GFI Outlets and GFI Breakers
Yo Dawg

Who was the electrician? Xzibit???

Because putting a GFCI in another GFCI's protected zone is rather silly. 

Speaking of silly... 

Refrigerators and GFCIs

You want a refrigerator to last a long time, so they want to hermetically seal the Freon stages so the Freon doesn't leak out.  But how do you seal the piston rings of a compressor?  By putting the whole compressor inside the freon tank.  But then, how do you seal the shaft of the motor? By putting the entire motor inside there too.  So you have a steel jacketed motor swimming in Freon inside an aluminum tank, stuffed in the bottom back of a fridge that's entirely wrapped in steel and grounded.   You have no chance of touching the Freon tank, let alone the motor, and you're not likely to drop it in the sink.  Does this sound like the use-case for GFCI?  No.  No it does not. 

Now, an AC induction motor is (as you might guess) a very big inductive load.  Inductors, when disconnected, must continue to flow current, and will increase voltage to infinity until they do. This plays badly with GFCIs, as you might imagine. 

This is the classic "safety system versus safety system" scenario, like a low-oil-level trip on a fire pump: saves the $50,000 engine and lets the $50,000,000 warehouse burn down.  The well-meaning GFCI poisons all your food. If the trip isn't noticed by the right people, someone might just reset it and no one's the wiser. 

This is a big problem that is well known to the industry. 

GFCI does not belong here.  The Fridge should be removed from GFCIs entirely.  In many common freezer locations, this isn't quite legal because of a general Code requirement to have GFCI on receptacles in those rooms.  So this will require a nudge and a wink from the local inspector; or; he doesn't need to know about it.  

So change the duplex GFCI receptacle for a simplex plain receptacle, and label it "Dedicated for freezer". That is making a fair effort to assure the receptacle isn't used for anything else, and that will satisfy many inspectors, who perfectly well know the problem of refrigerator GFCI trips. 



You should now have a surplus GFCI receptacle and breaker.  What to do with those? Find another circuit that does not currently have GFCI protection, but could use it.  

By the way, do the same thing in your kitchen. De-GFCI your fridge.
