如果您的 Lennox 炉出现故障,您需要了解以下信息。
伦诺克斯 (Lennox) 炉子上的闪烁灯代表什么意思?

与特灵 (Trane) 和阿玛纳 (Amana) 一样,伦诺克斯 (Lennox) 暖气炉也配备了 LED 指示灯,用于指示故障。然而,与特灵 (Trane) 和阿玛纳 (Amana) 暖气炉不同的是,伦诺克斯 (Lennox) 暖通空调系统使用红绿灯来指示错误代码。这些灯会以特定的闪烁模式来指示特定问题。
如果您的 Lennox 炉上的红灯和绿灯同时闪烁(快速或缓慢),则表示炉子运行正常。所有其他模式都表示存在问题,可能需要炉子维修。
如何读取 Lennox 错误代码?
Lennox 错误代码是根据闪烁的灯的颜色和闪烁的速度来读取的。
