 Igloo ice maker icefull light stays on

If the igloo ice maker icefull light stays on, that means 

The hard water had covered the infrared source and/or receiver. They are opposing black and transparent 3mm circles on the left and right wall when you look inside your icemaker. They are supposed to detect if ice cubes pile up so high that they disrupt the direct liner of view between those 2 dots.

Just clean them with a wet acidic solution to clean of the hardness, e.g. use vinegar or lemon juice.This process will help to get icefull light off.

Also you can try this simple trick if the above process is not helping

1. turn machine on . 2. press the select button for 10 sec. then 3. press the power button for 10 sec. and then turn off the machine and unplug it for 6 hours.

I included some links for your convenience. Good Luck
