almost 3yo Bubble King Double Cone 180 powered by a Red Dragon 3 Mini Speedy. I did some quick maintenance in the sump today, and turned off the skimmer. When I later tried to turn it back on, nothing happened (small display on unit shown below is dark). I thought maybe a fuse was blown and started opening the cover, but then noticed that one of the screws were sealed.

Although the unit is almost 1 year out of warranty, I would rather not brake the seal if there is no fuse available in the first place... anyone know?
