Our 110V Brother Sewing Machine got plugged into the 220V side of our step down transform. After a short pop, it does not turn on. I pulled the power supply board out and it seems like just a input fuse was blow along with the black component which I think is a DIAC from the symbol on the board. The number on what I think is the DIAC is V102210 with ZNR above it. Is the DIAC being used as voltage protector for the machine? Would it be possible to just replace the DIAC with just a jumper? I just wouldn't have any protection next time. I removed the fuse and DIAC from the board.
