I have a GFCI Outlet in my garage that is tied to two outlets within the garage and two outlets external (front porch and back porch) and lastly to a front yard "lamp" Two or three times a year the GFCI "breaks" and then it takes two to three weeks before it will "hold" the load again. This is very frustrating I think I know how I cause it. I recently thoroughly cleaned my house spraying down the porches, so I figured that the outlets got wet. But that was 11 days ago and the GFCI still trips immediatly after I try to reset it. I do not have anything plugged into any of the outlets in the GFCI circuit and it still wont hold.........I'm wondering if anyone has any "tricks of the trade" that might get me back on track. Should I try to "air" out the outlets on the porches? I replaced the GFCI Circuit a couple of years ago when the electrician told me later that there was nothing wrong with the old one. Does the fact that the "circuit" extends totally around the circumference of my home (full 360) have anything to do with it? Thanks.
