But also according to the emergency switch to start the normal cooling, open the panel, remote control board close to the receiver at the end of the occasional boot, multiple tests and found that sometimes show 11, it is estimated that the fault code , Replace the receiver head is invalid, for universal control of the same failure, measured 5 volts to 4.96 volts, according to the remote control when the receiver signal pin 3 o'clock to 4 o'clock to a few volts of the switching voltage, measured display board to the motherboard Of the normal line, visual display board and the motherboard clean without mold, for crystal is also invalid. Why does this machine control failure?
接修科龙变频挂机摇控开机不灵，但按应急开关开机正常制冷，拆开面板，摇控板近距离对准接收头偶尔能开机，多次试验，发现有时显示11，估计是故障代码，代换接收头无效，换万能摇控故障不变，测5伏为4.96伏，按摇控时接收头信号脚有3点几伏到4点几伏的跳变电压，测显示板到主板的线路正常，目测显示板与主板干净无霉变，换晶振也无效。此机为何摇控失灵？
