E2 - hisense Refrigerator

中文

含义

E2 为冷冻室温度传感器故障。该传感器用于监测冷冻室温度，控制压缩机和化霜。传感器异常会影响冷冻效果，导致食物解冻变质。

常见原因

1. 冷冻传感器热敏电阻老化
2. 传感器线束在超低温下脆化断裂
3. 传感器探头被冰霜覆盖影响测温
4. 插头端子松动
5. 控制板检测通道故障

自助排查

1. 观察冷冻室显示温度是否正常，手动测温对比判断。
2. 断电化霜后找到冷冻室传感器探头位置（通常在蒸发器附近），确认未被冰覆盖。
3. 检查传感器线束是否有断裂或脆化。
4. 用万用表测量传感器阻值，与温度-阻值表对照。
5. 如传感器损坏，需更换同型号配件，建议联系海信售后。

English

Meaning

Freezer compartment temperature sensor fault. This sensor monitors the freezer temperature to control the compressor and defrost cycle.

Common Causes

1. Freezer sensor thermistor aging
2. Sensor wiring harness brittle and cracked at ultra-low temperatures
3. Sensor probe covered in frost affecting temperature reading
4. Plug terminal loose
5. Control board detection channel fault

Self-Check Steps

1. Check whether the freezer temperature display is normal and compare with a manual thermometer reading.
2. After power-off defrosting, locate the freezer sensor probe (usually near the evaporator) and make sure it is not covered by ice.
3. Inspect the sensor wiring harness for cracks or brittleness.
4. Measure sensor resistance with a multimeter and compare against the temperature-resistance table.
5. If the sensor is damaged, replace with the same type; contact Hisense service for assistance.
