華帝燃氣熱水器電源指示燈不亮的原因

 華帝燃氣熱水器電源指示燈不(bu)亮的原(yuan)因

(2)電源指示燈壞 電源有(you)電，僅僅電源指示燈不亮，此時并不影響熱水(shui)器的使用。

(3)電(dian)(dian)(dian)源(yuan)(yuan)三眼插座(zuo)中(zhong)(zhong)的地(di)線(xian)帶電(dian)(dian)(dian) 強排(pai)式(shi)熱(re)(re)水(shui)器一般(ban)都用三芯(xin)電(dian)(dian)(dian)源(yuan)(yuan)線(xian)供電(dian)(dian)(dian)，并(bing)且其中(zhong)(zhong)接地(di)線(xian)一般(ban)都與熱(re)(re)水(shui)器外(wai)殼（也包括燃(ran)燒器及熱(re)(re)交換器）相 接零連(lian)。安裝后，熱(re)(re)水(shui)器外(wai)殼又通(tong)過進出水(shui)金屬軟管與自(zi)來水(shui)管相連(lian)。如果電(dian)(dian)(dian)源(yuan)(yuan)三眼插座(zuo)中(zhong)(zhong)的地(di)線(xian)帶電(dian)(dian)(dian)，則當熱(re)(re)水(shui)器的電(dian)(dian)(dian)源(yuan)(yuan)插頭插入電(dian)(dian)(dian)源(yuan)(yuan)插座(zuo)時(shi)，電(dian)(dian)(dian)源(yuan)(yuan)地(di)線(xian)中(zhong)(zhong)的電(dian)(dian)(dian)流(liu)被連(lian)接到(dao)自(zi)來水(shui)管而短路。輕(qing)者將保險絲燒斷(duan)，嚴(yan)重(zhong)時(shi)還將熱(re)(re)水(shui)器電(dian)(dian)(dian)源(yuan)(yuan)線(xian)中(zhong)(zhong)的地(di)線(xian)燒斷(duan)（這時(shi)火線(xian)及零線(xian)往往還完好(hao)）。

(4)電源電壓(ya)曾(ceng)經發(fa)生(sheng)過(guo)異常（如曾(ceng)出現過(guo)380V的(de)(de)(de)電壓(ya)） 因一(yi)般熱(re)水(shui)器(qi)的(de)(de)(de)電源部(bu)(bu)分都安裝有壓(ya)敏電阻（過(guo)壓(ya)保(bao)護(hu)器(qi)），外部(bu)(bu)電源電壓(ya)過(guo)高時該(gai)壓(ya)敏阻將燒壞(huai)（詳見(jian)“關鍵部(bu)(bu)件(jian)”一(yi)章）o由于(yu)(yu)壓(ya)敏電阻燒壞(huai)后其(qi)電阻接近(jin)于(yu)(yu)零(ling)，使(shi)電源接近(jin)于(yu)(yu)短(duan)路，因此(ci)此(ci)時熱(re)水(shui)器(qi)中的(de)(de)(de)電源保(bao)險絲也(ye)將燒斷。更換電源保(bao)險絲及壓(ya)敏電阻之(zhi)前，必須先(xian)排除外部(bu)(bu)電源的(de)(de)(de)故障。

(5)電(dian)(dian)源(yuan)變壓(ya)器(qi)燒壞(huai)(huai) 電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)異常(chang)可(ke)燒壞(huai)(huai)電(dian)(dian)源(yuan)變壓(ya)器(qi)。另(ling)外(wai)，電(dian)(dian)源(yuan)變壓(ya)器(qi)制作(zuo)過程(cheng)中(zhong)如(ru)浸漆處理不好，防潮性能(neng)差，使(shi)用中(zhong)也有可(ke)能(neng)燒壞(huai)(huai)。特別(bie)是用戶(hu)將(jiang)強制排氣(qi)式(shi)熱水(shui)(shui)器(qi)安裝在浴(yu)室中(zhong)時(shi)，由于(yu)經常(chang)有大量水(shui)(shui)蒸氣(qi)從熱水(shui)(shui)器(qi)面板上的百葉窗進入，電(dian)(dian)源(yuan)變壓(ya)器(qi)更加容易燒壞(huai)(huai)。

(6)控(kong)制電(dian)路的故障 與電(dian)源(yuan)有關的控(kong)制電(dian)路部分發生故障時(shi)，電(dian)源(yuan)供(gong)給將不(bu)正常，電(dian)源(yuan)指示(shi)燈也(ye)將不(bu)亮。

熱水(shui)器不管是(shi)燃氣的(de)還(huan)是(shi)電(dian)的(de)，電(dian)源指示(shi)燈(deng)不亮都(dou)會時(shi)(shi)常發生的(de)，遇到此類問題(ti)，請及時(shi)(shi)致(zhi)電(dian)我們的(de)維修中心，我們會及時(shi)(shi)為您提(ti)供優質的(de)上門檢修服務。
