What Does Error E012 Mean?
The Thermador oven error E012 indicates a malfunction in the temperature sensor or control electronics, leading to erratic temperature readings or the oven failing to heat properly. This may also cause the oven to stop cooking cycles and emit beeping sounds.
Common Symptoms:
- Error code E012 displayed on oven control panel
- Oven may stop heating or refuse to start cooking cycles
- Possible beeping accompanying the error
Possible Causes
- Defective electronic control board temperature sensor (medium)
How to Fix Error E012
DIY Fix Basic checks and reset
- Press any key (e.g., TIMERS) to stop beeping if present.
- Turn off power to the oven at the circuit breaker or unplug for at least 60 seconds, then restore power.
- Observe if E012 recurs when attempting normal operation.
Technician Only Inspect and replace the temperature sensor or control board
- Disconnect power to the oven.
- Access the oven’s internal control electronics and temperature sensor components.
- Use a multimeter to test the temperature sensor for proper resistance at room temperature.
- If the sensor is out of specification, replace the temperature sensor.
- If sensor tests good but error persists, test/inspect the control board for faults and replace as needed.
Parts needed: Temperature sensor/thermistor, Electronic control board
- If the error persists after reset and basic checks
- If testing shows sensor and control board anomalies
- If internal inspection reveals wiring damage or burnt components
