Expert: Robert Wilber - 10/26/2009
Question
I have a gfci that began tripping with no obvious explanation; no new changes on the the circuit, no hair dryers or tools or anything like that. I unplugged everything that was plugged into any of the outlets on this circuit and the gfi kept tripping. I checked the panel it seemed unaffected in that the circuit breaker in the panel had not tripped. I replaced the gfi because it had been 20 years since the building was built so I wanted to eliminate the aging factor. The new gfci tripped immediately upon switching the breaker back on and resetting the new gfci. This is still with everything unplugged from all of the outlets on this circuit. I am perplexed as to what is going on and, more importantly, how I can fix it. Thanks for helping me with this problem.
Answer
Hang any new pictures?
Install any new molding?
Basic troubleshooting is required.
Something finally caught up with your circuit, a conductor pushed through insulation or such.
Pull everything after the GFI out of the wall and look for the problem.
Remember that a grounded neutral will trip a GFI.
Good luck
