Older models of Whirlpool/Kitchen Aid/Jenn Air have a set of jumpers on the control board. You change the jumper setting and the ice thickness will change. I now have a newer version of the ice maker (Jenn Air Model JIM158XWRS0) that has a new control board that does not have the jumper settings to control ice thickness.
Most of the literature I can find for repair tells me the resistance readings for different components based on ice thickness which implies that there is a way to change the ice thickness, I just can't figure out how to do it. The control panel has four buttons, no way to control it there either. Any ideas?
