Also, the ice maker works intermittently. It will stop working for days-to-weeks at a time and then begin working normally again. Since the water arriving at the fridge is already filtered and softened we do not use a filter in the fridge. Our filtration is charcoal-based. Our softener adds potassium chloride. I wonder if the paper-like sheets that are getting stuck to the ice are (a) causing the intermittent functioning and (b) caused by the potassium salts in the water. Have you seen or heard of anything like this? What would you try to resolve this? I have ordered water filters for the fridge and will find out if they resolve the issue. If they do I will assume it's the potassium chloride causing these weird paper-like sheets. I have images but see no way to attach them.
