Fridge is in slide out and had no fans. I added two. Fans are wired separately and has their on in line fuse. The blown fuse wire goes up the back of the fridge and disappears. No way to see where it goes unless I remove the fridge. Dometic CU826E. Has a paper wiring diagram but a lot of it is unreadable and I couldn't interpret anything if it was clear. slow blowing and fast blowing fuses tomorrow. Fridge is now on electric and continues to operate normally. I will be receiving slow blowing and fast blowing fuses tomorrow. I will install a slow blowing because the filament on it appears to be the same as the blown fuse.
