華帝燃氣熱水器電源指示燈不亮的原因

 華帝燃氣(qi)熱水器電(dian)源指示燈不亮的原因(yin)

(2)電(dian)源(yuan)指示(shi)燈(deng)壞 電(dian)源(yuan)有電(dian)，僅僅電(dian)源(yuan)指示(shi)燈(deng)不亮，此時并不影響熱水(shui)器的(de)使(shi)用。

(3)電(dian)(dian)源(yuan)三眼插(cha)座(zuo)中(zhong)(zhong)的(de)地(di)(di)線(xian)(xian)帶電(dian)(dian) 強排式熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)一(yi)般都用(yong)三芯電(dian)(dian)源(yuan)線(xian)(xian)供電(dian)(dian)，并(bing)且其(qi)中(zhong)(zhong)接地(di)(di)線(xian)(xian)一(yi)般都與熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)外殼（也包括(kuo)燃(ran)燒(shao)器(qi)(qi)及(ji)熱(re)交換器(qi)(qi)）相(xiang) 接零連(lian)(lian)。安裝(zhuang)后，熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)外殼又通過進出水(shui)(shui)(shui)(shui)金屬軟(ruan)管(guan)與自來水(shui)(shui)(shui)(shui)管(guan)相(xiang)連(lian)(lian)。如果電(dian)(dian)源(yuan)三眼插(cha)座(zuo)中(zhong)(zhong)的(de)地(di)(di)線(xian)(xian)帶電(dian)(dian)，則當熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)的(de)電(dian)(dian)源(yuan)插(cha)頭插(cha)入電(dian)(dian)源(yuan)插(cha)座(zuo)時(shi)，電(dian)(dian)源(yuan)地(di)(di)線(xian)(xian)中(zhong)(zhong)的(de)電(dian)(dian)流被(bei)連(lian)(lian)接到自來水(shui)(shui)(shui)(shui)管(guan)而短路。輕者(zhe)將保險(xian)絲燒(shao)斷，嚴(yan)重時(shi)還(huan)將熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)電(dian)(dian)源(yuan)線(xian)(xian)中(zhong)(zhong)的(de)地(di)(di)線(xian)(xian)燒(shao)斷（這時(shi)火(huo)線(xian)(xian)及(ji)零線(xian)(xian)往往還(huan)完(wan)好(hao)）。

(4)電(dian)源(yuan)(yuan)電(dian)壓(ya)曾經發(fa)生過異常（如曾出現過380V的(de)電(dian)壓(ya)） 因一般熱(re)水器的(de)電(dian)源(yuan)(yuan)部分都安(an)裝有壓(ya)敏(min)(min)(min)電(dian)阻（過壓(ya)保護器），外(wai)部電(dian)源(yuan)(yuan)電(dian)壓(ya)過高時(shi)該壓(ya)敏(min)(min)(min)阻將(jiang)燒(shao)壞（詳(xiang)見“關(guan)鍵部件”一章）o由于(yu)壓(ya)敏(min)(min)(min)電(dian)阻燒(shao)壞后其電(dian)阻接近于(yu)零，使電(dian)源(yuan)(yuan)接近于(yu)短路，因此(ci)此(ci)時(shi)熱(re)水器中的(de)電(dian)源(yuan)(yuan)保險(xian)絲(si)也(ye)將(jiang)燒(shao)斷。更換電(dian)源(yuan)(yuan)保險(xian)絲(si)及壓(ya)敏(min)(min)(min)電(dian)阻之前，必(bi)須先排除(chu)外(wai)部電(dian)源(yuan)(yuan)的(de)故障。

(5)電(dian)(dian)源變(bian)壓(ya)器(qi)(qi)(qi)燒壞 電(dian)(dian)源電(dian)(dian)壓(ya)異常可(ke)(ke)燒壞電(dian)(dian)源變(bian)壓(ya)器(qi)(qi)(qi)。另(ling)外，電(dian)(dian)源變(bian)壓(ya)器(qi)(qi)(qi)制作過程中如浸(jin)漆處理(li)不好，防潮性(xing)能(neng)差，使用中也(ye)有(you)可(ke)(ke)能(neng)燒壞。特別(bie)是用戶將強制排氣(qi)(qi)式熱水器(qi)(qi)(qi)安裝在浴室中時，由于(yu)經常有(you)大量水蒸氣(qi)(qi)從熱水器(qi)(qi)(qi)面板(ban)上的百(bai)葉窗進(jin)入，電(dian)(dian)源變(bian)壓(ya)器(qi)(qi)(qi)更加容(rong)易燒壞。

(6)控(kong)制(zhi)電(dian)路的故障 與電(dian)源(yuan)有關的控(kong)制(zhi)電(dian)路部(bu)分(fen)發生故障時(shi)，電(dian)源(yuan)供給將不(bu)正常(chang)，電(dian)源(yuan)指(zhi)示燈也將不(bu)亮(liang)。

熱水器(qi)不管是燃(ran)氣(qi)的(de)還是電的(de)，電源指示燈不亮都會時(shi)常(chang)發生的(de)，遇(yu)到此類問題(ti)，請及(ji)時(shi)致電我們(men)的(de)維修中心，我們(men)會及(ji)時(shi)為您提供優質的(de)上門檢修服務。
