Small part that fell, can’t tell where it belongs

[SystemEngineer]

Hi,
I have liebherr freezer model 9989338-09 (GN 2723)

I took apart the evaporator assembly and this part fell when I removed the fan

Can you tell me where it belongs?
I can’t find it on the schematic

It belongs on the fan blade, it looks out of shape and needs to be made a bit rounder to fit tight on the end of the plastic fan blade, the centre little bar prevents you pushing the blade on too far and acts as a stop position.

Thank you Tony,
The fan blade is installed in the rear with motor in front of it, I can’t insert it from the front. Do I need to take apart the back panel of the freezer? I can’t pull out the evaporator assembly.

You are going to have to push off the fan blade and remove it (not a lot of room and you will need to be on a small set of steps ) you can with a bit of fiddling around extract the blade once pushed off the spindle of the motor and fit the clip, however I do not see a problem leaving that clip off, providing the blade is a tight fit on the motor shaft and spins freely without jamming on anything.

I understand that it prevents pushing the fan on the motor axis, but it doesn’t prevent it slipping off. It fell off when I removed the fan to test it. When I put the fan back the first time, it was too close on the shaft and made some noise upon opening the door. I moved it a little back and it is silent now. I think that I’ll leave it off for now.
By the way, the freezer was too hot and I thought that something was wrong in the evaporator, but the issue was that the door magnet wasn’t in place and the fan didn’t spin. I took apart half of the freezer because of that small problem, felt like a total idiot when I realized it.
