Wine cooler beeps repeatedly or alarm sounds even though temperature and door seem normal.

Safety: Unplug the unit if removing panels.

Steps:

• Check door switch: Ensure the door switch is firmly mounted and not loose. Replace if intermittent.
• Verify temperature: Use a thermometer to confirm actual temperature is within normal range.
• Reset alarm: Press and hold the alarm reset or power button as described in the user manual.
• Power cycle: Unplug for 5–10 minutes to reset the control. If alarms persist, inspect sensors and control board as in E1–E3 and F9.
