Thermador Oven Error Code E10

E10 on a Thermador oven indicates a problem with the control board, specifically the earlier Dreefs control system used in certain models. The error locks the COOK MODE window display and makes the oven completely inoperable. This is an internal board-level fault that cannot be cleared through normal reset procedures. The control board must be replaced to resolve the issue.

No. The E10 error is a persistent fault that remains in the COOK MODE window and renders the oven unusable regardless of power cycling or reset attempts. Because the fault originates within the control board itself, disconnecting power and reconnecting it will not clear the error. Board replacement is the required corrective action.

Repair costs for an E10 error will vary depending on the specific Thermador model and the cost of the replacement Dreefs control board. Parts alone typically range from $150 to $400 or more for control boards, and professional labor can add another $100 to $250 depending on your location and service provider. Getting a quote from a certified Thermador service technician before proceeding is recommended.

Replacing the control board is a task that some experienced DIYers can perform, but it requires comfort working with appliance wiring and electronic components. The board must be the correct replacement for your specific Thermador model and control variant. If you are not confident working inside the oven's electrical components, a qualified appliance technician should handle the replacement.

The oven is completely inoperable when E10 is displayed, so there is no active cooking function to create an immediate hazard. However, you should not attempt to force the oven into operation or bypass the error. Leave the oven unused until the control board has been properly replaced by a qualified technician.
