The evaporator fan would make a very high-pitched whine/squealing noise usually after starting up after a defrost cycle, although, it would make the same noises during normal operation. After performing a thorough inspection of the fan blade and motor, I discovered that there was no interference to the rotating fan, and realized the motor must be failing. After removing the food and racks from the main body of the freezer, I had to remove 8 Philips-tipped screws that held the inside back panel cover on. I disconnected the fan motor from the main wiring harness, removed the fan mounting bracket (2 5/16" hex head screws), and then removed the fan motor from the mounting bracket (2 5/16" hex head bolts. I removed the fan blade and conducted a visual inspection, and found not blemishes of broken/damaged pieces. I mounted the new motor and used the existing fan blade, and replaced everything in the reverse order. I turned on the freezer and it has been operating perfectly since. I disassembled the old motor and discovered that the stator coils were worn, and the bearings allowed to much forward/aft motion.
