中文
含义
线频率不匹配——输入电源频率超出预期 60Hz 范围
常见原因
- 发电机供电频率不稳定
- 逆变器电源
- 电网频率严重波动
- 控制板电源电路故障
自助排查
- 确认烤箱连接到标准市电而非发电机
- 检查同一电路上的其他电器是否有问题
- 测量插座线路频率（须为 60Hz ±2Hz）
- 如使用发电机请切换至市电
English
Meaning
Line frequency mismatch — incoming power frequency outside expected 60Hz range
Common Causes
- Generator power supply with unstable frequency
- Inverter power source
- Severe grid frequency fluctuation
- Control board power supply circuit fault
Self-Check Steps
- Verify oven connected to standard utility power not generator
- Check if other appliances on same circuit have issues
- Measure line frequency at outlet (must be 60Hz ±2Hz)
- If on generator switch to mains power
