Hello everyone. New to this forum. I have a B&W ASW610 subwoofer. The 4amp replaceable fuse blew and I tried another fuse ( same spec) and it blew again. I decided to open it up and found that an internal fuse on the ICEpower 200ASC board had blown. My concern is this, I don’t know the value or the type of fuse I need to buy, as well what caused this fuse to blow. I do not see any other visible damage on the board. Thanks is advance I have posted pics.

I can't quite follow you to be honest. The main onboard fuse is in the brown plastic thing near the AC input, the spot with damaged silkscreen looks like a blown 1812 SMD MLCC. So is the fuse in the brown thing blown?

Going by current practices in SMPS ( smaller is better ) and noticing the use of SMD components and the small area of the fuse I would think its a SSF= solid state fuse in SMD form its just working out the current rating .

The pictures are quite high resolution. Still looks to me like an SMD MLCC said goodbye, as in blowing up and failing short circuit. Probably took some other stuff with it, who knows. Even assuming you figure out what component is supposed to go there and manage to replace it, I would suggest checking all the power semiconductors before hooking it up to mains again. But I also know little to nothing about modern SMPS design, so take that into account 😉

@smatlewis did you ever solve your problem , I have the exact same board and component problem !
did you figure out which component it was ? or did you buy a new board ?
I am situated in Europe and have a hard time finding suppliers if a new board , oddly enough since ice power was developed Appomattox away from where I live
