Door alarm sounds even when the door appears closed.

Safety: No internal electrical work is required for basic checks.

Steps:

• 1. Check for obstructions: Ensure no containers or shelves are preventing full closure.
• 2. Inspect alignment: Verify that the door is level and lines up with the cabinet. Adjust hinges if necessary.
• 3. Test door switch: Press the door switch manually; the alarm should stop. If not, the CDA door switch or sensor may be faulty and should be replaced.
• 4. Gasket check: Replace a deformed gasket that prevents proper sealing.

Note: Persistent false alarms after these checks may indicate a control board issue.
