What L
actually means.
L tells you the locking function has been switched on, so the zones will not respond to the knobs. It is a deliberate setting for safety, not a message about a failed part.
La Cornue range display
What to do when L shows on the rangeKind of codeMode, not a failure
Something the range was told to do, or a state it chose on purpose — a control lock, a Sabbath setting, a demo mode that lights the display but never heats, a pan warning on an induction zone. Nothing has worn out, and no part is needed.
Usually leads toNo repair
Switch the locking function off as described in your Château guide, then set the zone again.
Shows up asRange Control Panel Not Responding
The touch keys or knobs on the range do nothing, only some keys work, the display is blank or frozen, or it beeps without starting.

Before you book,
in this order.
Each step comes from La Cornue's own guidance for L on its ranges. Follow it to the end: the last card says whether this is a visit.
Switch the locking function off as described in your Château guide, then set the zone again.
Cleared?
The range was set right without a new part. If the same message comes back while a burner or the oven is in use, or the range cuts out again, treat it as a new problem and book it.
What not to do
An L display does not mean the controls have failed; the plate is simply locked.

Gas range
Open flames on top and a gas-fired oven below, all fed by one supply line behind the range and lit by igniters rather than a match.
Dual-fuel range
Gas burners on top and an electric oven below, the combination most professional-style ranges use, needing both a gas line and a 240-volt circuit.
Induction range
A glass top that heats the pan itself through copper coils and power boards, over an electric oven, with electronics doing almost all the work.
