Thanks a lot for advice.

Must not be much of an electrician. Didn't he do the process to find
the bad connection? You have the overhead of the visit, once there
most times they should be able to find it pretty easily, unless something
unusual is going on, like illegal splices that are inaccessible inside a wall.
Plus the electrician should have a sniffer device to help trace the circuit.


Yeah that was pretty much useless. Charged $150 for 5 minutes to tell me what I already knew. Anything further he wanted to open up the wall.

Do you know which breaker it's on? If so, start by finding out what else
is on that breaker. Find out if everything else works or not. Closest
thing that still works, I'd take a look inside there for loose connections.
It's basically tracing the route of the circuit from the breaker to the GFCI
to find where it's disconnected.
Is it just that GFCI, nothing after it that also does not work? What is the
purpose of the GFCI, where is it? That may help figure out what circuit it's
on if you don't know it.

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.

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.
