華帝燃氣熱水器電源指示燈不亮的原因

 華帝燃氣熱水(shui)器電源指示(shi)燈不(bu)亮的原因

(2)電(dian)(dian)源指(zhi)示(shi)燈(deng)壞 電(dian)(dian)源有電(dian)(dian)，僅僅電(dian)(dian)源指(zhi)示(shi)燈(deng)不亮，此時(shi)并(bing)不影響熱(re)水器的使用。

(3)電(dian)源(yuan)三眼插座中的(de)地(di)線(xian)(xian)(xian)(xian)帶電(dian) 強排式熱(re)(re)水(shui)(shui)器(qi)一般都用三芯電(dian)源(yuan)線(xian)(xian)(xian)(xian)供電(dian)，并且其中接(jie)地(di)線(xian)(xian)(xian)(xian)一般都與熱(re)(re)水(shui)(shui)器(qi)外殼(ke)（也包括(kuo)燃燒(shao)器(qi)及(ji)熱(re)(re)交換(huan)器(qi)）相(xiang) 接(jie)零(ling)連(lian)(lian)。安(an)裝后，熱(re)(re)水(shui)(shui)器(qi)外殼(ke)又(you)通(tong)過(guo)進出水(shui)(shui)金屬軟管與自來(lai)(lai)水(shui)(shui)管相(xiang)連(lian)(lian)。如果電(dian)源(yuan)三眼插座中的(de)地(di)線(xian)(xian)(xian)(xian)帶電(dian)，則當熱(re)(re)水(shui)(shui)器(qi)的(de)電(dian)源(yuan)插頭插入電(dian)源(yuan)插座時，電(dian)源(yuan)地(di)線(xian)(xian)(xian)(xian)中的(de)電(dian)流被(bei)連(lian)(lian)接(jie)到自來(lai)(lai)水(shui)(shui)管而(er)短路。輕者將(jiang)保(bao)險絲燒(shao)斷，嚴重時還(huan)將(jiang)熱(re)(re)水(shui)(shui)器(qi)電(dian)源(yuan)線(xian)(xian)(xian)(xian)中的(de)地(di)線(xian)(xian)(xian)(xian)燒(shao)斷（這時火線(xian)(xian)(xian)(xian)及(ji)零(ling)線(xian)(xian)(xian)(xian)往(wang)往(wang)還(huan)完好）。

(4)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)曾(ceng)經發(fa)生過異常（如曾(ceng)出現過380V的(de)電(dian)(dian)(dian)壓(ya)） 因一般熱水(shui)器的(de)電(dian)(dian)(dian)源(yuan)部(bu)分都安裝(zhuang)有壓(ya)敏(min)電(dian)(dian)(dian)阻（過壓(ya)保護(hu)器），外部(bu)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)過高時(shi)該壓(ya)敏(min)阻將燒壞（詳見“關鍵部(bu)件”一章）o由于(yu)壓(ya)敏(min)電(dian)(dian)(dian)阻燒壞后其電(dian)(dian)(dian)阻接近(jin)(jin)于(yu)零，使電(dian)(dian)(dian)源(yuan)接近(jin)(jin)于(yu)短路(lu)，因此(ci)此(ci)時(shi)熱水(shui)器中的(de)電(dian)(dian)(dian)源(yuan)保險絲(si)也將燒斷。更(geng)換電(dian)(dian)(dian)源(yuan)保險絲(si)及(ji)壓(ya)敏(min)電(dian)(dian)(dian)阻之前，必須先排除外部(bu)電(dian)(dian)(dian)源(yuan)的(de)故(gu)障。

(5)電(dian)(dian)源變(bian)(bian)壓(ya)(ya)(ya)器(qi)燒(shao)(shao)壞(huai) 電(dian)(dian)源電(dian)(dian)壓(ya)(ya)(ya)異常可(ke)(ke)燒(shao)(shao)壞(huai)電(dian)(dian)源變(bian)(bian)壓(ya)(ya)(ya)器(qi)。另外(wai)，電(dian)(dian)源變(bian)(bian)壓(ya)(ya)(ya)器(qi)制(zhi)(zhi)作(zuo)過程中如浸漆處理(li)不好，防潮性能差(cha)，使用中也有可(ke)(ke)能燒(shao)(shao)壞(huai)。特(te)別是用戶(hu)將(jiang)強制(zhi)(zhi)排氣式熱(re)水(shui)(shui)器(qi)安(an)裝在浴室(shi)中時(shi)，由于經常有大量水(shui)(shui)蒸氣從熱(re)水(shui)(shui)器(qi)面板上(shang)的(de)百葉窗進入，電(dian)(dian)源變(bian)(bian)壓(ya)(ya)(ya)器(qi)更加(jia)容易燒(shao)(shao)壞(huai)。

(6)控制(zhi)電路的故(gu)障(zhang) 與電源(yuan)(yuan)有關的控制(zhi)電路部分發生故(gu)障(zhang)時，電源(yuan)(yuan)供(gong)給將不(bu)正(zheng)常，電源(yuan)(yuan)指示燈也將不(bu)亮。

熱水器不管是(shi)(shi)燃(ran)氣的(de)還是(shi)(shi)電(dian)的(de)，電(dian)源指示燈不亮都(dou)會時常發生的(de)，遇到此類問題，請及(ji)時致電(dian)我們(men)(men)的(de)維修中(zhong)心，我們(men)(men)會及(ji)時為(wei)您提供優質的(de)上門(men)檢修服務(wu)。
