Our 110V Brother sewing machine got plugged into the 220V side of our step down transformer. After a short pop, it does not turn on. I pulled the power supply board out and it seems like just an input fuse was blown 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.
