Freezer shows E11 and door alarm may not function correctly; interior light may behave erratically.

Safety: Unplug the freezer before testing or replacing switches.

• 1. Check door light behavior: Open and close the door and observe the interior light. If it stays on or off regardless of door position, suspect the door switch.
• 2. Locate the door switch: On Siemens freezers, this may be a plunger switch in the cabinet frame or a hidden magnetic reed switch behind the liner, triggered by a magnet in the door.
• 3. Inspect magnet alignment: If a magnetic system is used, ensure the magnet in the door trim is present and aligned with the switch area. Replace missing magnets.
• 4. Test switch continuity: Remove the switch (if mechanical) and test with a multimeter while pressing and releasing the plunger. Replace if it does not change state reliably.
• 5. Check wiring at hinge area: For models with wiring through the door hinge, inspect for broken or frayed conductors that could interrupt the door signal.
• 6. Replace faulty components: Install a Siemens-compatible door switch or repair the harness as needed.
• 7. Reassemble and test: Restore power and verify that the light and door alarm operate correctly and E11 is cleared.

Warning: Do not bypass the door switch permanently; it is part of the safety and control logic.
