Wine cooler displays d1 or a door icon and beeps continuously even when the door appears closed.

Safety: No internal electrical work is required for basic checks, but unplug the unit if removing door trims.

Steps to address d1:

• Check door closure: Ensure the door closes fully and latches magnetically. Look for items or shelves preventing full closure.
• Inspect gasket: Run a thin strip of paper around the door seal; if it pulls out easily in spots with the door closed, the gasket may be warped or compressed. Replace if necessary.
• Verify door alignment: Check that the door is level and square with the cabinet. Adjust hinges if the door is sagging or rubbing.
• Check door magnet and sensor: Confirm the magnet is present in the door edge and aligned with the sensor in the frame. Replace missing magnet or faulty sensor as needed.
• Reset alarm: After correcting mechanical issues, close the door firmly and allow the alarm to reset. If d1 persists, test and replace the door switch.
