Hello, I can help you with this. The first thing to do is open the freezer drawer and look up to see if there is a bunch of frost on the roof of the freezer.
It is possible that the unit has a problem with the defrost and can be fixed by you. Regardless I can help you determine the problem and estamated repair cost.
The second thing to do is hold down the ice on/off button for 15 seconds and see if you hear a crackling sound from the freezer.
