Whirlpool GS6SHAXMQ Side by Side Refrigerator - Ice Maker Problem
This happened to me after i had to move the freezer and it was unplugged for a while. When it was plugged back in the ice maker would not work.
Assuming both the ice maker itself and the rear water AC solenoid switch are actually not broken and are functional, and you are getting water from front door dispenser, then check the inside supply tube (black) is not frozen and blocked. Check with q-tip or feel to see if frozen.
If supply tube is frozen, thaw by holding up small full clear glass of heated water placing the frozen tube into the heated water. The clear glass will allow you to see when ice slips out.
Next try resetting the freeze cycle. Turn off the ice maker switch, remove the maker by carefully disconnecting the inside power cord. You will need to remove the inside door flap. Rinse the maker with warm water, allow to come to room temp.
Re-install maker, connect power cord. Turn on ice maker switch. Make sure Infrared sensor is not blocked. Now wait for temp change and listen for water to fill tray. It took maybe ten minutes for me. You will be able to hear the water fill with the door closed.
Again, this assumes nothing is actually broken.
This worked for me. Good luck.
