The light in my bathroom and GFCI outlet in the bathroom are not working, but the fame which is controlled by a switch in the same panel as the light switch is working. So I know power is getting to the bathroom. The GFCI will not reset.

Is there a issue with the connection for either the outlet or the light which is causing an issue with the other one? I thought it could be the fuse but with the fan working does that not seem to be the issue.

Thanks

They may be in the same panel or box but may still be getting power eslsewhere. For example, the power may come to the box and power the switch for the fan, the hot line then runs to the GFCI outlet to give it power and then to the light. If the GFCI outlet is wired like this the fan will run but your light and outlet will be dead. GFCIs do go bad so you need to use a tesre to insure power is reaching the GFCI via the incoming black wire.
