LSC27921SB03 LG Refrigerator - Overview

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!

To replace the warped tray, I found the service manual (pg. 124 below) which took some interpreting.
Removed the lever. Then removed the assembly by two screws that are forward to the unit and go upwards.
The insulation, sensor, and sensor cover are simply pulled down and off and the unit separated to removed the tray, and then insert the new tray. Proceed in reverse. Takes only a few minutes.

This site was awesome! I was able to very quickly look up my refrigerator model, find the proper part number, and order the part. The only suggestion I would make is to update the cut sheet with a more clear version, it was a little difficult to make out the part number because the scan/drawing was fuzzy, but I was still able to make it out. Got the part in the mail very quickly and it was super easy to remove the old rail and install the new one. Take out the screws from the old one, remove the old rail, line up the holes, install the new one, and put back the screws. It's so nice to have a site like this to fine parts and order them! Too cool! Thank you so much!
