I have a GFCI outlet in a bedroom that I use as an office that randomly trips. This is very infrequent, maybe once a month and doesn't seem to be connected to electricity usage on the circuit (computer off, lights off, only the internet box running is the most often situation). It's behind a bookcase and it's a pain when it shuts off and we are trying to use the internet elsewhere in the house.
I'm assuming that the current GFCI is faulty due to the infrequent random nature of the issue, and I feel comfortable replacing the outlet, but I don't see a reason that it should be a GFCI. As stated, it's in a bedroom with no running water or water of any kind. There are a couple of floor mounted outlets in the room so I wondered if that was the reason for the GFCI but that's the only thing I could think of. There is a bathroom on the other side of the wall which I believe may be on the same circuit, but the only outlet in that room is a GFCI, and it never has issues.
