If your attic fan isn't working, you can try to fix it yourself or call a professional. If you're handy, you might be able to fix it yourself by checking the fuse, cleaning the blades, or tightening any screws that are loose. If that doesn't work, it's probably time to call in a professional. There are a few things you should keep in mind when choosing a professional to help with your attic fan. Make sure they have experience fixing attic fans and ask for references. Also, be sure to get quotes from at least two or three different professionals before deciding who to hire.

You can try a repairman, but if it's a big or complicated project, your best bet is probably to call an electrician. They should be able to help diagnose and fix the problem quickly and easily.
