Display shows E11; interior lights and display may work but compressor does not start.

Safety: Disconnect power before removing door switch assemblies or control panels.

Procedure:

• 1. Check door lights: Open and close the refrigerator door. If the interior light does not turn off when the door is closed, the door switch may be faulty.
• 2. Locate door switch: On Hansa refrigerators, the door switch is usually located in the door frame near the top or side, or integrated into the control panel.
• 3. Test the switch: Remove the switch by gently prying it out. Disconnect the connector and test continuity with a multimeter while pressing the switch. It should change state (open/closed) when pressed.
• 4. Inspect wiring: Check for broken or loose wires at the switch and along the harness to the control board.
• 5. Replace faulty switch: Install a new refrigerator door switch if the original does not operate correctly.
• 6. Control board: If the switch and wiring are good but E11 remains, the main control board may not be reading the door status correctly and may need replacement.

Note: Some models use magnetic reed switches; ensure the door magnet is present and correctly positioned.
