What is error code 21 on Thermador?
Error code 21 on a Thermador appliance typically indicates a temperature sensor or temperature sensor circuit malfunction. This error is commonly associated with Thermador ovens, particularly wall ovens, and ranges. The temperature sensor, also known as a thermostat or probe, plays a crucial role in monitoring and regulating the oven's temperature during cooking. When the temperature sensor or its circuit malfunctions, it can lead to inaccurate temperature readings or a failure to communicate with the oven's control board. As a result, the oven may not heat properly or may display error code 21 to alert users of the issue. To troubleshoot and resolve error code 21, follow these steps: 1. Power cycle: Turn off the oven and unplug it from the power source for a few minutes. Then, plug it back in and turn it on again. Sometimes, this simple reset can clear temporary glitches and resolve the error. 2. Check the sensor: Inspect the temperature sensor for any visible damage or loose connections. If you find any issues, such as frayed wires or a broken sensor, consider replacing it with a new one. 3. Test the sensor's resistance: Use a multimeter to test the temperature sensor's resistance. Compare the readings with the manufacturer's specifications in the user manual. If the readings are out of range, the sensor may need replacement. 4. Professional assistance: If you are unsure or unable to perform these checks yourself, it's best to contact a qualified technician or Thermador service center to diagnose and repair the issue accurately. Remember that error codes can vary depending on the specific model and year of your Thermador appliance. Always refer to the user manual or contact Thermador's customer support for precise information and troubleshooting steps for your particular appliance model.
