Where the HC2092G uses a glass door, the CS2091G is Liebherr’s solid-door combination refrigerator-freezer with the same BioFresh drawer and the same split control setup — plus frost-free operation on both halves, which adds a defrost heater and timer to the parts that can fail.
Most of what goes wrong here is either that defrost hardware or a drift in the BioFresh drawer’s own sensor reading; the frost-free system is the one meaningful difference in what we check versus an older manual-defrost Liebherr combo.
