Liebherr CUN 3923 Comfort NoFrost

Model # CUN 3923

Liebherr refrigerator repair

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.

Key Features

  • Built-in undercounter combination refrigerator-freezer
  • Comfort-tier electronic temperature control
  • NoFrost frost-free operation with automatic defrost cycling

Most Common Issues on This Model

01

Dashes shown instead of a temperature reading, meaning the compartment hasn't yet reached a safe range rather than a part failure

02

NoFrost defrost cycle not clearing on schedule, leaving frost building up on interior surfaces

03

Ventilation clearance beneath the counter restricting airflow and straining the compressor over the long run
