the world to hear...
I'm think of chucking my fridge-freezer and replacing it with separate
units, because of the better control that you get with a separate compressor
for the fridge. In the recent hot weather, the freezer was working fine, but
the fridge section was running at 10-12C.

Get a fridge-freezer with twin compressors.
