DIY Steps: 1. Rinse air filter & air dry; 2. Wipe evaporator coil with white vinegar to remove mould; 3. Empty & air-dry tank; 4. Run machine 30 mins regularly to dry interior.

自修方法：1. 斷電十分鐘重置；2. 清洗濾網散熱；3. 檢查溫度感應頭是否脫落。重置後仍報碼需維修更換感應器。

DIY Steps: 1. Unplug 10 mins for full reset; 2. Wash filter for heat dissipation; 3. Check loose temperature sensor probe. Code reappears = sensor replacement needed.

自修方法：1. 斷電清理風扇葉纏繞灰塵毛髮；2. 輕撥風扇葉測試是否卡滯。卡滯嚴重或摩打燒毀需更換零件。

DIY Steps: 1. Unplug & remove hair/dust tangled on fan blade; 2. Spin blade manually to check jamming. Seize or burnt motor requires replacement.

自修方法：1. 關機待霜自然融化；2. 清洗濾網改善風量；3. 室溫低於18度會容易結霜。持續結霜為化霜感應故障。

DIY Steps: 1. Power off to melt ice naturally; 2. Clean filter to boost airflow; 3. Low room temp below 18°C causes frost. Persistent icing = defrost sensor failure.

自修方法：1. 更換全新電池；2. 擦拭遙控紅外發射頭；3. 擦乾機身接收窗口灰塵。仍無反應為接收板故障。

DIY Steps: 1. Replace remote batteries; 2. Wipe infrared emitter lens; 3. Clean receiver window dust on machine. Still faulty = receiver board repair.

自修方法：1. 清潔機身濕度感應孔灰塵；2. 斷電重置。數值持續不動需更換濕度感應器。

DIY Steps: 1. Clean dust from humidity sensor vent; 2. Full power reset. Stuck reading requires humidity sensor replacement.

自修方法：1. 擦拭水箱偵測金屬觸片；2. 檢查機身彈簧觸點是否卡住。彈簧損壞需要維修更換。

DIY Steps: 1. Wipe metal contact strips on tank; 2. Check stuck spring contacts on chassis. Broken spring needs replacement.

自修方法：1. 徹底清洗濾網及蒸發器；2. 關閉窗戶減少室外濕氣流入。改善有限代表雪種洩漏。

DIY Steps: 1. Deep clean filter & evaporator coil; 2. Close windows to block outdoor humid air. Minimal improvement = refrigerant leakage.

自修方法：立即斷電停止使用，切勿自行拆解。多為線路短路、壓縮機短路，需專業維修檢查。

DIY Steps: Unplug immediately & stop usage. Do not disassemble. Usually short circuit wiring or compressor short, professional inspection required.

自修方法：1. 重置機器設定回復原廠；2. 清潔濕度感應孔。設定失效為主板程式或感應器故障。

DIY Steps: 1. Factory reset machine settings; 2. Clean humidity sensor vent. Unstable setting = mainboard or sensor defect.

自修方法：1. 移除周圍阻礙散熱物品；2. 清洗髒濾網。持續過熱會觸發保護停機，嚴重會燒毀零件。

DIY Steps: 1. Clear surrounding blockages for ventilation; 2. Wash clogged filter. Overheating triggers auto shutdown and may burn internal parts.
