yep, we had to do this ourselves this summer. Load frozen stuff in a good cooler with ice, turn off frig, open only the freezer and lay a towel on the bottom. we used a hair dryer on low outside the freezer blowing in. Melted the ice pretty quick including the icemaker. Dry the freezer, close door. turn on frig and when freezer is starting to cool load it up with the frozen stuff. As long as you don't open the refrigerator door it stays cool. took us about an hour.
