當然(ran)，溢流閥也有可能(neng)被堵塞。也會(hui)有高壓(ya)(ya)報(bao)(bao)警(jing)，但(dan)是(shi)這種常見(jian)的故障是(shi)服務器一旦(dan)啟動，服務器一運行就會(hui)報(bao)(bao)警(jing)。與前面幾類不同(tong)，這里也提(ti)到，如果發(fa)出底壓(ya)(ya)報(bao)(bao)警(jing)，一般是(shi)制冷(leng)劑泄漏造成的。也有可能(neng)是(shi)溫(wen)降過低，導致(zhi)空(kong)調(diao)蒸發(fa)器工作壓(ya)(ya)力降低超過原廠**工作壓(ya)(ya)力設置，也導致(zhi)底壓(ya)(ya)報(bao)(bao)警(jing)！
