Have a GFCI that is constantly tripping with nothing plugged into it. Thought maybe the grounding wire was hitting the hot terminal or something but it's wired with stranded THHN directly into the holes. I hit the metal box with a hammer (lightly) and it tripped the GFCI. Defective?

I've never had this problem before with a GFCI... It is on the other side of a laundry room.. could be vibration from the washer or dryer. but that seems a little too sensitive

Does the GFCI have any downstream loads? Remember they trip between 4 & 6 ma of leakage. Even a long run of fairly good wire , on the load terminals, can trip one.

And yes, the failure rate on a GFCI is high. Change it out just for grins and to save your sanity.
