Thermador Oven Error Code E115

If you’ve encountered Thermador oven error code E115, indicating that the upper oven temperature is too high, it’s important to address this issue promptly. In this blog post, we’ll provide a comprehensive guide on how to diagnose and resolve this error code.

Step 1: Disconnect Electrical Power

The first step is to ensure safety by disconnecting electrical power to your Thermador oven. This will prevent any electrical hazards during the troubleshooting and repair process.

Step 2: Check the Electronic Oven Control Board

If the error code appeared because the oven genuinely overheated, it’s likely due to a defective relay in the electronic oven control board. In this case, the control board will need to be replaced.

Step 3: Examine the Upper Oven Temperature Sensor Wire Harness

If the error code appears when the oven isn’t overheating, it’s time to inspect the wire harness connections for the upper oven temperature sensor. Look for loose or damaged wires. Reconnect any loose wires if found, or replace the wire harness if it’s damaged beyond repair.

Step 4: Test the Upper Oven Temperature Sensor

Using a multimeter, measure the resistance of the upper oven temperature sensor. At 70 degrees Fahrenheit, it should read approximately 1,080 ohms of resistance. If the sensor’s resistance deviates significantly from this value, it should be replaced.

Step 5: Replace the Electronic Oven Control Board

If both the sensor’s resistance and the wire harness are in proper working condition, the issue likely lies with the electronic oven control board. Replace it to resolve the error code.

By following these steps, you can effectively troubleshoot and address Thermador oven error code E115, ensuring that your oven operates safely and efficiently. However, if you encounter challenges during this process or if you’re uncertain about your diagnosis, it’s advisable to seek professional assistance.
