There are lots of adjustments on the drawer of the fridge, slide door open, behind the silver plates at bottom just like a cupboard drawer, this adjustment affects height left/right independently, there the two catches to lock the drawer in place, top and bottom in the centre. The lower one takes the weight of the door.
The white front of the door comes of easily, there are many points to lubricate and cables can be tightened to lessen the hand movement required.
If we run our fridge on three it's too cold. Two seems just right, sometimes we put it up to three a few hours before sleeping and then put it in night mode, I don't hear it come on much.
For us the fridge works brilliantly, so much so that we now take a lot more frozen food. I have two specific thermometers and check temps which are always spot on.
