E19 error; unit may not recognize door open/close events correctly, affecting lights and alarms.

Safety: Unplug the unit before adjusting or replacing door sensors.

Steps:

• Check magnet alignment: Ensure the magnet embedded in the door aligns directly with the sensor in the cabinet frame when closed. Adjust door or sensor position if necessary.
• Test magnet strength: If the magnet is weak or cracked, replace it with the correct Thermador part.
• Sensor test: Remove the sensor and test with a multimeter or follow service manual procedure for Hall sensor testing. Replace if it does not change state when exposed to the magnet.
• Control logic reset: After hardware checks, perform a power reset. If E19 persists, the main control board may require replacement.
