B — Common issues
What we fix on La Cornue cooktops.
/01
Single burner won't light
One gas zone fails while the rest spark normally. Clogged ports or orifice on that burner, a cracked electrode, or a misaligned burner cap breaking the spark gap.
/02
No burners spark
No zone produces a spark on ignition. A failed ignition module, a tripped spark switch, or a wiring fault feeding the electrode harness.
/03
Continuous clicking
The igniter clicks without stopping, even with knobs off. Moisture in an electrode, a cracked electrode boot, or a stuck spark switch shorting the module.
/04
Low or uneven flame
Flame is small or irregular at a steady setting. A partially clogged orifice or ports, low supply pressure, or an air-shutter set incorrectly for the fuel.
/05
Induction "U" pan-detect fault
A single induction zone flashes "U", meaning no pan or an incompatible pan is detected. If other zones work with the same pan, the zone coil or pan-detector sensor is at fault.
/06
Induction cut-out E2
Induction shows code E2 — the electronic unit is too hot or a pot has boiled dry. Check ventilation clearances; persistent E2 indicates a cooling-fan or sensor fault.
/07
U400 wiring fault
Induction displays U400 and shuts off after about one second, with the code remaining: the cooker is incorrectly connected. The supply wiring and connection must be corrected.
/08
Cracked induction glass
The ceramic-glass induction surface is cracked from impact or thermal stress. The glass top is replaced as an assembly; a cracked surface must not be used.
/09
French-top plate cracked or warped
The cast-iron French top (plaque coup de feu) cracks, warps, or rusts. Caused by thermal shock, standing water, or a lapsed seasoning routine; severe cases require plate replacement.
/10
Burner cap or grate corrosion
Brass burner caps or cast grates corrode or discolor. Aggressive cleaners, standing moisture, and missed maintenance; restored with correct care or replaced when pitted.
/11
Stiff burner knob
A gas valve knob is hard to turn or binds. Hardened grease in the valve, a dry valve stem, or a worn knob bezel rubbing the panel.
/12
Teppanyaki not heating
The electric teppanyaki module fails to reach temperature. A burned-out element, a failed thermostat, or a control connection fault on the module.
These are the most common issues — not an exhaustive list. Our technicians diagnose and repair any La Cornue cooktop problem, including intermittent faults, unusual symptoms, and issues not listed here.
