Hello - I have a GFCI (Ground fault circuit interrupter) receptacle in the garage that has been "off and on" the past year or so. Every 3 months or so, the Reset button will pop out and needs to be reset. I realize that this is what they're designed to do in certain circumstances, but I'm not entirely certain how they work. In other words, the circuit this was on did not trip, just the GFCI outlet itself. Only a freezer was plugged into this outlet(not overloaded), etc.
Nothing happened such as dropping a dryer in the tub or anything. I'm not being facetious, I just don't know exactly how they work or when/why they trip. My problem is, this past time it shutoff, it would not reset at all (push test, pushed reset button back in, would pop back out after 5-10 seconds) Whereas in the past, reset buttons pops out, it would be fine once the reset button was pushed in. This time, it was stubborn. After trying it several times, it finally stayed in the next day this time. Any suggestions as to what could be the cause?
I read a tiny imbalance in the power and neural line will trip the GFCI, and an imblance indicates the possibility of a current leakage -- but what does that mean in laymans terms? What do you reccomend? A professional electrician to replace the outlet? And lastly, why would it reset immediately when it tripped before, but take more than a day this time before it would accept the Reset button staying pushed in? Thank you in advance for your reply.
