Thermador Range Error Code E:24

E:24 indicates that the motor power relay inside the main control module has failed. The control board monitors the relay responsible for delivering power to the motor circuit, and this code is triggered when that relay does not operate correctly. The appliance will typically shut down to prevent unsafe conditions. Resolving this code usually requires diagnosing or replacing the control module.

A power reset may temporarily clear the E:24 code, but if the relay has physically failed, the error will return as soon as the appliance attempts to operate the motor circuit again. Resetting does not repair the underlying hardware fault. A proper diagnostic inspection of the control board and motor circuit is necessary to resolve the issue permanently.

Repair costs vary depending on whether the issue is a wiring fault or a failed control module. A wiring repair or connector service may cost relatively little in parts, while a replacement control board can range from a few hundred dollars to over five hundred dollars for parts alone, plus labor. Getting a diagnostic evaluation from a qualified technician before purchasing parts is strongly recommended to confirm the root cause.

Diagnosing this fault requires testing the control board relay output and inspecting motor wiring, which involves working with electrical components and is best suited for experienced technicians or knowledgeable DIYers with a multimeter. If the control board relay has failed internally, the board will need to be replaced, which is a more involved repair. Basic wiring inspections and connector checks can be performed by a careful DIYer, but board replacement requires proper handling of sensitive electronics.

It is not recommended to continue operating the appliance while E:24 is active. A failed motor power relay can result in unpredictable motor behavior or a loss of control over powered components. The appliance has flagged this fault specifically to prevent unsafe operation, and using it in this state could worsen the damage or create a safety hazard.
