Robgrr for Model Number PFSF6PKXDWW Ice keeps forming plugging up the defrost drain hole even after I have installed a new drain clip AP5579885. Each time I melt the plug up I ensure the drain is clear and water is emptying freely into the pan, yet 24 hrs later the drain hole is completely frozen and plugged up again. There is no ice forming on the evaporator that I can see so why would ice be forming only in the drain hole and line and freezing up so quickly?
Answer Rob G, It is normal for the freezer drain to freeze over during the cooling cycles. The defrost drain clip assists in thawing the top fo the drain for the defrost cycle so the water can flow. This only becomes a problem if it doesn't thaw and the water can't drain. Read More... Answered by AppliancePartsPros.com | Friday, April 10, 2020
