Outside GFI Reset button will not push in
Hello, I have an outside GFI outlet & the reset button will not push in, it just clicks & pops back out when I try to push it in. Nothing has been recently changed so not sure why now it would be having issues. I checked the fuse box and the fuse has not been tripped so I am at a loss. I have an outside wall light, could moisture have some how gotten in the box and is causing a short or moisture have gotten in the outlet box? It's strange because like I said there have been no recent changes to anything, would appreciate any suggestions on how I can fix this. Thanks!
