had this to say:

As this is uk.d-i-y I feel compelled to point out that if the cooling plate
is cold but the fridge stays warm it's probably just the door seal not
sealing properly. Either the door is twisted (just apply twisting force to
repair) or the seal is simply knackered (buy a new one and fit). No way to
fix it with an angle grinder that I know of.

You could spray it with WD-40 though.

Or use car body filler.
