Been troubleshooting this for a week now. After 3 years working perfectly (age of fridge) I noticed the fridge had no power last weekend. The GFCI had tripped on one of two circuits that power my kitchen. I reset it and it tripped again instantly. I got a 12ga extension cord and plugged it into the other gfci protected circuit and it has been working fine. The troubled circuit consists of the line from the breaker to a to a 20a gfci and then runs to two consecutive standard outlets. The fridge is the only device plugged into the circuit. I replaced the gfci and instead of tripping instantly, it now trips every 5 to 10 minutes. Seems to coincide with the cooling or defrost cycle. Tested the fridge on several other gfci protected circuits in the house with no issue. Testing each of the 3 outlets on my troubled circuit shows no faults and I checked all the wiring I can see. I’m out of ideas!

  • GFCIs and fridges sometimes do not work together. It is usually recommended not to have a fridge on a GFCI protected circuit. It might be a problem with the fridge, a problem with the circuit(maybe hidden in walls), or the GFCI just does not like fridges.

  • When it comes to fridges and GFCIs, sometimes you get lucky, sometimes you don't, and sometimes your luck changes for no apparent reason, maybe humidity, sunspots, planetary alignment, etc...

  • Thanks. For me it’s now more about the mystery then what I am going to do about it. I.e. Run a new dedicated circuit. Sounds like I should just chalk it up to gods will. Bet I still cut the wall open. I hate mysteries. Commented Mar 14, 2023 at 20:46
  • I am sure that some electricians will have better/more sensitive testers that most DIYers cannot afford for testing this problem and could find if there is a problem. Away from water/sinks, usually a dedicated circuit is maybe cheaper.

    GFCI name could be misleading. A GFCI actually measures current unbalance flow between hot and neutral and it calls it ground fault if it is unbalanced

As per code:

GFCI protection is only required for kitchen receptacles that serve the countertop surfaces. There's no requirement to GFCI protect receptacles that serve a refrigerator. Unless the fridge is plugged into a countertop receptacle.

Why does the Fridge trips the GFCI?

Any inductive load when switched off, can produce electromagnetic interference (EMI). This interference can, and often does, trip GFCI devices. Fridge compressors have a few inductive loads, that could cause the trip. To prevent that most modern frige have EMI filter.


As far as a fix, dedicated circuit is not, technically, the solution. You can have the refrigerator on a circuit that is part of the rest of the kitchen, just make it not be GFCI protected. The key - dedicated or not - is to place the receptacle in a location where (a) it is more than 6' from the edge of any sink and (b) not in a position to serve the counter.

Arguably, putting the receptacle behind the refrigerator designates it as "not for the counter", but using a single receptacle instead of a typical duplex receptacle will make it 100% clear. A single receptacle may cost more than a duplex, but don't worry because (a) the cost is still very low (at Home Depot currently < $4 for a Leviton) and (b) they are usually good quality (e.g., "Commercial Grade").

As far as dedicated or not, if you are using (as in the original post) GFCI/receptacle rather than GFCI/breaker, simply pigtail the wires for the single refrigerator receptacle off of the LINE side of a GFCI/receptacle rather than the LOAD side and you're all set.

Note that if this is a dedicated circuit with a single receptacle then if it is a 20A circuit then it must be a 20A receptacle. A 20A circuit with multiple receptacles (even just one duplex receptacle) can use all 15A, all 20A or a mixture. Kitchen circuits serving the countertop receptacles must be 20A, so if it is not dedicated and the other receptacles are countertop receptacles then it must be a 20A circuit. If it is dedicated then I see no reason it couldn't be 15A instead of 20A - same price breaker, but save a little using 14 AWG wire.


Because the outlets are just a little bit different.

Fridges shouldn't be on a GFCI circuit, for exactly the reason you're experiencing.
