含义
E2 为室内盘管温度传感器故障。该传感器检测蒸发器盘管温度，用于防结霜和制热防冷风控制，传感器故障将影响空调正常运行。
常见原因
- 盘管传感器热敏电阻老化或损坏
- 传感器引线断裂或插头接触不良
- 传感器受潮导致阻值偏移
- 控制板检测回路异常
- 安装时传感器未完全插入盘管
自助排查
- 断电后打开室内机面板，找到蒸发器盘管上的传感器
- 检查传感器插头是否牢固连接
- 测量传感器阻值（正常 5-20kΩ 随温度变化）
- 如阻值异常，更换同型号盘管传感器
- 更换后仍报故障，联系奥克斯售后检修
English
Meaning
Indoor coil temperature sensor fault. The sensor detects the evaporator coil temperature for anti-freeze and heating anti-cold-draft control.
Common Causes
- Coil thermistor aging or damage
- Sensor lead wire broken or connector loose
- Moisture causing resistance drift
- Control board detection circuit fault
- Sensor not fully inserted during installation
Self-Check Steps
- Power off and open the indoor unit panel, locate sensor on evaporator coil
- Check sensor connector is firmly seated
- Measure sensor resistance (normally 5-20kΩ depending on temperature)
- If abnormal, replace with same coil sensor type
- If fault persists, contact AUX after-sales service
