My ice maker runs water in to bin. Still makes ice but now all is frozen in the bin. Is it the water valve?
Normally the water valve would not cause this type of issue unless it is continuously streaming. You will want to check to make sure that the fill cup is not freezing over and pull the icemaker out to make sure that the mold is not deteriorating. The deterioration of the coating on the mold is most likely the cause. When the mold deteriorates the water will drip out onto the ice that is in the bin. If the water seems to be dripping towards the back of the bin then the fill cup may have ice in it. If you clear the ice and the issue continues to occur then replace the water valve.
