I’m trying to replace the thermal fuses on a fan I found broken, and the damn things keep blowing when I try to solder them. They’re 133° C fuses, and I try to be quick, but no dice. As soon as get the connections, I get my multimeter, and boom, they’re open. I’ve blown two already, fortunately they came in a pack of 10 so I have extras, but some advice would be nice
