LG Bottom Freezer Frost Issue

It sounds like your defrost controller has gone bad. I have an LFC25760 and had ice build up in the bottom of the freezer such that water would start leaking onto the floor. The ice build up in the bottom of the freezer was due to a failing/bad defrost controller. Behind the back white wall in the freezer compartment exists the cooling fins along with a heating element underneath. Due to moisture that comes into the freezer from opening it, frost/ice builds up on the cooling fins. Thus the defrost controller turns on the heating element to melt the ice/frost off of the fins which then drips into a metal pan which channels the water to a drain hole which drops into the drip pan underneath the fridge next to the fan. The problem is that the defrost controller doesn't keep the heating element on long enough or the cooling cycle comes on too soon thereby freezing the water and plugging up the drain. 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.
