除(chu)了 太(tai)陽能(neng) 以(yi)外， 熱(re)水(shui)器(qi) 就(jiu)是現(xian)在(zai)很多(duo)家庭 浴室 中(zhong) 裝修 的不二選擇了，那么(me)(me)(me)我們在(zai)使用(yong)熱(re)水(shui)器(qi)的時候經常(chang)會(hui)遇到忽冷忽熱(re)的問題，這(zhe)個時候經常(chang)是因為燃(ran)(ran)氣(qi)熱(re)水(shui)器(qi)的主(zhu)板是出現(xian)故障(zhang)了，那么(me)(me)(me)故障(zhang)的原因有(you)很多(duo)，我該如何(he)判斷故障(zhang)的原因，現(xian)在(zai)小編(bian)為大(da)(da)家介紹(shao)一下，怎么(me)(me)(me)檢(jian)測年代(dai)燃(ran)(ran)氣(qi)熱(re)水(shui)器(qi)主(zhu)板的故障(zhang)，幫助大(da)(da)家進行故障(zhang)的判別(bie)以(yi)及排除(chu)。

　　怎么檢(jian)測年代燃氣熱水器(qi)主板故障

　　1.先進(jin)行(xing)接”三管(guan)(guan)“并(bing)通(tong)電(dian)試機(ji)(ji)，即接好進(jin) 水管(guan)(guan) 、出(chu)水管(guan)(guan)、氣管(guan)(guan)。通(tong)電(dian)試機(ji)(ji)后發現屏(ping)幕有溫度46數(shu)字(zi)顯示，且數(shu)字(zi)可以(yi)調節但(dan)沒有風機(ji)(ji)運轉的聲音(yin)(yin)也沒有點火(huo)的聲音(yin)(yin)，只有開機(ji)(ji)時的嘀聲而已。

　　2.根據故障最初的現像E4故障代碼顯示，分析故障為：風機或其驅動電路故障。比如：風機故障、霍爾電路故障、啟動 電容 故障、400對不起呼叫不成功驅動電壓故障等等。

　　3.首(shou)先，檢測(ce)電(dian)(dian)腦板輸出(chu)的(de)電(dian)(dian)機(ji)(ji)驅(qu)動(dong)電(dian)(dian)壓，實測(ce)為交流5.04V。此(ci)電(dian)(dian)壓與(yu)標(biao)準的(de)220V相差甚遠(yuan)，所以，從外面散熱(re)孔位置觀(guan)察內(nei)(nei)部線圈沒(mei)有(you)燒蝕的(de)現(xian)像。用(yong)電(dian)(dian)容表測(ce)量啟動(dong)電(dian)(dian)容容量在正常(chang)值范圍內(nei)(nei)，說(shuo)明(ming)(ming)啟動(dong)電(dian)(dian)容沒(mei)有(you)問(wen)題(ti)，接下來干脆用(yong)測(ce)試線單獨測(ce)試風(feng)機(ji)(ji)，實測(ce)風(feng)機(ji)(ji)運(yun)轉正常(chang)。說(shuo)明(ming)(ming)電(dian)(dian)機(ji)(ji)本(ben)身沒(mei)有(you)損壞，故障應該在供電(dian)(dian)電(dian)(dian)路也就是電(dian)(dian)腦板上(shang)。

　　4.為了證(zheng)明確(que)實為電腦板故障，接(jie)著測(ce)量電腦板外圍的負載比(bi)如： 點火器(qi) 、電磁(ci)閥(fa)、水流(liu) 傳(chuan)感(gan)器(qi) 等。

　　先測量點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)，此類機(ji)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)與普通(tong)的(de)液化氣(qi)(qi)燃氣(qi)(qi)熱水器(qi)(qi)(qi)(qi)的(de)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)不(bu)同(tong)，普通(tong)的(de)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)是3V供電(dian)，而這類天燃氣(qi)(qi)熱水器(qi)(qi)(qi)(qi)的(de)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)大部分采用的(de)是12V供電(dian)。將(jiang)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)的(de) 插頭 拔掉，用直流(liu)12V電(dian)源單獨(du)給點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)供電(dian)，聽不(bu)到(dao)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)有打火(huo)(huo)(huo)聲(sheng)，說(shuo)明其已經損(sun)壞。隨即將(jiang)損(sun)壞的(de)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)拆下更換全新的(de)點(dian)(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)(qi)(qi)上機(ji)安(an)裝(zhuang)固定(ding)。
