I've been repairing a lot of small appliances lately, and the most common cause of failure has to be thermal fuses.
I have a old electric fan from the 1920's or 30's, and it has no thermal fuse. However, all modern day fans seem to have such a fuse, and it's usually rated pretty low, like 115 degrees, etc. Well, here in Texas, it sometimes gets to be 110 degrees in the shade, so naturally the fuses aren't going to hold up.
I replace them with Radio Shack 224 degree fuses, and that seems to solve the problem with ease.
Anyway, I just wanted to know if anyone knows about the laws concerning these things. I'm guessing they were added to prevent melting / burning plastic, which I believe melts at around 250 degrees or higher.
Any insights would be appreciated.
Thanks,
Gary
