La Cornue Range
Error Codes

E0 Board Communication Error Medium Parts of the digital display are blank, show incorrect data, or the display works intermittently. View -> E0 Control Board Comm Error Medium The digital display shows incomplete information, is partially lit, or goes completely blank despite the range having power. View -> E1 Gas Valve Relay Failure High The oven igniter glows but gas never flows to the burner because the relay won't energize the gas valve. View -> E1 Control Board Self-Test Fail High The range shows no response to any control inputs after being powered on — no heating, no display activity, and no acknowledgment of button presses. View -> E1 Gas Pressure Fault High All gas burners produce unusually small, weak flames that cannot reach full heat output even at maximum settings. View -> E2 Convection Fan Motor Fault Low Food cooks unevenly with hot spots and cold spots, or one side of dishes browns significantly more than the other. View -> E2 Heating Element Circuit Fault High The control panel shows the oven as active and counting up toward the set temperature, but no heat is produced and the cavity remains at ambient temperature. View -> E3 Cooling Fan Failure Medium The area around the control knobs and digital display feels abnormally hot during or after oven use. View -> E4 Flame Supervision Failure High The oven burner ignites and produces a flame, but it extinguishes after 10-30 seconds as the flame sensor fails to confirm stable combustion. View -> E5 Gas Leak Detection Alert High A distinctive rotten-egg gas smell is noticeable near the range even when all burners and the oven are turned off. View -> E6 Bake Element Open Circuit Medium Food placed in the oven cooks unevenly or not at all — the top of the oven may warm from convection or the broil element, but the bake element produces no heat. View -> E7 Broil Element Open Circuit Medium Foods placed under the broiler receive no direct heat from above — browning and searing do not occur even after extended time under what should be an energized broil element. View -> F1 Oven Temp Sensor Open Medium The oven cavity remains cold after setting a temperature and pressing start, with no warmth detected even after 10+ minutes. View -> F1 Oven Temp Sensor Open Medium The oven cavity remains cold after a temperature is set and start is pressed — no warmth is detected even after 10 or more minutes of operation. View -> F1 Oven Igniter Failure High The oven remains cold despite selecting a temperature and starting the cooking cycle, with no visible flame in the oven cavity. View -> F2 Oven Temp Sensor Short Medium The oven begins its preheat cycle but shuts down within seconds, displaying the F2 code. View -> F2 Oven Temp Sensor Fault Medium Food burns on one cycle and comes out undercooked on the next, even at the same temperature setting. View -> F3 Oven Overtemperature High The outside surfaces of the range, including handles and surrounding cabinetry, feel unusually hot. View -> F3 Oven Overtemperature High The oven heats well past the programmed temperature before the error triggers, often scorching food or setting off smoke alarms. View -> F3 Oven Overtemperature High The outer surfaces of the range become dangerously hot, potentially causing burns on contact and heating nearby surfaces. View -> F4 Sensor Out of Range Medium Recipes that previously cooked correctly now produce inconsistent results despite using the same temperature settings. View -> F4 Oven Temp Sensor Short Medium The oven begins its preheat sequence but stops within seconds as the control board reads an implausibly high temperature and triggers the fault. View -> F5 Control Board Failure High Pressing any buttons or turning knobs produces no response — the range appears dead despite having power. View -> F5 Control Board Comm Error High Buttons and touch inputs on the control panel do not register, or the range does not respond to any commands entered by the user. View -> F5 Gas Safety Valve Failure High The igniter reaches full temperature (bright orange glow) but the oven burner never lights because gas cannot pass through the valve. View -> F6 Thermostat Malfunction Medium Food burns at low temperature settings or remains raw at high settings, indicating the thermostat is not regulating properly. View -> F7 Door Lock Fault Medium When starting a self-clean cycle, the oven fails to engage the door lock and displays the F7 error instead of proceeding. View -> F7 Door Lock Motor Failure Medium When a self-cleaning cycle is initiated, the door lock motor activates but the door remains unlocked, preventing the cycle from starting. View -> F8 Oven Igniter Failure High You may notice a brief gas odor when the oven attempts to light, followed by the F8 error as the safety valve closes. View -> F8 Burner Ignition Failure Medium The spark igniter clicks continuously but the burner does not light, despite gas being available. View -> F9 Door Latch Circuit Fault Medium The oven behaves as if the door is open when it is clearly shut, refusing to start or maintain heating cycles. View ->
