Recently I have had an issue with my bathroom in that when I turn my ceiling fan on, the ALCI plug on a hair dryer trips. The hair dryer is off and is plugged in. This happens intermittently every day. One day I turned on the bathroom exhaust fan, and I heard a screeching noise; this only happened once about 1 week ago.

Since then I have replaced the switch that operates the ceiling fan with a new switch. I replaced the ceiling fan with a new fan. I replaced the standard outlet where the hair dryer is plugged in with a new GFCI outlet.

I’ve test the connection on the GFCI outlet, and it is working properly. It is also a stand alone outlet; there is nothing downstream from it. The GFCI outlet and breaker never trip.

I’m getting a new hair dryer, but I’m still wondering if there is some other problem. There is some sort of current leakage, but I don’t know where or how to test for it. Any ideas would be greatly appreciated!
