溫度降不下來、酒溫長期偏高，多為雪種不足、冷凝器積塵、壓縮機老化。

Temperature cannot drop, usually due to insufficient refrigerant, dusty condenser, or aging compressor.

插電不開機、屏幕黑屏、無風扇聲，常見電源板故障、保險絲燒毀、線路接觸不良。

No power, black screen, no fan sound: power board failure, blown fuse, or poor wiring connection.

忽冷忽熱、無法恆溫，多是溫控器、感溫探頭損壞，主板數據失準。

Fluctuating temperature: faulty thermostat, temperature sensor, or mainboard error.

運行轟鳴、嗡嗡聲、雜音大，風扇軸承磨損、壓縮機懸膠老化、內部配件鬆動。

Loud humming noise: worn fan bearing, aging compressor mounts, loose internal parts.

底部漏水、內層滴水，排水孔堵塞、化霜系統故障、門封漏氣結霜融化。

Water leakage: clogged drain, defrost system failure, or door seal leakage.

內壁結霜結冰無法正常使用，自動除霜模組故障、門封老化漏冷氣。

Heavy ice buildup: defective defrost module or aging door seal.

門膠條變形發硬、密封不緊，冷氣流失、耗電大增、容易結霜。

Deformed door seal: air leakage, high power consumption, easy frosting.

櫃內照明不著、時亮時滅，燈泡損壞、燈帶線路接觸不良、開關故障。

Light not working or flickering: damaged bulb, loose wire, or faulty switch.

調溫按唔到、面板卡死、亂跳數，觸控板受潮、主板按鍵模組損壞。

Unresponsive panel: moisture damage or mainboard control module failure.

24小時一直轉唔停、耗電嚴重，溫控探頭失效、主板故障、製冷系統異常。

24hr continuous running: faulty sensor, mainboard failure, or cooling system error.
