Unit beeps intermittently without any visible error code.

Safety: No internal work is required for basic checks.

• Check door: Ensure the door is fully closed and sealing properly.
• Monitor temperature: Use a thermometer to verify if the interior is too warm or too cold.
• Power reset: Unplug for 5 minutes to reset the alarm logic.
• Door switch: If beeping continues with door closed, have the door switch and control board inspected and replaced if necessary.
