On the covered Thermador Masterpiece wall oven, E014 means an On/Off key that is not responding. First, cut power, dry the glass panel and then touch the middle of the On/Off key with the flat of a finger. Then: if the key stays dead, inspect the harness between the user interface and the control board for damage, replace the harness if it is damaged, then the user interface, and finally the control board.

- That the code is E014 and what the oven was doing
- Whether the other keys respond
- Whether the panel was wet or cleaned recently
- The model number from the oven frame

ReversibleCut power, dry the glass panel and then touch the middle of the On/Off key with the flat of a finger.
Correct only the documented fault domain
ReversibleIf the key stays dead, inspect the harness between the user interface and the control board for damage, replace the harness if it is damaged, then the user interface, and finally the control board.
Cut power at the breaker
ReversibleA wall oven is hard-wired, so switch it off at its breaker and leave it off for a few minutes so that the control resets.
Dry the glass panel
ReversibleWipe the touch panel with a clean, dry, soft cloth, and make sure there is no film of cleaner or grease on the On/Off key.
Restore power and press the key
ReversibleTouch the middle of the On/Off key with the flat of a clean finger, since the edge of the key is less sensitive.
Try the other keys
ReversibleIf other keys respond but On/Off does not, the fault is local to that key or its connection.
Inspect the harness
ReversibleIf the key stays dead, the table says to inspect the harness between the user interface and the control board for damage, and replace the harness if it is damaged.
Replace the user interface, then the control board
ReversibleWith a sound harness, replace the user interface, and if the key is still dead, finally the control board.
