Ok Bart, sounds to me like you have 2 problems here not one. The first problem sounds like a blocked defrost drain , this is why you have a ice sheet on the lower shelf. Follow the instructions below to clear this problem.
In order to fix this problem remove the shelfs/drawer from the freezer, Next remove the lower panel in the rear. Behind this panel you will see the evaporator (looks like a car radiator) below this you will see the defrost drain pan.
Use a hair dryer to melt the ice you will see in the drain pan. Mop the water up you will then see the defrost drain. Pour hot water into the drain pan, leave the water for a few minutes then mop it up, Repeat this several times until you see the water drain away.
At this point you will be all set and can button the unit back up :)
The problem with the grinding ice maker
is because the heater inside the mold where the ice is made has failed, this is causing the motor to strain (noise) the small ice cubes are further evidence that is the problem. In this case the ice maker will eventually fail so it will need to be replaced.Click here to order a new ice maker
