廚房煮飯油煙倒灌、散不走，主要原因：風輪積油、電機老化、安裝高度不對、濾網長期未清洗。

Kitchen fumes backflow, mainly caused by: fan wheel oil buildup, motor aging, wrong installation height, long-term uncleaned filters.

運轉轟轟響、機身震動，常見原因：風輪變形、螺絲鬆動、電機軸承磨損、安裝不穩固。

Loud operation and vibration, common causes: deformed fan wheel, loose screws, motor bearing wear, unstable installation.

觸控不靈、按了沒反應、自動亂跳檔，核心原因：面板受潮、電路板老化故障、線路接觸不良。富士皇抽油煙機觸控模塊屬於常年易損部件，專業維修即可恢復正常。

Unresponsive touch control, auto gear shift, main causes: panel moisture, circuit board aging, poor circuit contact. Fujioh touch panel is a vulnerable part, professional repair can restore normal function.

插電沒反應、燈不亮、無法啟動，故障原因：電源板損壞、保險絲燒毀、內部線路短路燒毀。

No response after plugging in, no lights, cannot start, causes: power board damage, blown fuse, internal circuit short circuit.

底部滴油、外殼滲油、油杯滿溢，主要原因：油路堵塞、風輪積油過厚、油杯長期未清理。

Oil dripping from bottom, shell oil leakage, full oil cup, main causes: oil passage blockage, thick oil on fan wheel, long-term uncleaned oil cup.

燈不亮、閃爍、忽明忽暗，故障原因：燈珠燒毀、驅動板故障、線路接觸不良。

Lights not on, flickering, causes: lamp bead burnout, driver board failure, poor circuit contact.

一鍵清洗沒反應、噴水異常、洗完仍油膩，原因：清洗泵損壞、管路堵塞、控制程式故障。

Unresponsive one-key cleaning, abnormal water spray, still oily after cleaning, causes: cleaning pump damage, pipeline blockage, control program failure.

開機有燒焦味、刺鼻異味，原因：電機過熱、內部積油高溫燒烤、線路老化絕緣破損。

Burning smell when turned on, causes: motor overheating, high-temperature burning of internal oil, aged circuit insulation damage.

✅ 建議維修：

觸控面板、電路板、電機、風輪等局部故障，維修成本遠低於購買新機，環保節省，當日即可修復使用。

✅ Recommend Repair:

Partial faults such as touch panel, circuit board, motor, fan wheel. Repair cost is much lower than new hood, eco-friendly and repairable on the same day.

❌ 建議更換：

機齡超過10-15年、多個核心部件同時損壞、外殼嚴重生鏽變形，更換新機性價比更高。

❌ Recommend Replacement:

Hood age over 10-15 years, multiple core parts damaged at the same time, serious shell rust and deformation, new hood is more cost-effective.
