如(ru)果不檢查故(gu)障(zhang)原因并強行操(cao)作，會造成電(dian)(dian)路(lu)(lu)(lu)過(guo)(guo)電(dian)(dian)壓或(huo)過(guo)(guo)電(dian)(dian)流，從(cong)而損(sun)(sun)壞一些正(zheng)常(chang)元件。變頻(pin)空調常(chang)用四(si)根保(bao)險(xian)(xian)管(guan)，分別安(an)裝(zhuang)在(zai)室內(nei)控制(zhi)板(ban)(ban)、室外控制(zhi)板(ban)(ban)、電(dian)(dian)源板(ban)(ban)和主電(dian)(dian)源電(dian)(dian)路(lu)(lu)(lu)中。保(bao)險(xian)(xian)管(guan)熔斷通(tong)常(chang)是由相應電(dian)(dian)路(lu)(lu)(lu)分析或(huo)電(dian)(dian)路(lu)(lu)(lu)中的(de)短路(lu)(lu)(lu)引起的(de)。如(ru)果只更換保(bao)險(xian)(xian)管(guan)而不發現故(gu)障(zhang)原因，其部件很可能會因過(guo)(guo)流壓而損(sun)(sun)壞。

變(bian)頻(pin)空(kong)調通(tong)(tong)常(chang)只有2~3個啟動電(dian)容，空(kong)氣量在480~2000uf之間，如電(dian)容擊(ji)穿、斷路(lu)、參數(shu)變(bian)化、電(dian)源電(dian)路(lu)、流等故障(zhang)，損壞部分部件(jian)，使壓縮機無法正常(chang)啟動。變(bian)頻(pin)空(kong)調的維護，要了解電(dian)路(lu)工(gong)作原理(li)和各部件(jian)的正常(chang)參數(shu)，記(ji)錄各關鍵部件(jian)的正常(chang)工(gong)作數(shu)據。故障(zhang)發生(sheng)后，通(tong)(tong)過(guo)測量和比較(jiao)，可以(yi)快(kuai)速發現故障(zhang)并排除。
