Refr drain ices up completely in about 2 weeks, with the ice buildup contacting the fan, and then stopping the fan.(lots of noise first) Service replaced the timer to no avail. They now say that the styrofoam is saturated
and all needs to be replaced. When opening it up and looking at it myself, I can,t see why that would be the problem, as the drain spout goes right up to the drain tube, which isn,t plugged.
