What Does Error E201 Mean?
The Thermador oven error E201 indicates a malfunction in the lower oven temperature sensor, leading to erratic temperature readings and poor cooking performance. This error occurs when the oven detects an out-of-range or missing signal from the sensor, causing the oven to fail to reach or maintain the desired temperature. Symptoms include fluctuating temperature readings and inconsistent cooking results.
Common Symptoms:
- Error E201 displays on oven control panel at startup or when heating begins
- Oven fails to reach or maintain temperature
- Temperature readings may be incorrect or fluctuate
- Cooking performance abnormally poor or inconsistent
Possible Causes
- Faulty lower oven temperature sensor (medium)
- Loose or damaged wiring/connectors on the lower oven temperature sensor circuit (medium)
- Electronic oven control board misreading sensor signal (low)
How to Fix Error E201
DIY Fix Basic Checks Before Calling Service
- Turn off and disconnect power to the oven at the breaker or plug.
- Wait a few minutes and restore power to see if the code clears.
- If comfortable and safe, visually inspect lower oven sensor wiring for obvious damage or loose connectors.
Technician Only Diagnose and Replace Faulty Sensor or Related Component
- Disconnect oven power and access the lower oven temperature sensor.
- Use a multimeter to measure the sensor resistance at room temp.
- Inspect wiring harness and connectors for continuity and secure connection.
- Replace the lower oven temperature sensor if resistance is out of range.
- If sensor and wiring are confirmed good, test control board inputs and replace control board if necessary.
Parts needed: Lower oven temperature sensor, Wiring harness/connectors, Electronic oven control board (if required)
- If you are uncomfortable accessing internal components or measuring electrical values
- If sensor resistance and wiring check out but error persists
- If control board diagnostics are required
