Dead GFCI outlet
I have a dead GFCI outlet. Called electrician. Assessment lose connection or broken wire somewhere between breaker box and GFCI outlet. Since this outlet is in kitchen and wires are running behind tile wall I dont want to damage the tiling. What should be the step by step process to find where the fault is in path from Breaker to GFCI?

Trader is right, look for any other load on that circuit that either works with the breaker on, not off or that is dead. Look in that box for a bad connection. Other than that it might be easier to fish in a new wire. Wires VERY seldom fail. Isolate what outlets are on the breaker in question. Check connections in all boxes on the circuit. Connect a lamp socket to the wires in place of the GFCI to tell when the circuit is live. If you need to check actual conductos, detach them from the breaker and connect all 3 conductoes together at the service box, then check continuity at the box from wire to wire. If you have connectivity neutral to ground and not neutral to live or white to live you KNOW the problem is on the Live wire. Pretty easy to pin it down. |

This is one of the two GFCIs in the kitchen. The other one is working fine. GFCI that is dead is on a separate breaker which I have isolated. GFCI is protecting four other outlets. And they are all dead. I opened up all 4 outlets and pretty much checked each of them for loose wire/ connections etc and they all seem to be fine. |

And they are all dead. I opened up all 4 outlets and pretty much checked each of them for loose wire/ connections etc and they all seem to be fine. Any idea where the incoming cable routes from? If it's the first receptacle in a kitchen and it protects others, then good chance the incoming run is from the breaker without another receptacle or switch box in between. Can you find the cable in a basement, going to the kitchen? They have detectors that will tell you if a cable is energized to help you trace it. Or start tracing the cable from the breaker, if that's possible. Any renovations done, where it would be likely that a cable could have been cut, then spliced? If someone did that inside a wall where it's not supposed to be, it could be hidden. Agree with Gfre, if you can't find the problem, the other solution is to run a new circuit to the GFCI receptacle. Just be sure you've checked all other receptacles, lights, etc anywhere nearby to make sure they aren't on the existing circuit, that all that is there are what's downstream of the GFCI with no power. If there are none, then a new run from the panel, or from where you can find the existing circuit, eg in the basement near the kitchen, to the GFCI could be the way to go. |

I hope the OP has the skills to do the testing. How easy this is to fix depends on how accessible the wiring is. If a box with a loose connection can't be found, then like you say, easiest is probably to run a new piece of cable to the GFCI and either cut the existing cable off near the kitchen if that's possible, or run a new cable all the way from the breaker, if that's easier. |

If this is an older house I still would not give up on another receptacle or light in that circuit on the line side of the GFCI and it may be a Harry Homeowner Special in the basement attic or crawlspace. |

Bootleg, outlets lighting or receptacle may be in strange places. That is why I suggested the attic, crawlspace or basement. Look for something out of the ordinary, a plastic box if the rest of them are metal or some staples pulled loose to drag up a little extra wire for a box. When someone is cheating on the 6" "free conductor" thing, it is easy to make a bad splice. |

You don't need to break any tiles for this. Remove the old GFCI. Disconnect all 3 wires from the other end at the breaker / fuse box. Use an ohm-meter on all 3 wires. (Will require an additional test wire from box to kitchen.) Note: To protect ohm-meter, check for voltage before checking for continuity. V. Good point. Always check for voltage first. There should be no voltage. Just one amendment. If the most likely location is teh connection at the GFCI, then there will be voltage there one the wires. Also, it's probably not necesary to remove the wires to check each for voltage, unless the connections are backstabbed and there is no wire showing, only insulation. |

So far this is what I have done: 1. Called electrician - which verified no issues with breaker box but no power at GFCI. He did not do anything else like what others have suggested in forum. Wish I knew about forum before calling in electrician. 2. Tested all outlets in kitchen and surrounding area with and without breaker off for dead GFCI. All outlets are working except the ones on the dead GFCI. 3. Opened up and visually inspected all outlets protected by dead GFCI for any issues related wiring. They all seem fine. 4. Measured voltage at GFCI line - all pairs of hot / neutral and hot / ground measure 52V. Seems like phantom reading. We did not have any renovations etc or any electrical work done. House was built in 2011. My next step is to trace path from breaker box to GFCI and see if anything obvious is on the way. |

For example, if he used a non-contact voltage tester to determine that there is voltage at the cable in a basement, right where it goes up into the walls where the kitchen GFCI is and there are no other boxes around that it could go to. But even then, it's likely easier to just cut the cable there and run a new segment to the GFCI instead of opening walls. |

If so, I'd just start with a non-contact tester and see if you can find the cable where it goes into the kitchen. No need to trace it all the way to the panel if it's live there. Same idea if it feeds from an attic, etc. Since it's new construction, the possibility of a nail or similar damage being done to the cable inside a wall increases greatly. Not likely there is an illegal splice inside a wall, though I suppose a construction guy could have screwed it and patched it illegally. |

Just to be absolutely certain, I'd open the panel and just double-check at the outlet of that breaker for voltage and connections before I went any further afield... I've seen a similar situation (downstream outlets non-functional) that was caused by a roofer nailing into romex that wasn't routed through the center of the stud, but rather was too close to the exterior wall with no nailing plate on the stud. (Second floor; the roofer was nailing new flashing for a short bit of roof over the garage door). |

Yeah, as gfretwell pointed out, that's the most likely cause if there is a break between the panel and the first box (or between boxes altho it appears this is first if OP is correct). -- |
