问开利30HXC300A中央空调故障代码20怎么处理

你好！检查b1回路的油位，油压传感器和接线，把b1的油压传感器接线接和其他的回路上接线对调接，看下故障代码有什么变化我的回答你还满意吗~~

此类问题一般为传感器数据传输故障，报警20代表油压传感器传输数据失败。这种型号的中文版故障代码没有找到，英文故障代码如下：仅供参考ALARMCODE20 Oil pressure transducer failure, compr B1WHY WAS THISALARM GENERATED?Measured signal = 0V dcACTION TAKEN BYTHE CONTROLCompressor B1 shut downRESET TYPEAuto, if the temperaturemeasured by the sensorbecomes normal againPROBABLECAUSEDefectivetransducer, wiringfault
