Dacor Oven
Error Codes

E1 Temperature calibration error Medium Food is reliably underdone or overcooked at the same temperature setting — a consistent 25°F or more deviation from the set point is the hallmark of E1. View -> E2 Cooling fan fault Medium The top and side panels of the wall oven feel significantly hotter than usual during and after cooking — heat that the cooling fan would normally exhaust is building up inside the chassis. View -> E3 Convection fan motor fault Medium Food browning is inconsistent across the pan — one side is done while the other is pale — because the convection fan is not circulating air across the full cavity. View -> F1 Control board failure High The oven ceases to heat during bake or broil and displays F1 on the control panel. Temperature drops rapidly. View -> F2 Oven over-temperature High Items in the oven come out burnt or charred because the cavity exceeded its programmed temperature by a significant margin. View -> F3 Temperature sensor fault High Selecting any cooking mode immediately results in F3 with no heating activity. The display shows "---" for temperature. View -> F4 Sensor out-of-range reading Medium The oven runs 25-75 degrees above or below the programmed temperature and the display shows F4 intermittently. View -> F5 Door lock assembly fault Medium The oven begins the self-clean sequence, the lock icon appears, but the cycle cancels within the first two minutes and F5 is displayed. View -> F6 Door latch switch circuit Medium Selecting self-clean causes immediate cancellation with F6 displayed — the board refuses to allow high-temperature operation without a confirmed door-lock signal. View -> F7 Stuck keypad button Medium No buttons on the oven control panel produce a response — neither beeps nor display changes occur when pressing any key. View -> F8 Door latch motor fault Medium Selecting self-clean results in F8 displayed within the first 1-2 minutes. The door lock may activate but the cycle does not proceed. View -> F9 Door not confirmed locked Medium One area of the oven cavity runs much hotter than others, causing uneven browning and charring on one side of baked items. View -> F10 Runaway temperature fault Medium Neither bake, broil, nor convection modes produce any heat. The oven accepts the command but temperature never rises. View -> F11 Board communication lost High The oven control display loses all content, shows repeating dashes, or cycles through startup screens without settling — a direct sign that the main board cannot communicate with the display module. View -> F12 Thermal cutout tripped High The oven goes completely cold — no bake element glow, no igniter activity, and no heat output of any kind. This distinguishes F12 from sensor faults where heating may be intermittent. View -> F30 Lower oven sensor fault High On Dacor double-wall ovens, the upper cavity functions normally but the lower cavity will not heat in any mode and shows F30. View -> F31 Lower oven over-temperature High The lower cavity on a Dacor double-wall oven exceeds its target temperature significantly and the control board triggers a safety shutoff. View -> LOC Control panel locked Low The control panel displays LOC or a padlock icon and no button press starts any function — the entire touchpad is locked out. View ->
