The fuse or air switch trips immediately after power on, and the fridge cannot start

可能原因 / Possible Causes： 1. 壓縮機燒毀，導致短路
2. 啟動電容損壞，造成電流過大
3. 內部線路短路，如電機線圈燒毀

1. Compressor burned out, causing short circuit
2. Startup capacitor damaged, causing excessive current
3. Internal wiring short circuit, such as motor coil burnout

解決方案 / Solutions： 1. 使用萬用錶檢測壓縮機阻值，燒毀則更換壓縮機
2. 更換匹配型號的啟動電容，確保電流穩定
3. 排查短路線路，更換損壞線材及部件
4. 檢查電源電壓是否穩定，必要時安裝穩壓器

1. Use a multimeter to test the compressor resistance, replace the compressor if burned out
2. Replace the startup capacitor of the matching model to ensure stable current
3. Troubleshoot the short circuit wiring and replace damaged wires and components
4. Check if the power supply voltage is stable, install a voltage regulator if necessary

故障描述 / Fault Description： 插入電源後，雪櫃無任何反應，燈不亮、風扇不轉、壓縮機不啟動
After plugging in the power, the fridge has no response at all, the light does not turn on, the fan does not rotate, and the compressor does not start

可能原因 / Possible Causes： 1. 電源插座接觸不良或無電
2. 電源線斷路，無法傳輸電力
3. 主板燒毀，無法控制電源供應
4. 電源開關損壞，無法接通電路

1. Poor power socket contact or no power
2. Power cord open circuit, unable to transmit power
3. Motherboard burned out, unable to control power supply
4. Power switch damaged, unable to connect the circuit

解決方案 / Solutions： 1. 更換電源插座或檢測插座電壓，確保供電正常
2. 更換全新電源線，測試電力傳輸
3. 檢測主板電路，燒毀則更換對應型號主板
4. 更換電源開關，確保電路通暢

1. Replace the power socket or test the socket voltage to ensure normal power supply
2. Replace with a new power cord and test power transmission
3. Test the motherboard circuit, replace the corresponding model motherboard if burned out
4. Replace the power switch to ensure smooth circuit

故障描述 / Fault Description： 雪櫃通電後無法正常控制溫度、風扇及壓縮機，按鍵無反饋或亂碼
After the fridge is powered on, it cannot normally control the temperature, fan and compressor, and the buttons have no feedback or garbled codes

可能原因 / Possible Causes： 1. 電壓不穩定，燒毀主板電子元件
2. 雪櫃內部受潮，導致主板短路
3. 長時間使用，主板元件老化損壞
4. 人為操作失誤，導致主板燒毀

1. Unstable voltage, burning out motherboard electronic components
2. Internal moisture of the fridge, causing motherboard short circuit
3. Long-term use, motherboard components aging and damage
4. Human operation errors, causing motherboard burnout

解決方案 / Solutions： 1. 拆卸主板進行專業檢測，確認損壞元件
2. 更換原廠匹配主板，確保功能兼容
3. 安裝穩壓器，避免後續電壓波動損壞主板
4. 對雪櫃內部進行防潮處理，延長主板使用壽命

1. Remove the motherboard for professional testing to confirm damaged components
2. Replace with the original matching motherboard to ensure functional compatibility
3. Install a voltage regulator to avoid subsequent voltage fluctuations damaging the motherboard
4. Perform moisture-proof treatment on the inside of the fridge to extend the service life of the motherboard

故障描述 / Fault Description： 觸摸或按壓雪櫃控制面板按鈕，無任何反應，無法調節溫度或切換模式
Touching or pressing the buttons on the fridge control panel has no response, and the temperature cannot be adjusted or the mode cannot be switched

可能原因 / Possible Causes： 1. 按鈕面板進水或受潮，導致接觸不良
2. 按鈕磨損老化，失去彈性或導電性能
3. 控制面板與主板連接線鬆動或斷路
4. 主板故障，無法接收按鈕信號

1. Button panel water ingress or moisture, causing poor contact
2. Buttons worn and aged, losing elasticity or conductivity
