style="font-size:16px;">有些家用電器出現的故障很怪，常常是使用一開始非常好，但過不了多久，少則幾分鐘，多則一二個小時出現毛病。這往往是由于機內個別元器件的熱穩(wěn)定性較差所引起的。因為這種故障本身的不固定性，在修理的野外，只要一打開機箱，由于冷空氣迅速涌入，家用電器就能很快恢復正常工作。這種現象給修理工作帶來了很多的麻煩。溫度法就是用家用電器內部元件溫度特性而采用的一種有效方法。在具體做法上則分為兩類，加溫法和降溫法。加溫方法在修理過程中，通常要根據自己的經驗和故障現象的特征，華凌家電維修上門，初步對故障部位做大致的判斷。加溫法便是利用電烙鐵或電燈泡等發(fā)熱元件烘烤可疑部位的元器件，華凌家電維修上門，如利用20w燒熱了的電烙鐵頭距可疑元件1cm左右進行烘烤，其目的是進行局部加熱。如烘烤到某一元件時，華凌家電維修上門，故障現象立即再現，就</span><span

style="font-size:16px;">對采暖系統(tǒng)進行檢查維修。給膨脹水箱進行充氣增壓或更換容積大的膨脹水箱。壁掛爐的維修頻率和維修成本的高低是判斷“是修是換”的重要依據。壁掛爐屬于耐用型的采暖設備，在歐洲，燃氣壁掛爐使用15年以上的案例十分普遍，歐盟對燃氣壁掛爐產品實行強制規(guī)定，必須進行每年一次年檢和保養(yǎng)，在這個前提下，壁掛爐的使用壽命沒有限制。在我國壁掛爐實際的使用年限則參差不齊。一般情況下，國內大品牌的壁掛爐在正確使用、正常維護的情況下能使用10年以上。但近年來，隨著國家“煤改氣”政策的快速推進，國內壁掛爐行業(yè)發(fā)展迅猛，市場上涌現了不少技術與品控均較低的小品牌壁掛爐，這些靠低價搶占市場的壁掛爐產品在質量上良莠不齊，維修和使用成本都很高。</span>

style="font-size:16px;">電阻法是檢修故障的基本的方法之一。一般而言，電阻法有"在線"電阻測量和"脫焊"電阻測量兩種方法。"在線"電阻測量，由于被測元器件接在整個電路中，所以萬用表所測得的阻值受到其它并聯支路的影響，在分析測試結果時應給予考慮，以免誤判。正常所測的阻值會比元器件的實標標注阻值相等或小，不可能存在大于實標標注阻值，若是，則所測的元器件存在故障。"脫焊"電阻測量，由于被測元器件</span><span style="font-size:16px;">一端或將整個元器件從印刷電路板上脫焊下來，再用萬用表電阻的一種方法，這種方法操作起來較煩，但測量的結果卻準確、可靠。（1）開關件檢測各種電器中的開關組件</span><span style="font-size:16px;">很多，測量它們的接觸電阻和斷開電阻是判斷開關組件質量好壞是**常用的手段。在線電阻測量開關的接觸電阻應小于Ω，否則為接觸不良。斷開電阻一般應大于幾千歐為正常。</span> </p><p> <span
