The CUN 3033 Comfort NoFrost is a built-in, undercounter combination refrigerator-freezer with automatic-defrost NoFrost — fitted beneath a countertop rather than standing as a full-height cabinet, on Comfort-tier control.
A specific F-prefixed code and a NoFrost cycle not clearing frost on schedule are the two complaints specific to the electronics; because it’s undercounter, the cutout also gets checked for enough airflow beneath the counter for the compressor.

Most Common Issues on This Model
Control panel showing an F-series error code — Liebherr documents the problem ranges but reserves the specific-digit meaning for a technician's own service lookup, so we read the exact code before opening anything
NoFrost defrost cycle not clearing on schedule, leaving frost building up on interior surfaces
Ventilation clearance beneath the counter restricting airflow and straining the compressor over the long run
