Hi and welcome to FixYa, I am Kelly
First off check the freezer door switch for operation. Depress the plunger and make sure the light goes off when the door switch plunger is depressed. Ligt stays on = bad door switch / no ice production as the door switch provides power to the ice-maker when the door is closed.
Here is a link to the steps on how to troubleshoot an ice-maker.
Let me just add that many ice-maker related problems are due to the freezer temp rising above 16 deg F. The freezer starts warming up due to ice build up on the evaporator coils and then the internal air-flow is blocked by the ice build up causing the temps to rise. Look closely at the back of the unit for any signs of ice build up.
If you see ice build up......
1. Unplug the unit
2. Remove the freezer contents
3. Place a fan directing air into the freezer for just over 2 hours. (Water mess!)
4. Clean up the excess water and restart the unit. (Add freezer content)
5. After 8 - 10 hours check for ice production.
If after doing the above you have ice production then most likely you have an automatic defrosting problem.
If it still does not make ice, the steps in the link above will isolate what has failed in the ice-maker.
Before testing the ice-maker using the steps in the link.. I recommend you peform a manual defrost with a fan. If 8 - 10 hours after the manual defrrost you do not have ice production,, use the link and troubleshoot the ice maker.
