The high pitched wine from the evaporator fan can either be the fan bearing or ice build up. If your not noticing the freezer temps warm up I would suspect the fan bearings. If you notice things like soft ice cream then you may have an automatic defrost problem. To isolate the possibilty of an automatic defrosting problem and post procedure fan test perform the following manual defrosting steps:
1. Unit unplugged
2. Remove freezer contents
3. Place a fan blowing into the freezer compartment for 2 hours
(Messy - rags and mop required)
4. Wipe residual water in freezer compartment
5. Plug in unit
6. Reload freezer contents
Check for fan whine and normal temps in 4 hours.
If the fan is no longer whining you probably have an automatic defrosting problem. If it still whines you can try lubricating the fan motor bearings with "Zoom Spout" oiler (Any Appliance parts source carrys this for under $3.00) Do not use regular oil!
It will cause the fan motor to sieze in about 1 month.
Worst case the evaporator fan motor would have to be changed:
