Display shows E10 and the door alarm may sound even when the door is closed; cooling may stop after some time.

Safety: Disconnect power before removing door trims or control panel components.

• Check door closure: Ensure the door closes fully and the gasket is not obstructing. Gently press the door to see if the alarm stops.
• Locate door switch: On Balay wine coolers, the door switch may be a small plunger switch in the frame or a hidden magnetic reed switch near the top or side.
• Test switch: If accessible, press the mechanical switch and listen for a click. For magnetic switches, move a magnet near the sensor and see if the alarm stops.
• Inspect magnet: Verify the magnet embedded in the door frame is present and aligned with the sensor. Reposition or replace if missing.
• Electrical test: With the unit unplugged, disconnect the switch and test continuity while actuating it. Replace the switch if it does not change state.
• Control board: If the switch and wiring are good, the door input on the PCB may be faulty and require board replacement.
