The GRT21S1HC is a solid stainless reach-in refrigerator built for continuous food-service use, running the same F-series electronic control platform Liebherr uses across its residential line.
A specific F-prefixed code, door seal wear from the high door-opening frequency a working kitchen puts on it, and uneven cooling when condenser airflow gets restricted by tight kitchen placement are the three things checked on this model.
Key Features
