Model overview
Owners who buy a 47-inch range such as the Château 120 range usually cook often and host regularly, so the appliance gets daily use from the burners and the oven at once. That steady workload explains why a sluggish oven or a stubborn knob gets noticed quickly in a busy household. This La Cornue model sees a lot of cooking, and small faults can build up over months when nobody writes them down. Note which burners clicked or failed to light, whether the oven runs hot or cool, and whether a knob sticks. Technicians in Los Angeles and Orange County find those details far more useful than a general description. For the booking form, give the model name, the most frequent symptom, and any code shown on the panel.
Château 120 range is a La Cornue 47 1/4" range. The model number is printed on the rating label, usually on the frame behind the storage or warming drawer, or around the oven door opening; match it letter for letter before booking, because a single letter can change parts.
