/diy/ - Do It Yourself

>>1541759
Thank you for the help. The circuit does have a fuse, it blew when he applied 220VAC. So he replaced it and then plugged it in to 110VAC and it blew again. That's when he asked me to see what I could do, i'm pretty new to circuit boards and their components, but I figured this was a chance to learn a bit.
He did not say what amperage the fuse was rated for, and he removed it from the board before giving it to me. Here is a picture of the board. I suppose it would be safer to scavenge around for the proper valued varistor instead of risking using a smaller one. I think I'll replace the safety capacitor while im in there, since I found another in an old microwave.
