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。

Cannot reach set temperature, 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 display, no fan sound, mostly caused by faulty power board, blown fuse or loose wiring.

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。

Inconsistent temperature due to damaged thermostat, sensor or mainboard failure.

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 caused by worn fan bearing, aging compressor mount or loose 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。

Leakage due to 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。

Ice buildup due to defrost system failure or worn-out 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 gasket causes cool air loss, high power consumption and frost buildup.

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。

Flickering or no light due to damaged LED, loose wiring 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 due to 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 running with high power consumption, caused by sensor or mainboard failure.

✅ 建議維修：

機齡5年以內、故障屬於零件更換（雪種、風扇、門封、感溫器、電源板），維修成本遠低於購買新機，環保又划算。

❌ 建議更換：

機齡超過8-10年、壓縮機完全損壞、多個核心部件同時故障、維修費用超過新機50%。

✅ Recommend Repair:

Age under 5 years, issue is part replacement (fan, seal, sensor, board). Cost much lower than new machine, eco-friendly.

❌ Recommend Replace:

Age over 8-10 years, compressor failure, multiple core parts broken, repair cost over 50% of new machine.
