Hooked up waterline to side by side frigiedaire,
Your inlet tube that goes to the icemaker may be frozen.
To Check: Shut off water supply to Fridge, disconnect the water line that goes to the icemaker at top back.
Use a flexible item to insert in the water line connection.
I used a zip tie. If the flexible item won't all the through
to the ice maker, the line is frozen. Thaw out the tube
from inside the freezer with a hair dryer. Re-connect
everything, you now have ice . . .
Solution #2: You may have to replace your "Water Inlet
Valve" located at bottom right rear of Fridge.
Easy to do, just follow the color codes, be sure and shut
off the water.
