Hi guys,
Need your help here:
My friend's wife got a new sewing machine from the states (we live in the EU), and pluged it directly to the wall...
I opened it up and replaced the blown fuse, but while plugging it back to the socket (via ac-ac adapter this time), the magic smoke appeared.
I opened it up once again, and fond out that the MOV blew up...
the voltage in the adapter was 120VAC.
my questions:
1. Is it possible that the MOV was damaged during the first operation?
2. As the MOV is unidentifiable, and no schematics are available, what MOV should i pick for replacement?
Thanks in advance,
Jonathan
