The really bad thing is that the one most affected is the one that runs the 'fridge, i.e., the one that keeps my beer cold. Fortunately, I noticed the problem and reset the GFI.
This is certainly unacceptable and will need to be fixed - somehow.
Guy, There is no NEC requirement for the refg to be on a GFI becuase of the compressor, that's the good news, bad news, run another circuit to the refg, now adult beverage is cold
