Good evening. I have a house that won't go away and hopefully someone can shed some light on what might be happening.
One of the GFI receptacles in the kitchen trips at odd times. I've replaced the GFI rec., gone through the whole circuit (taken everything apart with no continuity between grounds and neutrals). The breaker never trips, just the receptacle.
I've been over there a number of times and can't find anything wrong. The GFI resets everytime. So, the homeowners were out of town for about a week and left me a key to repull the circuit from the subpanel. Before I cut into the wall I decided to check everything one last time. I went through the whole circuit with the same result. I then went to the subpanel and took the neutral and ground from the main disconnect out. Then I tested the ground and the neutral bars and they still had continuity between them. I found the electric range to be where this continuity is coming from. So, I thought, Aha! Sure enough, the ground and neutral on the range are bonded somehow internally. That sounds like a problem to me. Correct me if I'm wrong. So, I left the range unplugged for that entire week. I went back three different times to check and that GFI was never tripped. I thought "problem solved."
The homeowner just called and told me that the GFI has tripped again. Of course, the range is plugged back in. I don't know for sure if the range is the problem or not. I just know that I don't know what it is if that isn't the culprit. Any thoughts?
Sorry for the long story. Thanks for any input/jokes/critisisms/whatever.
