Ground fault

I have a ground fault outlet on each circuit in my coach, but I keep frying the one in the bathroom. Happens when the circuit is over loaded usually by my wife's hair dryer. My question is why does the ground fault pop? The breaker does not trip. Could this be caused by the wrong amperage ground fault outlet?

    The obvious test is to plug the dryer into another circuit that is protected by a different GFI. If the GFI fries or pops, the dryer has a problem.

    I suspect it isn't an overload, hair dryers are rated to run on a 15A circuit. I suspect it senses a ground fault. NOw for question #2. Most all hair dryers now also have a GFI on the plug. Does that ever trip?

    You said in one place the GFI gets fried, in another place it pops.

    If it pops, opens the circuit, the hair dryer may have a ground fault. If the GFI gets fried, maybe the dryer is drawing too much current. I think most GFIs are rated at 15 A.
