Thermador Refrigerator Error Code E11

Error code E11 on your Thermador refrigerator signifies a software or firmware error in the display module. This code indicates a communication breakdown between the appliance’s control system and the display module. When this error occurs, it can lead to inaccurate temperature readings, unresponsive controls, or even a blank display.

Diagnosing the Issue:

Before proceeding with any repairs, it’s essential to identify the problem accurately. Here’s how you can diagnose error code E11:

1. Power Cycle: Start by unplugging your refrigerator or switching off the circuit breaker that supplies power to it. Leave it off for a few minutes and then turn it back on. Sometimes, a simple power cycle can reset the error.
2. Check for Loose Connections: Inspect the wiring connections between the control board and the display module. Loose or damaged wires can cause communication errors. Ensure all connections are secure.

If a power cycle and connection check don’t resolve the issue, you might need to reset or replace the display module. Here’s how to proceed:

1. Reset the Display Module:

   • Press and hold the “Reset” or “Cancel” button on the display module for about 10 seconds.
   • Release the button, and the display should reset. Check if the error code has cleared.
