I have a freezer in my garage that is plugged into a GFI outlet.
I was told that this was not a good thing.
Would this be an easy fix by changing out the outlet, or should I move
the freezer which is a lot of work?
Thanks in advance.
That appears to be one of those things where if you don't have a problem, I
wouldn't sweat it. It won't damage the freezer. Theoretically, high humidity or
the compressor start can trip the GFCI outlet. This can lead to spoiled food if
you aren't in the freezer often.
If you haven't been having a problem with GFCI trips, you may not need to do
anything. If you have and the outlet is a GFCI outlet, replacing it with a
standard outlet is easy to do.
If the outlet is a standard outlet protected by a GFCI breaker or a GFCI outlet
that is further upstream, you can either move the freezer or get someone to run
a new circuit to the freezer. Electrical work in garages is pretty
straightforward, so hiring someone to add an outlet shouldn't cost you a lot.
Never put a freezer, refrigerator, or anything that must run all the time on
a GFI type outlet. Those outlets or breakers sometimes trip for no real
reason and can let your food thaw. Sump pumps and such can trip them and
you get a flood.
At the very least, don't remove the GFI if it protects other outlets
I've had some GFIs that falsely tripped once a month, others that
never did even with motors or straight fluorescents were on the same
circuit. A hash filter (EMI filter) wired ahead of a GFI should
eliminate virtually all false trips in even the noisiest environment
(a hash filter between the GFI and refrigerator can prevent false
trips from noise generated by the latter), and GFI chips have turn-off
time delays to minimize them as well. UL standard 943 allows for a
delay of as much as 5-6 seconds when the leakage is under 6mA but
requires turn-off within a couple 1/100ths of a second at 100mA.
