Alarm beeping and door-open indicator active even when doors are closed.

Safety: Unplug the appliance before working on switches or wiring.

Steps:

• Check door closure: Verify that nothing obstructs the door and that it closes flush with the cabinet.
• Test door switch: Manually operate the switch and listen for the alarm to stop. If it does not, test and replace the switch as needed.
• Magnetic systems: Ensure the magnet in the door is present and aligned with the sensor area.
• Inspect hinge wiring: On models with wiring through the hinge, check for broken or frayed wires and repair or replace the harness.
