I am original owner of 1986 house where the refrigerator was put on kitchen GFCI as it is 5' from the sink. I lived there 25 years and never had the GFCI trip for any reason. I had GE fridge, then Whirlpool fridge, then Samsung fridge.
18 months ago I gutted the house to bare studwalls and renovated it for a rental. With the walls open I had an electrician inspect the panel and all wiring, and had him replace all the GFCIs just because of age. I also asked him about a dedicated non-protected circuit for the fridge but he said it wasn't allowed because of being 5' from the sink. So he left it on the GFCI.
The first renters experienced one nuisance trip in over a year of renting, no idea if their fridge or something else caused it. The new renters' fridge, however, is tripping the GFCI several times a day (we have narrowed it down to the fridge). Their fridge is less than 10 years old and works fine on an extension cord to non-protected outlet as a temporary measure to preserve their food.
I'm replacing the GFCI just because it has been tripped so much. I doubt the existing GFCI is faulty but I guess we'll see after I replace it. If the new GFCI continues to trip, is there anything else I can do for them? Thank you for your help.
EDIT to add: The fridge is on the last outlet in the circuit. In other posts I saw mention of a "snubber" - is that something I can add to the fridge's outlet and would it help stop the fridge from tripping the GFCI?
