Thermador Oven: error code e6104
What is this symptom?
If your Thermador oven or range displays error code E6104, this indicates a potential malfunction in the control or sensing systems. You may experience the oven shutting off unexpectedly or the internal cooling fan running continuously. This error code is not documented in official listings, suggesting that model-specific diagnostics may be necessary.
Important Tips for Thermador Models
- Thermador’s official documentation does not list E6104 in publicly available error code lists, and directs users to contact customer support for unknown error codes.
Possible Causes
Control board malfunction
How to Identify: Error code appears persistently even after resets; random shutdowns during operation; symptoms may include inability to maintain heat cycles.
Part: Electronic control board / main control module
Temperature sensor failure or open/shorted sensor circuit
How to Identify: Error appears during or after heating cycles; continuous cooling fan operation may indicate the oven thinks it is overheating or sensor is missing correct readings.
Part: Oven temperature sensor (RTD)
DIY Solutions
Hard reset the oven/range
- Turn all oven/range controls to OFF.
- Switch off the circuit breaker feeding the oven/range or unplug the unit from its power source.
- Leave without power for at least 5–10 minutes to allow control systems to discharge and reset.
- Restore power and check if the error recurs during normal operation.
