How To advance a refrigerators Ice maker, on Whirlpool made Ice makers this is a simple process. This test will confirm either a failed water valve or Ice Maker.
Also note if you make this test and no water makes it to the Ice maker the fill tube could be frozen, this is the plastic tube that penetrates from the back, often this will become frozen with ice preventing water from making it to the tray.
This is what the front of the ice maker will look like once the plastic front is removed.
You will need a insulated jumper to make this test, also basic electrical knowledge is necessary. By inserting the jumper wire into L and V will short the Ice maker motor and send voltage to the refrigerator water valve.
If you have water upon jumping L to V the Ice maker is at fault, if no water makes it up the fill tube check the fill tube for ice mentioned above, the fill tube can become frozen. If the fill tube is clear and proper voltage is present at the refrigerator’s water valve the valve will need to be replaced in order to make ice again.
