Jay for Model Number pss29ngmbcc Back of icemaker freezes up and freezes the icemaker crusher dispenser motor that makes cubes or crushed ice. I have replaced the Defrost limiter thermostat but it came right back. After defrosting the freezer within 2 weeks little ice cycles will form under the back motor cover and under the icebox and then the crusher dispenser motor will freeze up and won’t go up and down. I thought maybe the water coming into the ice tray could be leaking but its not. Could it be that the defrost heater warms up the ice tray and the evaporator fan is not working properly to circulate the air and dry things up before they freeze up again. In about about 2 months I will take the icemaker crusher dispenser motor apart and it is a solid block of ice, where could the water be coming from that makes it all freeze up. The ice tray sits right over this but it is not leaking or is it splashing when filling. When the ice tray is full of ice cubes can the defrost comes on and make condensation under the tray and make it drip before it freezes back up. Is this a sign of a bad evaporator fan? I am now trying a ½ inch insulation board right under the ice tray to shield it from heat when the defrost is on.
Answer Hello Jay, Most of the time, a condensation issue is directly related to a door strike and door seal issue causing an air leak. In cases that this isn't the cause, the contacts for the mold heater in the ice maker can be sticking. If there are any voids in the enamel on the ice maker, the ice maker can be leaking from the chipped enamel where the mold heater is crimped into the base of the ice maker. There is also the possibility that the ice maker water inlet valve might be in the early stages of failure and only sticks open once in a while or during periods of lower water pressure such as times when the washer or dishwasher is filling, or if the shower is running. The last thing I can think of to check is whether the ice maker water supply is hooked to the cold water or the hot water. If it is hooked to the hot water, the issue could be evaporation from the water fill, especially if the freezer temperature is below the recommended 0°F. Read More...
