The RB 1400 is the built-in column version of the same 2004-documented R1400 family — same electronic control and error-code display, but designed to sit inside a cabinet cutout instead of standing freestanding. That changes what we check first on a service call.
A built-in cabinet from this era depends on the original installer having left enough clearance behind the unit; two decades on, insulation, shelving, or a remodel sometimes closed that gap, and restricted airflow puts extra strain on the compressor before any part actually fails.
Key Features
- Built-in all-refrigerator column

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
DEMO mode left switched on from setup or a showroom display, leaving the panel lit with no active cooling
Ventilation clearance behind the built-in cabinet restricting airflow and straining the compressor over the long run
