E1 - 海信 冰箱

中文

含义

E1 为冷藏室温度传感器开路或短路。该传感器检测冷藏室实际温度，用于控制冷藏风门和压缩机启停。传感器异常会导致冷藏室温度失控，食物保鲜受影响。

常见原因

1. 传感器热敏电阻老化开路或短路
2. 传感器连接线被冰水浸泡导致接触不良
3. 传感器插头端子氧化
4. 控制板检测电路异常
5. 线束在发泡层内断裂

自助排查

1. 检查冷藏室温度显示是否与实际感受一致，偏差过大说明传感器可能异常。
2. 断电后打开冷藏室背板，找到温度传感器（通常为白色探头），检查外观和连接。
3. 拔下传感器插头，用万用表测量阻值，常温约 2-5kΩ（因型号而异）。
4. 如传感器正常，检查控制板端接口有无腐蚀或烧痕。
5. 传感器更换需注意线束走线，避免被冷凝水浸泡。

English

Meaning

Fresh food compartment temperature sensor open or short circuit. This sensor detects the actual temperature in the fresh food compartment and controls the damper and compressor cycling.

Common Causes

1. Sensor thermistor aging - open or short circuit
2. Sensor connection wire soaked in ice water causing poor contact
3. Sensor plug terminal oxidized
4. Control board detection circuit abnormal
5. Wiring harness broken inside the foam insulation

Self-Check Steps

1. Check whether the fresh food compartment temperature display matches the actual feel; a large discrepancy suggests a sensor fault.
2. Power off, open the fresh food compartment rear panel, locate the temperature sensor (usually a white probe), and inspect its condition and connection.
3. Disconnect the sensor plug and measure resistance with a multimeter; room temperature should be 2-5kΩ (varies by model).
4. If the sensor is normal, check the control board connector for corrosion or burn marks.
5. When replacing the sensor, route the wiring harness carefully to avoid condensate water exposure.
