Water was dripping from the freezer into the non-frozen area, and the non-frozen area was not cooling

I first disconnected the power cord and then removed all the panels and disconnected the Defrost Heater at the quick-disconnect, and cut the wires on the Defrost Themostat. (The Defrost Thermostat had been replaced about 10 years ago when the Defrost Heater was replaced.) One of the reasons it took longer than 15 minutes was because there was a buildup of ice in the freezer section. I then soldered the wires and covered them with a plastic sleeve and wrapped them in electrical tape. After replacing all the panels and re-connecting the power cord, I restarted the refrigerator. After one week, there is no water dripping from the freezer and everything is working properly. Your diagnosis of the problem was exactly right. Thanks for the info.

Water collecting under the vegatable drawers

I replaced the bi-metal thermostat. Very easy fix. It took a couple of days and the water stopped collecting at the bottom.I am very pleased with the web site.
