Can a GFCI fail without tripping the panel breaker?

A GFCI-protected circuit in my garage has failed, but the panel breaker hasn't tripped and the GFCI reset latches. Is it possible that the GFCI has failed?

A plug in tester shows no lights.

If not, what else could account for a circuit failure in a 10-Yr old house?

There's no construction or other work being done that could have severed the hot.

Breakers trip because of a short. GFCIs trip because of current leakage. Two very different things. Check all connections. If good replace the GFCI.

Absolutely.....I change them out all the time. If you can set the GFI then you have power to it. If the receptacle is dead.... then the unit is defective.
