The CBP 4043 Comfort BioFresh pairs a BioFresh drawer with a freestanding combination refrigerator-freezer cabinet, on Comfort-tier control, without the added NoFrost defrost system. A specific F-prefixed code and a BioFresh drawer that won’t settle into its near-0°C range are the two things that bring most owners of this model to call.

The CUN 3523 Comfort NoFrost is another undercounter, built-in combination refrigerator-freezer with automatic-defrost NoFrost, same Comfort-tier control as the smaller CUN models. A door-closed alert misfiring and the automatic defrost cycle slipping out of schedule are the two electronics complaints on this unit; because it sits in a counter cutout, clearance for airflow underneath still […]

The CBPesf 4033 Comfort BioFresh is a slightly smaller cabinet than the CBP 4043 but shares the same BioFresh-equipped combination format and Comfort-tier control. A demo setting left active from setup and a BioFresh drawer that won’t hold its target range are the two complaints specific to this model.

The CUN 3923 Comfort NoFrost is a larger undercounter combination cabinet than the CUN 3523, same automatic-defrost NoFrost system and Comfort-tier control. A dashed readout instead of a number, and frost creeping back despite the automatic cycle, are the two things owners of this size cabinet call about most, alongside the standard beneath-counter airflow check.

The CBPesf 4043 Comfort BioFresh matches the CBP 4043 in cabinet size and BioFresh format, under its own model designation. A door alert sounding with the door shut and a BioFresh drawer refusing to settle into range are the two complaints we see most on this model.

The CUN 4023 Comfort NoFrost is the largest of the CUN-series undercounter combination cabinets in this group, same NoFrost system and Comfort-tier control as its smaller siblings. A logged power interruption on the display and the defrost cycle falling behind schedule are the two complaints specific to this model, on top of the routine airflow […]

The CBNPes 3756 Premium BioFresh NoFrost combines BioFresh and automatic-defrost NoFrost on one freestanding combination cabinet, running Liebherr’s Premium-tier control — more systems on one unit than the plain Comfort-tier combination models. A specific F-prefixed code, a BioFresh drawer out of range, and a NoFrost cycle falling behind schedule are the three things isolated on […]

The CUNesf 3523 Comfort NoFrost matches the CUN 3523 in cabinet size and NoFrost format, under its own model designation. Whichever F-number is actually lit on the panel, and the defrost cycle slipping out of schedule, are the two things checked first on this unit, along with the same under-counter clearance inspection as any CUN-family […]

The CBNPes 3967 PremiumPlus BioFresh NoFrost is a larger version of the CBNPes 3756, same BioFresh-and-NoFrost combination format, stepped up to Liebherr’s PremiumPlus control tier. A demo setting left active, a BioFresh drawer out of range, and a NoFrost cycle not clearing frost are the three complaints specific to this model — the larger cabinet […]

The CUNesf 3923 Comfort NoFrost matches the CUN 3923 in cabinet size and automatic-defrost NoFrost system, another undercounter combination unit under its own designation. A lingering demo toggle keeping the panel lit without cooling, and frost building up despite the automatic cycle, are the two complaints specific to this model.
