I’ve got some dead outlets in my garage. I know, it should be a flipped GFCI, but the way the circuit is laid out doesn’t make sense to me. And I can’t find a GFCI anywhere on this circuit. I’m a computer engineer and have lots of electrical diagnostic tools, but I’m stumped.
This year, I went all out on christmas lights. They turned out great! However, when I arrived home today the lights were off. Upon confirming the outside outlet was cold (A), I discovered that the outlet (C) for our secondary refrigerator and freezer were on the same circuit.
I was able to confirm the breaker has not flipped. All circuit breakers are closed (hot). I have an attic for the garage, and I can roughly see how the romex is routed. In the diagram below, each number represents where the romex enters/comes out of a hole (presumably to an outlet or another junction box).
The line coming from hole 1 is hot. The line from 2-4 is also hot. However, the line from 2-3 does not have power.
I believe hole 1 is coming from the panel. Hole 2 is above an internal and external outlet. The external outlet is used for the Christmas decorations. Hole 3 is above the outlet for the refrigerator. Even though the line into hole 4 is hot, there are no outlets (internally nor externally) on that side of the garage. I presume they planned to have an outlet there, but never installed it.
All visible outlets (A, B, C, D) on this circuit are dead.
There is a second, one outlet 20A circuit in the garage (outlet E), but that is working fine as expected. Outlet E is a GFCI outlet. No other outlets on the garage are GFCI.
Here are pics of outlets A and B.
Is there anything else I should be checking? What am I missing?
