I have a 2 year old Maytag Refrigerator Freezer.
The Freezer is on the bottom.
It appears that when all the ice is gone... the freezer starts making a weird noise, sort of a rolling squeaking sound, The machine is also very slow to make ice. Any ideas?

One problem it may be is that the evaporator fan motor bearings are bad, causing the squeak and poor cooling because of improper air circulation in the freezer compartment.
