含义
烤箱门锁故障。E5 表示主控芯片检测到门锁（自锁装置）状态异常——门锁电机或微动开关未能正确反馈门的锁定/解锁状态。
常见原因
- 门锁电机卡死（食物残渣或油污进入锁舌机构）
- 门锁微动开关触点氧化或位置偏移，状态信号错误
- 门锁连接器松动或线束被门铰链夹断
- 门锁电机线圈烧毁或驱动三极管损坏
- 门安装不正导致锁舌与锁扣无法对齐
- 主控板门锁检测电路故障
自助排查
- 断电重启：拔掉电源插头等待 5 分钟后重新插电，看代码是否消失
- 检查门安装：观察烤箱门是否安装到位，上下左右是否对齐；门变形或铰链松动会影响锁舌对准
- 清洁锁舌机构：用干布清洁门锁锁舌及其周围的油污和食物残渣，确保锁舌能自由伸缩
- 听锁动作声音：在烤箱进入自锁程序时贴近门锁区域，听是否有电机转动声；完全无声可能电机或驱动电路故障
- 呼叫售后：门锁机构涉及安全联锁，建议联系 Robam 售后（9510-5855）更换门锁总成
English
Meaning
Oven door lock fault. E5 indicates the main control chip detects an abnormal door lock status — the lock motor or micro-switch fails to correctly report the locked/unlocked state.
Common Causes
- Stuck door lock motor (food debris or grease entering the latch mechanism)
- Oxidized or misaligned door lock micro-switch contacts providing incorrect status
- Loose door lock connector or harness pinched by door hinge
- Burned-out door lock motor coil or damaged drive transistor
- Misaligned door installation preventing latch alignment
- Faulty door lock detection circuit on main board
Self-Check Steps
- Power cycle: Unplug the oven for 5 minutes, then reconnect to see if the code clears
- Check door alignment: Inspect whether the oven door is properly seated and aligned on all sides. Misaligned hinges affect latch engagement
- Clean latch mechanism: Use a dry cloth to remove grease and food debris around the door lock latch, ensuring it moves freely
- Listen for motor: When the oven enters self-lock mode, listen near the lock area for a motor whirring sound. Complete silence suggests a motor or drive circuit fault
- Call support: The door lock mechanism is a safety interlock device. Contact Robam after-sales service (9510-5855) for door lock assembly replacement
