WATER FREEZES ON THE BOTTOM OF THE FREEZER
I have an LG armoire style fridge/freezer and it had lots ice in the bottom and would eventually drip onto the floor. The problem was with the defrost controller. The moisture that enters the freezer when it is opened condenses and freezes on the freezer coil/fins. There is a heating element that sits under this coil which gets turned on by the defrost controller to melt the frost/ice. As the frost/ice melts it drips into a metal tray which channels the water to a drain hole to have it drop into the drip tray underneath the unit for it to evaporate. The problem is that the before the water has time to leave the freezer, it freezes thereby plugging up the drain hole and thus causing subsequent defrost cycles to have the water flow into the bottom of the freezer where it freezes. Eventually the bottom of the freezer fills up with enough ice for the melted water to flow onto the floor. I had my defrost controller replaced (just outside the warranty period!) and it worked for about 1-month and then same thing happened again. Instead of paying for another defrost controller that would probably not work 100% my serviceman used the old paper-clip trick. He took a paper clip, stretched it out and then wrapped one end around the heating element and placed the other end into the drain hole. Thus when the heating element comes on the paper clip keeps the drain hole warm/hot and prevents the water from freezing. It has been 9 months since this fix and I haven't had any ice pooling in bottom of the freezer.
When I had the problem and started diagnosing it I opened up the freezer, pulled out the racks, draws, and eventually the door. Then I removed the ice maker and then a few screws and carefully removed the back white wall panel disconnecting the fan and any other electrical connections. Behind the panel you will see the cooling coil/fins, the heating element, the drip pan, and drain hole. Most likely you will see a sheet of ice everywhere. The best way to remove the ice is to boil a bunch of water in a tea kettle and slowly pour it on the ice to get it to melt so that you can start breaking out the pieces. Have a sponge and bucket ready to remove the water as the ice starts to melt. Eventually you should get all of the ice removed and get the drain hole unplugged. After all the ice is removed, you still need to fix the real problem by replacing the defrost controller, using the paper clip trick, or both.
