The conversion compartment is a part that can be switched between different settings based on your need. If you need more freezer space, you can change it to a freezer. If you need more refrigerator space, flip the switch to refrigerate. It can be pretty useful as you can change the space set aside to different things pretty much on a whim.

I am going to second the opinion that the error is probably the reason why things aren't getting cold, and not your settings.
