We've been having trouble with our refrigerator shutting off and then coming back on. We noticed ice cream getting soft and put it in a bowl to prevent a mess, and an hour later it was frozen again. I cleaned under the refrigerator and got rid of a "herd of dust bunnies", I don't think the former owners ever thought to clean under the refrigerator. We had a repair man look at the problem, but he couldn't find anything wrong. I'm pretty handy but don't know much about appliances. Does anyone know a relay or switch I should check or replace?? Your help is greatly appreciated.
