both bath recept. and an outdoor receptacle do not work.I checked breaker box and reset gfci. Still all dead. Can a gfci breaker go bad?Should I get a replacement? How do I remove and replace breaker? Thank you.

 

Do you really have a GFCI breaker? I.e., is there a "test" button on the breaker itself? Or do you have a GFCI receptacle?

Yes, all of the above can go bad. But first, go press the "R" or "RESET" button on every GFCI receptacle in your home. Be very diligent in your search to make sure you find them all, including the one behind the freezer or storage cabinet in your garage, the one in the back corner of the basement, the one in the closet, and the one on the outside wall in the backyard.

Replacing a breaker is not a job for a novice, since the danger of death is quite real. Replacing a receptacle, however, is an okay job if you shut the breaker off. When replacing a GFCI, you have to pay very close attention to "line" and "load". This is explained in the little bitty print that comes with a new GFCI receptacle.

Don't just "check" a breaker. If you have no power on the circuit, switch the breaker off and back on again. You can't always tell by looking at a breaker if it is tripped.

There are some other possibilities. You may have a continuing ground fault. Turn off every switch on this circuit, and unplug everything from every receptacle. Then try to reset all GFCIs again. Even so, you may have some moisture in one of the receptacles on this circuit (the outside ones are most likely, but of course bathrooms and kitchens have a lot of moisture too). In this case, you won't be able to reset the GFCI until it dries out.
