watched a recent vid by Simon - https://www.youtube.com/watch?v=BoHeI714NDE.
But this Thermador is a different SxS.
Not concerned about getting the old out, but getting the new in.

Is the door lining more or less the same on this fridge as the one in the vid above?
Does the new gasket have a hard edge that fits in the lining slot or soft?
The local appliance repair people seem to be reluctant to do the job.
