CH16 - lg Air Conditioner

中文

含义

CH16 表示外机正在进行除霜运行，这是正常的工作模式，不是故障。

常见原因

1. 外环温度低，外机换热器结霜。
2. 空调自动进入除霜模式以保持制热效果。
3. 制热模式下周期性发生的正常现象。

自助排查

1. 这是正常现象，无需担心，空调在5-15分钟后会自动恢复制热。
2. 除霜期间外机可能会停止运转，内机风扇也可能停止，这是正常的。
3. 如果除霜显示过于频繁或时间过长，可能是制冷剂不足或系统问题，请联系LG售后检查。

English

Meaning

CH16 indicates the outdoor unit is running a defrost cycle. This is a normal operation mode, not a fault.

Common Causes

1. Low outdoor ambient temperature causes frost buildup on the outdoor coil.
2. The unit automatically enters defrost mode to maintain heating efficiency.
3. Normal operation that occurs periodically during heating mode.

Self-Check Steps

1. This is a normal operation — the AC will automatically resume heating within 5-15 minutes.
2. During defrost, the outdoor unit may stop running and the indoor fan may stop. This is normal.
3. If defrost occurs too frequently or takes too long, it may indicate a refrigerant shortage or system issue — contact LG service.
