Thanks for the response. That seems like an easy enough solution --
Unplug the unit for 24 hours to allow it to fully defrost; then mop up all the extra water. Is that right? I guess my only problem is what to do with all the stuff in the frig and freezer while it's defrosting? Can it stay in the frig?
Unfortunately no. The frozen foods will help to maintain a low temperature and prevent a complete defrost. Best suggestion is coolers to store the food overnight, or maybe a friend or neighbor might have enough room to help you out.
Okay, thanks -- I'll give it a shot.
