Thermador Oven Error E012

DIY Fix Basic checks and reset

1. Press any key (e.g., TIMERS) to stop beeping if present.
2. Turn off power to the oven at the circuit breaker or unplug for at least 60 seconds, then restore power.
3. Observe if E012 recurs when attempting normal operation.

Technician Only Inspect and replace the temperature sensor or control board

1. Disconnect power to the oven.
2. Access the oven’s internal control electronics and temperature sensor components.
3. Use a multimeter to test the temperature sensor for proper resistance at room temperature.
4. If the sensor is out of specification, replace the temperature sensor.
5. If sensor tests good but error persists, test/inspect the control board for faults and replace as needed.
