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 doesn’t change which part is actually responsible for each one.
