Two things make a La Cornue call different from a routine range call. The first is that the appliance is often built into cabinetry and stonework that was designed around it, so pulling the range forward is itself part of the job and has to be planned rather than improvised. The second is that parts are model-specific and frequently ordered from France — which is why the diagnosis has to be right the first time, and why a technician who guesses costs you weeks, not just a return visit.
If you can smell gas near the range, shut the gas off at the appliance valve before doing anything else, leave the burners alone, ventilate the room and call from outside it. Everything else — a burner that will not light, an oven that runs cool, a door that no longer seals — is a booking, not an emergency.
Common Range Problems
Oven will not reach or hold the temperature the dial is set to
Burner clicks or sparks but never lights
Smell of gas around the range
Oven door sags, will not close flush, or the seal has hardened
Thermostat reads correctly at one temperature and drifts at another
Brass or chrome trim loose, or a control knob turning without engaging
