I would have to say that the refer plug u mentioned is also a gfi ,, ck for anymore gfi's ,, u should have one in the bathroom ,, one in the kitchen area ,, and one or 2 outside ,, they may or may not be wired to each other ,, but i would ck each one ,, one by one and see which ones do not have power ,, u have already said that the refer does "not" so imo ,, u have another gfi tripped
btw ,, use the same thing u did on the refer plug ,, the fan ,,
