Through trial and error, I figured out how to fix or repair or bypass the Ice Full issue on an Igloo portable ice maker. This seems to be a common problem regardless of name brand. I figured out how to bypass the sensor or eye to make the machine think the beam was always clear. Hopefully this works for you as well.
