I was an appliance parts distributor. refrigerator ice-makers for your model are available inexpensive. 4317943 or D7824706Q, less than $50.00. I keep a spare. It’s either the water fill valve or ice-maker defective. Ice-makers fail much more often.
You can remove front cover of ice-maker. And you will see holes. The holes allow you to test icemaker and water valve. Insert jumpers between holes to activate water valves, harvest ice, turn ice-maker mold heater on.Do a search to find procedure.
