Error codes are like a DIY shortcut—they help you locate the source and nature of your appliance issues. Thermador ovens are designed to display error codes when a malfunction is detected, and while the codes may look confusing at first glance, they’re actually pretty simple. Read on to find out the most common error codes and how to fix them!

Before you begin

Before looking into the meaning behind individual Thermador oven error codes, we recommend trying to reset your oven. Sometimes, an error code can be triggered mistakenly due to a power surge or outage, and in these cases, resetting your oven will restore normal function. To do this:

  • Cut power to your Thermador oven. You can either unplug it or, if it is hardwired, flip the corresponding circuit breaker to the “off” position. 
  • Leave your oven without power for at least five minutes to allow the electronics to fully reset. 
  • Restore power to your oven. 
  • Check to see if the error code has cleared. If it has, try heating it to medium heat to check if the code recurs. If not, the issue was likely a glitch and has now been fully resolved. 

Error Code E1 – Control board failure

This error code indicates a failure in your oven’s control board. The solution is to replace the faulty control board with a functional one, which may be outside your comfort zone as a DIYer! If you encounter this error code, we recommend calling a professional, or if you are comfortable doing so, you can source a replacement control board and replace it yourself. 

Error codes E2, E3 and E4 – Temperature sensor fault

This code indicates that the temperature sensor is either not calibrated or has shorted. If resetting your oven doesn’t get rid of the error code, the temperature sensor likely needs replacing. To do this:

  • Disconnect your oven from its power source. 
  • Locate the temperature sensor (refer to your Thermador manual for help if needed). 
  • Use a multimeter to test the sensor for continuity. When tested at room temperature, it should read around 1080 ohms. A reading that varies from this indicates the sensor needs to be replaced. 
  • Source a replacement sensor, ensuring it is compatible with your model of Thermador oven. 
  • Remove the faulty sensor and install the new, working sensor in its place. 
  • Restore power to your oven and test it to ensure the error code doesn’t come back. 

Error Code E6 – High temperature

This error code indicates that your oven has detected a higher temperature than it should be. This can be due to a faulty temperature sensor, but can also be due to malfunctioning heating elements. If this error code occurs:

  • Test the temperature sensor in the manner outlined in the step above. Replace if necessary.
  • Inspect the bake and broil heating elements for damage that could cause them to malfunction. Use a multimeter to check that the heating elements are functioning, and replace them if necessary. 

Error code E7 – High temperature during cleaning cycle

This code indicates that your Thermador oven has reached a high temperature during a self-cleaning cycle. Self-cleaning gets your oven to an extremely high temperature (up to 900°F), which works to burn away dirt and debris, allowing it to be easily wiped away. As these very high temperatures can be dangerous, your Thermador oven will lock while the cleaning cycle is on, preventing it from being opened.

If your oven is displaying this error code, wait for it to cool down to room temperature and then check to see if you can open it. If the error code persists, it may indicate an issue with the control board. 

Error codes E9 or E11 – Door latch issue

These error codes usually indicate a problem with the oven’s door latches, meaning that the door latch or the wiring must be replaced. If this error occurs:

  • Try resetting the oven to see if the error code clears. 
  • Ensure the selector knob is fully set to the “off” position. Try turning it fully on and then off to ensure it is in the right spot. 
  • If the error code persists, the door latch may need to be replaced. You can source a replacement part, ensuring it is compatible with your Thermador oven model, and then either replace it yourself or hire a professional technician to do it for you. 

Error code E13 – Latch motor or control board error

An E13 error code usually indicates a problem with the latch motor, which controls the door latch, but may also suggest a problem with the control board itself. To resolve this issue, try the following:

  • Attempt to reset your oven by cutting the power for at least five minutes. 
  • Make sure the oven is fully switched to the “off” position. 
  • Test the latch motor with a multimeter to see if it is functional. If the multimeter shows no continuity, the latch motor will need to be replaced. 

When to call a professional

Whether or not to call in a professional technician is a personal decision that depends on your expertise level. If you’re inexperienced with electrical DIY, you may prefer to seek professional help in all circumstances. At the same time, if you have experience, you may feel comfortable attempting major repairs like replacing the control board. The most important rule of thumb is to never attempt repairs you are not qualified for and to err on the side of caution and safety in all circumstances.
