Robert H for Model Number gss20iembcc My freezer is -5 my fridge side is 60. I replaced bad defroster heater and the thermal switch. This unit is building up ice on the bottom and freezing solid over the drain hole. I removed the back cover and the coils are not frosted up and the fan does run fine. The freezer is holding - 5 set on 4 the fridge side stays at 50-60 no matter where I set the control. I am getting plenty of cold air blowing through the bottom meat pan air control. I can turn this off for 2 hours then plug back in and it will work fine for a day or two.

The damper is in the upper left corner. If not then the issue would be caused by a faulty damper assembly and would cause back flow which would cause the drain to freeze. Read More...
