    Maybe I'm in the wrong forum but I'll go ahead and post in hopes that someone with enough electrical knowledge can reply.

    I have a bathroom fan in the main bathroom and one in a half bath. Lights and GFI outlets work but the fans don't.

    I inspected all of the fuses and they're good.

    I wonder where the problem lies.

    Any help would be appreciated.

    Do the fans humm when you turn them on? They could be corroded and the motor shaft has seized. Or, the switches are bad, or someone disconnected them. Checking out the switches is fairly easy if you have a test light or a multimeter.

    You should have power on one side of the switch, and when you turn it on, you should have power on the other side. You might need to go into the attic to check for power at the fan itself. Sometimes you can access the connections from below, sometimes you can't.

    Did you plug the fan motor power connector into the receptacle?

    Did both fans stop at the same time?

    Are they tied into dehumistat switches?

    Has there been any other electrical changes recentley?

    If there is a timer or switch does this have power?

    Need way more information even to guess.

    Plug the fan motors into an extension cord. If the fan runs you have a bad switch, wire, or connection. If not, then you need new motors.
