I just got a new fridge and put the old one in the garage. It's connected to a GFCI outlet which it's tripping intermittently. It's not the breaker that's tripping, it's the outlet itself. The fridge is connected to an extension. When I press reset the fridge works again. I know there are issues with using GFCI outlets and fridges, my question is, can I just replace this outlet with a non-GFCI outlet? Would that work? Is the wiring any different? Would it still trip for some other reason? The breaker is 15amp compared with 20amp previously. It's not tripping the breaker so I'm guessing that's not the issue.
Same old deal I have seen for the past 35 years as a service technician. Not one person referenced the owners manual. Any appliance you purchase that has a compressor will tell you in the owners manual to not plug it into a GFCI receptacle. And this goes beyond compressors to include just about anything with an AC motor. While it is true a lot of refrigerators will run for a while on a GFCI receptacle, it is inevitable that at some point the internal lubricant will collect enough metal from friction wear that it will charge the lubricant itself and create a natural current leakage to ground, which, surprise, surprise trips the GFCI. The most common response when you tell someone to read their manual is "I didn't get one" Uh huh. P.S. all compressors are vapor compressors. If there's no vapor there nothing to compress
This can even happen with new fridges. A garage can have high humidity levels by huge temperature changes that effects the electric resistance of the surface between hot terminals and the metal parts that are grounded.
Besides the suggestion to get a new fridge as replacement for an older one, what can yield a ROI in a few months in some places, a good compromise between an electric circuit with an oversensitive 5mA- GFCI and a circuit with none at all is a 30mA- GFCI, which is standard for the big majority of buildings on this planet, even with 230V household voltage.
Since this question did not get closed as duplicate of Why would a GFCI trip on refrigerator circuit?, here is the most upvoted answer from that question that is very much on point in answering this question:
Bottom line: If the adopted codes in your area do not provide an exception for running fridges without a GFCI in your garage, the best you can do is add get someone to add a snubber if you want a legal installation.
Sure the fridge works great for you now without a GFCI in your garage, but will you remember to change out that circuit before you move? How about if the unfortunate/unexpected happens and you don't get that chance? Will the next homeowner think this is a general purpose GFCI protected circuit as it should be in a garage?
