Low Medium High

Code Meaning Severity Common Symptom

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 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 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 a temperature is set and start is pressed — no warmth is detected even after 10 or more minutes of operation. 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 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 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 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
