Château Suprême (Grand Palais 180 body, hob codes 180 N1, N1 SPE, N2, N2 SPE, NM, NM SPE)
La Cornue Château Suprême Designer Range Repair
Most common issues on this model
- Oven, and each warming cupboard, against its set temperature
- Flame at the burners, French top, power burner and lava-rock grill, wherever the installed code includes them
- Reeded trim sitting tight on the body
- Knobs that turn without engaging the control
- Gas pressure, burner ignition and the flame-safety device on any position that lights and then drops out
The Château Suprême is a special edition of the Grand Palais 180, restyled by the interior designer Ferris Rafauli. Compared with the base range it adds a pair of warming cupboards, a walnut chopping block set into the cooktop, knobs made from two materials, fluted metal trim and an LC-FR plate that names the edition.
Like its relatives, the range is mechanical and shows no codes. We test the flame at each burner, the French top, the power burner and the lava-rock grill where present, then gas pressure and the ignition and flame-safety device. The oven and each warming cupboard are read with a thermometer against their settings.
Finish matters on an edition like this. We check that the fluted trim sits tight and that each knob grips its control. Model and serial come from the label before parts are ordered, with a written price first.

What sets the Suprême apart from a standard Grand Palais 180?
It shares the Grand Palais body but adds warming cupboards, a chopping block section, fluted trim, two-material knobs and an LC-FR plate. We service the hob and oven just as on the base range, and add the cupboards and the trim to the visit, since those are the parts that only this edition has.
A knob turns but nothing happens. What do we check?
Whether the knob is slipping on its shaft, which any loose knob can do, before testing the control behind it. We then see whether the burner or oven responds when turned by hand, and whether the two-material knob seats fully on the stem.
Do the warming cupboards need separate testing?
Yes. The cupboards heat independently of the oven, so we measure each one's temperature with a thermometer against its setting and test its own heat source and thermostat.
