Electrical Wiring in the Home/Low voltage at GFCI receptacles


I have 2 outlets on a GFI circuit (one outside & one inside, that's in a garage) that both only have 55v but the main GFI reptacle is still 120v. Just a few days ago they were not working & only had 104v while all the others in the house, including the main GFI had 120v so I replaced both low voltage ones which seemed to have fixed the issue. But, they have both lost voltage again & neither is working consistently. This morning they worked again, I'm guessing, after "cooling off". What would be the next step? Bad breaker? Can it still be a bad breaker if some of the outlets on that circuit work consistently and some don't?

Sounds like a bad connection somewhere ahead of where these two outlets are fed from. Could be a failing splice or a loose connection at a device, very possibly one that is working properly.

I think you should call a good electrician. You would be surprised how quickly their experience can help isolate the problem when actually on-site.
