Error Codes

E0 iQ controller comms lost High On Modernist series ranges with the iQ controller, the oven and cooktop sections stop sharing status information. One section may show idle while the other is active. View -> E1 Control power supply fault High The control display brightness fluctuates or the display cycles through startup screens just before settling on E1 — a direct indicator that the board is not receiving stable regulated voltage. View -> E2 Sensor circuit out of range Medium An independent oven thermometer confirms the actual cavity temperature swings more than 50°F above or below the set temperature on a consistent basis. View -> E3 Gas valve ignition fault High The Heritage series oven attempts ignition several times — you can hear repeated clicking and smell brief gas — but the burner never sustains a flame and E3 appears. View -> E4 Gas pressure sensor fault High The oven does not heat on bake or broil — the igniter may click but the burner never lights, and E4 is displayed indicating a gas supply or pressure monitoring fault. View -> F1 Oven temp sensor open High The oven shuts off during bake or roast and will not resume heating. The cavity temperature drops steadily after the fault triggers. View -> F2 Oven over-temperature High Items in the oven are burnt or charred because the cavity exceeded the programmed temperature by a significant margin before the safety cutoff engaged. View -> F3 Oven temp sensor shorted High Selecting bake, broil, convection, or any cooking mode immediately triggers F3 with no heating activity. The unit is completely locked out. View -> F4 Broil burner circuit fault Medium Selecting broil mode produces clicking from the igniter but the broil burner never lights. After several failed attempts, the board displays F4. View -> F5 Door lock motor fault Medium Pressing self-clean causes the lock motor to buzz or click but the latch does not engage. The cycle will not start and F5 appears on the display. View -> F6 Control board comms fault High The bake or broil mode works but the other does not, or convection fan runs but heating does not activate. The board that lost communication controls the non-working function. View -> F7 Stuck key or touchpad fault Medium The oven starts, stops, or changes modes without user input as if someone is pressing buttons on the touchpad. Settings change randomly. View -> F8 Bake burner circuit fault High Selecting bake mode produces igniter clicking but the bake burner never lights. The oven cavity remains cold and F8 appears after the ignition timeout. View -> F9 Oven thermal runaway High A pronounced burning or scorching smell comes from the oven during a standard bake or roast cycle at normal temperature settings — well before the oven should reach any dangerous temperature. View -> F10 Control board internal fault High No cooking mode starts, no temperature responds, and no function other than the clock or display backlight may be active — the control board is alive enough to show F10 but nothing else. View -> F11 Igniter module comm fault Medium Turning any surface burner knob to the ignite position produces no clicking sound and no spark — the igniter module is offline and not responding to ignition commands. View -> F12 Control board memory fault High Clock time, oven temperature offset, timer preferences, and any custom settings stored in the board are gone after each power cycle — the board cannot write to its memory. View -> LOC Control panel locked Low The control display shows LOC or a padlock symbol and no oven function, timer, or temperature entry responds to button presses — the entire oven control is locked out.
