The wine cooler beeps continuously or intermittently without any visible error code.

Safety: No immediate electrical hazard, but unplug the unit before opening panels.

Steps:

• Check door: Ensure the door is fully closed and the gasket is sealing properly. Adjust hinges if the door is sagging.
• Test door switch: Press the door switch manually; if the beeping stops, adjust or replace the door switch.
• Temperature: If many warm bottles were recently loaded, allow several hours for the temperature to stabilize; the alarm may clear automatically.
• Keypad: Inspect the control panel for stuck buttons. Gently clean around the buttons and ensure none are jammed.
• Control board: If the alarm persists with the correct temperature and the door closed, the alarm circuit on the main control PCB may be faulty and require replacement.
