Ice maker isn't making ice... I noticed a few weeks ago that our ice maker wasn't producing much

Question

I noticed a few weeks ago that our ice maker wasn't producing much ice. When I tried to get ice a few days ago, I noticed there were only like 3 pieces of ice in the compartment. I checked to make sure it was switched on and the little overflow flap was down and it is. Does anyone know why it's not producing ice?

maytag 2 door first producing to much ice then since emptying manually no ice production checked water flow slow put up temperature water filter light on green but ok and change light not showing cut of leaver is down
