carpenter in my freezer

for about an hour this morning i was wondering which one of my neighbors was out hammering..and then after following the noise, i realized the noise was coming from our freezer.  it's this constant tapping noise.  i peeked inside and noticed that there was frozen water over some of the food, the tray under the water/ice dispenser was full, there was a puddle on the floor and the ice container was one solid mass of ice. i cleaned it all out and am keeping an eye on it...it's still making the noise.  i'm not sure what's wrong.

there's a part of me that would love a new refrigerator, but the cost would suck...maybe it would be better to get it fixed...but a new one would be lovely too...this is what i want...
