華帝燃氣熱水器電源指示燈不亮的原因

 華帝(di)燃氣熱水器電源(yuan)指示燈不(bu)亮的原因(yin)

(2)電源指(zhi)示燈(deng)壞 電源有電，僅僅電源指(zhi)示燈(deng)不亮，此(ci)時并不影響熱(re)水器的(de)使用(yong)。

(3)電(dian)源(yuan)三眼插(cha)座(zuo)中的地(di)(di)線帶電(dian) 強排(pai)式熱(re)水(shui)器(qi)(qi)一般都用三芯電(dian)源(yuan)線供電(dian)，并且其中接地(di)(di)線一般都與(yu)熱(re)水(shui)器(qi)(qi)外殼（也包括(kuo)燃燒器(qi)(qi)及(ji)熱(re)交換器(qi)(qi)）相 接零連(lian)。安裝后(hou)，熱(re)水(shui)器(qi)(qi)外殼又通過進(jin)出水(shui)金屬軟管與(yu)自(zi)來水(shui)管相連(lian)。如果電(dian)源(yuan)三眼插(cha)座(zuo)中的地(di)(di)線帶電(dian)，則當熱(re)水(shui)器(qi)(qi)的電(dian)源(yuan)插(cha)頭插(cha)入電(dian)源(yuan)插(cha)座(zuo)時，電(dian)源(yuan)地(di)(di)線中的電(dian)流被連(lian)接到自(zi)來水(shui)管而短路。輕者將保險絲(si)燒斷，嚴重(zhong)時還將熱(re)水(shui)器(qi)(qi)電(dian)源(yuan)線中的地(di)(di)線燒斷（這(zhe)時火線及(ji)零線往往還完好）。

(4)電(dian)(dian)源電(dian)(dian)壓曾經發生過(guo)(guo)異(yi)常（如曾出現過(guo)(guo)380V的(de)電(dian)(dian)壓） 因一(yi)般熱(re)水器(qi)的(de)電(dian)(dian)源部(bu)分都(dou)安裝有壓敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)（過(guo)(guo)壓保(bao)護器(qi)），外(wai)部(bu)電(dian)(dian)源電(dian)(dian)壓過(guo)(guo)高(gao)時該(gai)壓敏(min)(min)(min)阻(zu)(zu)將(jiang)燒壞(huai)（詳(xiang)見(jian)“關(guan)鍵部(bu)件”一(yi)章）o由于壓敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)燒壞(huai)后其(qi)電(dian)(dian)阻(zu)(zu)接近于零(ling)，使(shi)電(dian)(dian)源接近于短(duan)路，因此(ci)此(ci)時熱(re)水器(qi)中(zhong)的(de)電(dian)(dian)源保(bao)險絲也將(jiang)燒斷(duan)。更換電(dian)(dian)源保(bao)險絲及壓敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)之(zhi)前，必(bi)須先排除(chu)外(wai)部(bu)電(dian)(dian)源的(de)故障。

(5)電(dian)源(yuan)(yuan)變(bian)壓(ya)(ya)器(qi)燒(shao)壞(huai)(huai) 電(dian)源(yuan)(yuan)電(dian)壓(ya)(ya)異(yi)常(chang)可(ke)燒(shao)壞(huai)(huai)電(dian)源(yuan)(yuan)變(bian)壓(ya)(ya)器(qi)。另外，電(dian)源(yuan)(yuan)變(bian)壓(ya)(ya)器(qi)制作過程中(zhong)(zhong)如浸漆(qi)處理不好，防潮性能差，使用中(zhong)(zhong)也有可(ke)能燒(shao)壞(huai)(huai)。特別(bie)是用戶將強(qiang)制排(pai)氣(qi)式熱水(shui)(shui)器(qi)安裝(zhuang)在(zai)浴(yu)室中(zhong)(zhong)時，由于經常(chang)有大(da)量水(shui)(shui)蒸氣(qi)從熱水(shui)(shui)器(qi)面板(ban)上的百葉窗進入，電(dian)源(yuan)(yuan)變(bian)壓(ya)(ya)器(qi)更加容(rong)易(yi)燒(shao)壞(huai)(huai)。

(6)控制電(dian)路(lu)的故(gu)障(zhang) 與電(dian)源有關(guan)的控制電(dian)路(lu)部分發(fa)生故(gu)障(zhang)時(shi)，電(dian)源供給(gei)將不(bu)正常(chang)，電(dian)源指示燈(deng)也將不(bu)亮。

熱水器不(bu)管是燃氣的還是電的，電源指示燈不(bu)亮都會(hui)時常發生的，遇到此類問(wen)題，請(qing)及(ji)(ji)時致(zhi)電我們的維(wei)修中心，我們會(hui)及(ji)(ji)時為您提(ti)供優質的上門檢修服務。
