Evaporator Fan Squeeking

found this instruction helpful.
Detected noise as coming from top freezer department, and tips and part diagram clearly pointed to evaporator fan. You go in through the freezer (you have to empty top half of freezer); removing the side rails holding the ice bin, and then the 4 outer screws (only 2 each side - not the middle ones) holding the 'auger' that turns the bin

. From there it gets interesting in trying to disconnect the wires. You might consider taking some pictures of the connected wires - perhaps it doesn't matter, but several of them can be hooked up in reverse. After the ice marker is out, remove light and light cover, side rails/mounts that hold hold up ice maker. This leaves a large white cover that pops out (seam at bottom of it has two tabs that you can pop out) holding the fan; and then only a few more wires to disconnect to be able to get at the fan. Mine clearly had a wobble to it confirming the source of the squeak and need to replace. Install was just reverse -- a bit tricky to get some of the wires connected given the tight spaces. Overall, not difficult - but a lot of wires and screws to connect/disconnect. I didn't take any pictures as I disassembled, and found myself having to take some extra time to figure it out as I reassembled. In the end -- a silent and functioning refrigerator Good luck!
