含义
E3 为控制板环境温度传感器故障。该传感器通常位于主控板上，用于检测冰箱安装环境温度，参与压缩机保护逻辑。
常见原因
- 控制板上环境温度传感器损坏
- 传感器焊接点虚焊
- 控制板受潮导致传感器电路异常
- 传感器被灰尘覆盖影响测温
自助排查
- 检查冰箱安装环境是否过于潮湿或有水源靠近。
- 断电后打开冰箱背部控制板盖，检查控制板是否有水渍或灰尘。
- 用干布或毛刷清洁控制板表面灰尘。
- 如控制板有明显水渍或腐蚀，需更换控制板，联系海信售后。

Meaning
Ambient temperature sensor on the control board fault. This sensor is typically located on the main control board and detects the installation environment temperature.
Common Causes
- On-board ambient temperature sensor damaged
- Sensor solder joint cold-soldered
- Control board moisture ingress affecting sensor circuit
- Sensor covered in dust affecting temperature reading
Self-Check Steps
- Check whether the refrigerator installation environment is overly humid or near a water source.
- Power off, open the rear control board cover, and inspect the board for water stains or dust.
- Clean the control board surface dust using a dry cloth or brush.
- If the control board shows obvious water damage or corrosion, it needs replacement; contact Hisense service.
