Last night we kept hearing funny noises in the house but couldn't locate the trouble until our son went to get some ice cream. The entire freezer was coated in ice. Being late, I shut the icemaker off and came back to it this AM. I got MOST of the ice out, using a hair dryer and spatula (there was a big sheet on the bottom of the freezer). Then I tried to "defrost" the icemaker as I've had troubles with it seizing up before, though never involving flooding). It's back on now, and I'm waiting to see what happens.
A little background. We had a power outage that lasted 26 hours before Christmas. Since then the icemaker has made at least two full bins of ice.
