Robgrr for Model Number PFSF6PKXDWW Regarding the question and answer I pasted below....It is the fridge side drain I was speak about and the frozen drain hole is what the problem is. The defrosted water has no where to drain because the hole has an ice plug in it and therefore draining into the fresh food section. Any idea of what I can test to see why the drain keeps plugging up creating an ice shelf behind the ASM door? Could it be a sensor or possibly the Heater Metal Sheath, although I would think the entire evaporator itself would be a complete block of ice if the heater wasn't working? The ice is only forming below the evaporator and covering the drain hole. Thanks -------------------------------------------------------------------------- Question: 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? Model Number PFSF6PKXDWW 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.
Answer Robgrr, it is likely that the drain tube WR02X12751 has a residue on it or it has broken down to where it is remaining pinched shut in the duckbill. This would cause the water to not be able to drain properly. Read More... Answered by AppliancePartsPros.com | Friday, April 10, 2020
