I'm not sure about the Liebherr origin, there was a Liebherr next to this one and they were quite different from eachother. The drawers indeed all have the same temperature.
The 90, 180, 360, 600 and 800 are the settings in Watts for the microwave. There is no turning table, just a turning antenna at the centre of the top of the oven. Besides from a microwave and a convection oven it also has a broiler and a conventional heating system. I love it!
The old fridge had a big bubble on the back, apparently it had swollen up, somehow water must have gotten into the insulation.
The burners on the classic cooktop were difficult to regulate. Six years ago I came across this ATAG cooktop in a thriftstore. It was only 15 Euros (around $20.-). It works great, but the stainless steel is hard to clean.
