現象：插電後燈不亮、按鍵無響應。

Symptom:No light after plugging in, no response from buttons.

原因：電源插座接觸不良、保險絲燒斷、電源線斷路。

Cause:Poor power socket contact, blown fuse, power cord disconnection.

處理：更換插座測試，非專業勿拆機內保險絲。

Solution:Test with another socket, do not disassemble internal fuse.

現象：觸摸/機械按鍵按了沒反應、反應遲鈍。

Symptom:Touch/mechanical buttons no response or slow response.

原因：面板積油污、按鍵彈片老化、觸控板故障。

Cause:Oil on panel, aging button springs, touch panel failure.

處理：關機斷電後用乾布清潔按鍵區，嚴重需更換面板。

Solution:Clean buttons with dry cloth after power off, replace panel if serious.

現象：運行正常、有風聲，食物完全不熱。
原因：磁控管損壞、高壓二極體/電容故障、高壓保險絲燒斷。
處理：屬高壓部件，禁止自行拆修，送維修。

Symptom: Runs normally with fan sound, food not heated at all.
Cause: Damaged magnetron, high voltage diode/capacitor failure, blown high voltage fuse.
Solution: High voltage parts, do not repair yourself, send for service.

現象：機器運行、加熱正常，盤子靜止不轉。
原因：轉盤馬達損壞、滾輪脫落/卡滯、傳動軸磨損。
處理：檢查滾輪是否移位、有異物卡阻，馬達損壞需更換。

Symptom: Machine runs & heats normally, turntable not moving.
Cause: Damaged turntable motor, roller fallen/stuck, worn drive shaft.
Solution: Check roller position & foreign objects, replace motor if damaged.

現象：嗡嗡聲、異響、震動聲明顯變大。
原因：風扇葉片卡異物、轉盤不平衡、磁控管老化、機腳墊老化。
處理：清理風扇異物、擺平放穩轉盤。

Symptom: Buzzing, abnormal noise, loud vibration.
Cause: Foreign objects in fan, unbalanced turntable, aging magnetron/feet.
Solution: Clean fan, place turntable properly.

現象：門已關嚴，機器判定門開啟，不能啟動。
原因：門控開關鬆動/損壞、門扣變形、門縫異物卡阻。
處理：清理門縫髒污，門扣變形/開關故障需維修。

Symptom: Door fully closed but machine detects open, cannot start.
Cause: Loose/damaged door switch, deformed door latch, foreign objects in door gap.
Solution: Clean door gap, repair if latch/switch faulty.

現象：運行一會就停機，反覆斷啟。
原因：散熱不良、溫控保護器動作、線路接點鬆動。
處理：清理機身散熱口，保持四周通風。

Symptom: Stops after running for a while, repeated power on/off.
Cause: Poor heat dissipation, thermostat protection, loose wiring.
Solution: Clean vents, keep surrounding ventilation.

現象：觸碰機殼有輕微觸電感。
原因：接地不良、內部線路絕緣層破損、油污導電。
處理：檢查家裡地線，徹底清潔機體油污，故障未排除停止使用。

Symptom: Slight electric shock when touching case.
Cause: Poor grounding, damaged internal wire insulation, conductive oil.
Solution: Check home ground wire, clean oil, stop using if problem remains.

現象：食物一邊燙一邊冷。
原因：轉盤卡滯、微波反射不均、腔體積油影響微波傳導。
處理：清潔爐腔、確保轉盤正常轉動。

Symptom: Food hot on one side, cold on the other.
Cause: Stuck turntable, uneven microwave reflection, oil in cavity.
Solution: Clean oven cavity, ensure turntable works properly.

現象：使用中冒煙、有焦糊味。
原因：爐腔/頂部防護網積油過多、食物濺出燒焦、線路燒蝕。
處理：立即斷電停機，深度清潔油污；持續冒煙送修。

Symptom: Smoke & burnt smell during use.
Cause: Excessive oil in cavity/protective net, burnt food, burnt wiring.
Solution: Power off immediately, deep clean oil; send for repair if smoking continues.
