Customer complaint is still no ice production. Found more Frost buildup and evaporator fan was frosted up and not spinning causing high temps resulting in no ice production. Defrosted fan and it works properly. Called tech line to figure out why ice buildup is happening. We found the glide for the top rail is missing possibly preventing door from closing properly all the time. Ordered new rail and customer is to make sure the door closes properly till I return and will check for further ice buildup then; ordrng 1 7011163 (Glide)
