Freezer beeping intermittently with no obvious error code on display.

Safety first: Ensure the door is closed to prevent condensation and slipping hazards.

• Confirm door closure: Check that nothing is blocking the door from closing fully. Listen for the gasket making full contact.
• Test door switch: Press the switch manually and see if the beeping stops. Replace the switch if it is intermittent or loose.
• Check temperature: Use a thermometer to verify that the freezer is at or below the recommended temperature. If not, troubleshoot cooling performance.
• Reset control: Unplug the freezer for 5 minutes, then plug back in to clear any temporary alarm condition.
