Our refrigerator went out about a month ago. We used a cooler for milk and food storage for about a week. Ours is/was ll mos old, and still under warranty, but NO ONE that was a factory authorized repair person would come to our little town to fix it. My husband, for some reason decided to unplug it and then plug it back in. I checked about an hour later, and it was getting cold.
Within 4 hours, it was ice cold again. It’s still working great, so I don’t know what was wrong with it.
I called another repair person, and he thought a line had become clogged, and the unplugging somehow helped to thaw the line, or to just reset the motor. I don’t know if unplugging will work for you, but it couldn’t hurt to try it.
Good Luck! Renee
