F3 E1 - 美泰克 烤箱

中文

含义

烤箱温度传感器（RTD）短路——电阻过低

常见原因

1. RTD 探头内部短路
2. 传感器线束被挤压并与底盘短路
3. 连接器受潮导致短路

自助排查

1. 在控制板处断开 RTD 传感器，测量电阻（室温下约 1080Ω）
2. 检查传感器线束绝缘是否被挤压破损
3. 电阻低于 500Ω 表示传感器短路

English

Meaning

Oven temperature sensor (RTD) shorted — resistance too low

Common Causes

1. RTD probe internally shorted
2. Sensor wiring pinched and shorted to chassis
3. Connector moisture causing short

Self-Check Steps

1. Disconnect RTD at control board, measure resistance (~1080Ω at room temp)
2. Inspect sensor wiring for pinched insulation
3. Less than 500Ω indicates short
