That probably indicates a fault in the exhaust fan; either a motor winding has failed, or the fan is wired improperly.
Just to amplify - The Ground Fault Current/Circuit Interrupter (GFCI) detects current flowing to ground that should instead be flowing in the fan. This means somewhere in the fan the Hot wire has an unintended path to ground and is a shock hazard. You should check the wiring to the fan (with power off) and make sure there are no bare wires that could be causing your problem and if you don't see anything obvious you should replace the fan.

What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?
In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)
What is the trip time for a GFCI?
The trip time for a GFCI is from 15 to 30 milliseconds.
How many amps does gfci trip at?
GFCI receptacle are designed to trip on 5 milliamps.
Where are GFCI required by the electrical code?
GFCI (or Ground Fault Circuit Interrupter) should always be installed anywhere there is a possibility of the "plug-in" getting damp or wet, such as the Kitchen or Bathroom, also it doesn't hurt to use a GFCI in rooms used by children as they trip much faster on a fault than circuit breakers (if the kid sticks something in the plug in)
Will a GFCI outlet trip when the current is reduced or shut off?
The GFCI is measuring leakage current to ground, so if no current is flowing it won't trip.

What happens if you trip a GFCI repeatedly on purpose?
Every time you trip the GFCI, the power to the device plugged into it will lose its supply voltage.

Why won't the GFCI trip the panel box when shorted?
A GFCI is not an overcurrent protection device. It only protects people from electrical shock. However, if you were to create a perfect hot to neutral short the GFCI would not trip and the panel breaker would.
Can rodent damaged romex cause gfci to trip?
Yes
When would it be a better idea in a residence to install a GFCI breaker instead of an GFCI outlet?
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.
Plugging an electric heater into a GFI outlet caused the lights and other outlets to go out but didn't trip the circuit breaker why?
A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.
Can a difference of 5 milliamperes for 30 milliseconds trip a gfci?
Yes it can.
How much amperage is needed to trip a 20amp GFCI outlet?
A GFCI trips when it detects a difference in the amperage going to the outlet and what is coming back. Even 4-6 miliamps difference will trip the outlet.
