GFCI & Exhaust fan/light combo

First, I am new to this forum so don't bite my head off for starting a new thread. I am already stressed/frustrated with my situation.

Ok on with the issue.

Scenario: New 20amp circuit from panel feeds (wired in order) a GFCI receptacle, vanity light switch and dual switch for combination light/exhaust fan.

Problem: Everything works fine with one exception; turning off the fan switch, intermittently trips the GFCI receptacle shutting down power in the bathroom. The circuit breaker at the panel is still on. I replaced the dual switch for the light/fan twice thinking the switch might be defective. Still I get the same results. It also makes no difference whether the light to the fan is on or off.

I would appreciate any help walking through the wiring to make sure I have all wired correctly.

Thanks.

 

Welcome to the forums. Would you please give us derailed description of the wiring at each fixture box so we can better help you.

Is this a proprietary switch for your fan or a standard duplex switch? Is it wired with 12-2 or 12-3 or 12-4?

 

A switch should not have any effect to a GFCI since a GFCI reacts to an imballance between the hot and neutral wires. There are no neutral wires attached to any of the switches correct.

Unless it is required in your area, or you want it this way, it is not required to GFCI protect your lights or fan in a bathroom. You may run the feed off the "Line" side of the GFCI if you choose.

This is the right thing to do. Attaching a question to a previous post makes things quite confusing. Well done!

 

I have a sketch already drawn that I will modify slightly and post it. It will be easier than trying to write it.

 

Other than the neutral connected from the panel to the GFCI, all neutral wires are connected together. As I posted to Ray2047, I will be posting a sketch of the wiring. Thanks for the reply.
