現在家家戶戶都離不開冰箱，冰箱對我們的生活有非常大的幫助，如果有吃不完的食物或者需要儲存食物都可以存放在冰箱里，以防止食品的變質。這樣既方便又容易。但是由于冰箱夜以繼?地?作，有時難免會出現些故障，出現故障該怎么維修呢？

冰箱構造

維修冰箱，首先我們需要了解冰箱的構造。

家用電冰箱由箱體、制冷系統、溫度控制裝置三部分組成。

箱體

箱體的組成：外殼、內襯、絕熱層、臺面。

箱體的基本作用是絕熱，絕熱性能的優劣直接關系到箱體的保溫性能。

箱體的隔熱功能主要是從以下幾個方面來實現的：

1、外殼與內襯之間填充絕熱材料。

2、箱門裝有磁性密封條防止冷氣外漏和熱空氣侵入。

3、箱頂的頂板下面墊有高密度聚苯乙烯泡沫板，起隔熱作用。

制冷系統

制冷系統組成：壓縮機、冷凝器、蒸發器、毛細管。

制冷系統自成一個封閉的循環系統。其中蒸發器安裝在電冰箱內部的上方，其他部件安裝在電冰箱的背面。

工作原理：系統里充灌了一種叫“氟里12(CF2Cl2，國際符號R12)”的物質作為制冷劑（氟利昂類包括氟利昂12和氟利昂11等等是一般傳統的制冷劑，現在更多的是新興的無氟制冷劑如R600a、R404a等，不過制冷原理是一樣的）。氟里昂12在蒸發器里由低壓液體汽化為氣體，吸收冰箱內的熱量，使箱內溫度降低。變成氣態的氟里昂12被壓縮機吸入，靠壓縮機把它壓縮成高溫高壓的氣體，再排入冷凝器。在冷凝器中氣態的氟里昂12不斷向周圍空間放熱，逐步液化成液體。這些高壓液體必須流經毛細管，節流降壓才能緩慢流入蒸發器，維持在蒸發器里繼續不斷地汽化，吸熱降溫。就這樣，冰箱利用電能做功，借助制冷劑的物態變化，把箱內蒸發器周圍的熱量搬送到箱后冷凝器里去放出，如此周而復始不斷地循環，以達到制冷目的。

內部汽化吸熱?→?外部液化放熱→?箱內溫度降低

溫度控制裝置

冰箱的溫度控制裝置叫溫度控制器。它的主要作用是當箱內溫度過高時接通壓縮機，使制冷系統工作，從而使箱溫降下來，當箱溫降至要求的溫度時，使壓縮機斷電。

故障檢測方法

冰箱故障的檢查方法一般可分為問、看、聽、摸、測試等。通過檢查，綜合分析判斷，逐漸縮小故障范圍，找出故障點。

問

首先問明冰箱的使用情況、故障現象及使用年限，特別是舊機器，要了解機器的故障史及以前維修后的使用情況，對曾維修過制冷系統的機器，要多留意冰堵、臟堵、混入空氣、冷凍油是否變質等故障。

看

1、首先看蒸發器結霜的情況，在壓縮機運轉的情況下，如果出現蒸發器表面無霜、結不滿霜或結霜不實等情況，都說明制冷系統工作不正常。

2、冰箱冷凍室結冰，說明溫控器溫差過大，停機時間過長等因素造成的，直冷式雙門冰箱的冷藏室蒸發器總是結滿霜而無結霜、化霜交替變化，說明溫控器發生故障。

3、檢查制冷系統中管路的各個焊接處及蒸發器表面，看是否有滲漏的痕跡，凡滲漏處都會有油漬。

4、查看壓縮機回氣管是否結霜，如結霜，則說明制冷劑沖入量過多，對于間冷式冰箱，如壓縮機回氣管結霜，還應考慮是否由于風扇不轉而引起。遇到這種情況，可以打開箱門，按下門框按鈕，查看風扇是否旋轉。

5、查看箱門是否有縫隙。如果箱門有縫隙，則冰箱保溫性能差，導致壓縮機開機時間長，停機時間短，而且冰箱結霜多。

聽

1、接通冰箱電源，如果聽到啟動器“叭嗒”一聲，壓縮機在0.2秒至0.5秒內啟動，隨后壓縮機發出輕微而且有節奏的運轉聲，說明壓縮機啟動正常。如壓縮機發出沉悶的“嗡嗡”聲，而后連續聽到“叭嗒”的啟動器觸點斷開、吸合的聲音，有時還帶有壓縮機的振動聲，最后可以聽到熱保護器“叭”的一聲響，隨后切斷壓縮機電源。此故障可以考慮以下原因：

a、電源電壓低，壓縮機卡缸、抱缸軸。

b、電動機掃堂。

c、電動機繞組短路。

d、電動機啟動繞組開路。

e、氣路系統管路堵塞。

f、啟動繼電器故障等。使用排除法，確定故障原因。

2、壓縮機運轉時，機殼內有明顯的噴氣聲，說明壓縮機排氣緩沖管斷裂漏氣。若壓縮機機殼有破裂聲，說明壓縮機高、低壓閥片破裂、漏氣。壓縮機剛停機時，聽到機殼內有明顯的跑氣聲音，說明壓縮機閥板的高低壓紙墊被擊穿、排氣減震管泄漏、閥片磨損或閥片、閥口處積碳。壓縮機運轉時，如果機殼發出“當當”的撞擊聲，說明壓縮機內支撐彈簧斷裂或疲勞變形。

3、高壓液態制冷劑通過毛細管進入蒸發器，迅速蒸發沸騰，同時發出“嘶嘶”的氣流聲音，并時常伴流水的聲音，屬于正常現象。如果聽到蒸發器內有“嘰嘰”聲，或者有斷斷續續的憋氣聲，故障通常為臟堵、油堵或者冰堵。周期性較長的斷續噴氣聲一般為冰堵。若蒸發器內只有氣流聲，而且不結霜，說明系統內制冷劑基本漏完。

4、冰箱有時發出斷斷續續的噪音，往往是由于冰箱支腳落地不穩，制冷系統管路相互碰撞以及壓縮機與箱體底座螺絲松動等原因引起共振造成的。

摸

冰箱正常運行時，制冷系統各個部分的溫度通過觸摸，可以對制冷系統狀況有個大致的判斷。(制冷系統各個部分的溫度還受環境溫度的影響，環境溫度升高時，冷凝器、過濾器、回氣管和壓縮機的溫度明顯升高，反之，上述部分的溫度明顯降低。)

1、壓縮機運轉時，觸摸冷凝器上部，應很熱(大于55℃)。如不熱，可能是制冷系統漏氣、堵塞或壓縮機沒有排氣壓力等故障。

2、正常時，觸摸干燥過濾器應有熱的感覺(約55℃)。如制冷系統過臟，會造成干燥過濾器溫度升高，對于剛剛維修過的冰箱，如果干燥過濾器溫度過高，一般為毛細管阻流偏大，制冷劑充入量過大。

3、壓縮機正常工作時，觸摸壓縮機回氣管，應沒有熱感(接近于環境溫度)。如果溫度高，說明系統少制冷劑，管路微堵或系統中混入空氣。如果感覺到冷或者有露水甚至結霜時，說明制冷劑充入量過多。

4、壓縮機機殼的溫度一般在70℃以下。即使在夏季，冰箱首次開機時，壓縮機經過連續長時間的工作，機殼溫度也不超過85℃。

5、如果蒸發器上結的霜用手一摸就脫落(稱為虛霜)，并且壓縮機回氣管結滿霜，說明充入的制冷劑過多或新換的毛細管過粗、過短。

6、用手觸摸蒸發器表面，如果發現蒸發器結不滿霜，說明系統制冷劑不足或毛細管半堵塞。

測試

通過測量冰箱的溫度、壓力、開機與停機比、運轉電流以及壓縮機的絕緣電阻和直流電阻等，對冰箱進行檢查。

1、測溫度

用電機溫度計測量電冰箱的溫度。電冰箱的溫度按國家標準吸氣溫度為三十二攝氏度，蒸發溫度為負二十三攝氏度一下，排氣溫度為五十五攝氏度左右，過冷溫度為三十二攝氏度左右。

1、冰箱靠近墻面放置會導致冰箱發燙，也不能在冰箱的周圍覆蓋東西，這樣都會阻礙冰箱散熱，使溫度上升，應該保持冰箱有足夠的空間散熱。

2、在使用冰箱的時候不要打開頻繁，頻繁的打開冰箱會讓里的溫度升高，加大冰箱的工作量，冰箱長期處于運轉狀態就會使溫度更高的。這時要減少開冰箱的次數。

3、停用之后特別是在夏季溫度很高的時候，冰箱要達到設定的制冷溫度會需要很長時間，長時間的運轉就會使冰箱的溫度升高，冰箱一旦使用最好不要停用了。

2、測壓力

冰箱的正常壓力值在0.03~0.08mpa。

a、吸氣壓力過高，通常由：制冷劑充入過多、新換毛細管過短、壓縮機性能無法維持正常運行的原因引起。

b、出現吸氣壓力為負壓時，通常由：制冷劑不足、系統內有堵塞現象、新換毛細管太細、太長。

2、測量冰箱的開機與停機之比

冰箱的開機與停機之比與它的制冷系統、保溫性能、溫控器性能、調節位置、環境溫度、電路系統、冰箱內食品的多少以及開門次數等有著直接的關系。

3、測量工作電流

1、如果工作電流大于額定電流，說明制冷劑充入量過多，制冷系統微堵、壓縮機局部短路。

2、如果工作電流小于額定電流，說明制冷系統有泄漏或系統完全堵塞。

3、測量絕緣電阻和直流電阻：(對于匝間短路不嚴重或匝間絕緣不良的電機繞組，用電阻測量方法很難分辨電機故障，因此只能采用測量工作電流的方法來判斷)。

缺少制冷劑，或蒸發器內有沉積的冷凍機油，導致壓縮機效率降低。

冰箱故障分類

電冰箱的故障可分為電氣系統故障和制冷系統故障兩大類。

電氣系統故障分析

電氣系統主要包括溫控部分和壓縮機電動機控制部分。由此而引起的故障現象是電冰箱接通電源后壓縮機不起動和接通電源后壓縮機運轉不停。

1、首先用萬用表歐姆擋測量冰箱電源插頭的阻值。

壓縮機的三個接線端子以及與起動器之間的接線情況如圖所示：C——公共端、M——運行端、S——起動端。

各繞組間直流電阻值如下：運行繞組C、M兩端約10.5Ω；起動繞組C、S兩端約22Ω；而運行和起動繞組阻值的和即S、M端的阻值約為32.5Ω。正常時電路所有的開關觸點都接通，對于重錘起動器式的冰箱，因重錘式起動器觸點未通電而未接通，回路阻值為壓縮機運行繞組的阻值，一般為10—20Ω左右，對于PTC起動冰箱，回路的直流電阻為起動器20Ω阻值與起動繞組串聯后再與運行繞組并聯，所以其電阻略小于壓縮機運行繞組的阻值。

通過測得的阻值來判斷電路的工作狀態，阻值偏大時，要檢查溫度控制器、過載保護器、壓縮機電動機以及線路和觸點接觸情況，阻值偏小時一般是短路，主要檢查壓縮機電動機及其線路。

2、要進一步判斷還要對冰箱通電檢查。

通電前先檢查溫控器開關是否正常。如溫度控制器裝在電冰箱的冷藏室內，當放置的環境溫度低于設計溫度時不會起動運轉，故有的冰箱設計了冬季補償開關，補償開關打開后則溫度控制器感溫管附近的加熱器開始加熱，強制升溫使壓縮機運轉，目的是犧牲冷藏室的正常溫度而保證冷凍室的溫度。

如果溫控器內的開關都正常，而通電后壓縮機不起動，可用一根導線短接重錘式起動器的兩個靜觸點，注意導線短接時間不要太長，以不超過2s為宜，時間長將會使起動繞組燒壞。如果短接后冰箱能起動，說明起動器有故障，重錘式起動器長期起動易使觸點燒壞，測量時拆下起動器，用萬用表歐姆RX1擋，將兩表筆插入接線柱插孔內。起動器正著放時相當于正常運轉狀態，即未接通，萬用表測量阻值為無窮大；將起動器倒過來時相當于起動狀態，萬用表指示為0Ω，則說明起動器是好的。

如果用導線短接后仍不能起動，就需要檢查保護器。可用短接法檢查保護器，將保護器的兩個接線銅片短接起來，如果冰箱能夠起動運轉，說明保護器有故障，可能是電熱絲燒斷或碟形雙金屬片受阻不能下翻，如果冰箱仍不能起動，則是壓縮機或起動器有問題。檢查時，把起動器和保護器拆下，露出電動機的三根接線柱。測每兩個接線柱之間的電阻值，如正常，說明電動機繞組沒有故障。如不正常，不要急于拆開壓縮機，可以采用直接接通電源的方法進行檢查。具體辦法是：用帶有電源插頭的兩根電源線接在M、C接線柱上，也就是運行繞組上，再用螺釘旋具作為導線同時碰觸M和S端，然后把插頭插入電源插座，如果電動機和壓縮機沒有故障，就會起動。起動2s左右，就要把螺釘旋具移開，電動機進入正常運轉。如果檢查壓縮機能起動運轉，說明電動機沒有故障，故障發生在電動機外部，可能是外引線折斷或接線柱接觸不良，也可能是環境溫度過低等。否則為壓縮機故障。

制冷系統故障分析

電冰箱不制冷

電冰箱運轉不停，但是不制冷，冷凝器不熱，蒸發器不涼。這種故障一般出現在制冷系統。

可能原因是制冷劑泄漏，或者冰堵、臟堵，或是壓縮機有故障。由于制冷系統是封閉的，所以可通過觀察管路表面有無油污、用手觸摸各部分的溫度、耳聽運行聲音來檢查。

1、檢查管路表面是否有油污

仔細檢查冷凝器、過濾器、毛細管、蒸發器；吸氣管、壓縮機外殼及管路結合處。如果發現有油污，說明制冷劑泄漏。這時可切開壓縮機的工藝管。如果有少量的制冷劑噴出，就進一步證明是制冷劑泄漏。

如果沒有油污，則需要進一步檢查壓縮機的溫度。

2、檢查壓縮機的溫度

用手摸壓縮機，如果壓縮機的溫度不太高，和運轉時差不多，說明管路暢通，沒有堵塞現象，而可能是高壓緩沖管破裂、活塞穿孔、排氣閥同吸氣閥短路等。這時可切開高壓排氣管，排出制冷劑。

3、檢查壓縮機開機時的情況

切斷電冰箱的電源，打開箱門；使制冷系統各個部件恢復到室溫。然后接通電源，電冰箱啟動運轉。如果開始時蒸發器結霜較好，冷凝器發熱，低壓吸氣管發涼；由冰箱上部能聽到氣流聲和水流聲，但過一會兒，蒸發器結霜融化，只在毛細管同蒸發器結合部位結有少量霜；冷凝器不熱，低壓吸氣管不涼，用耳朵貼近電冰箱上部聽不到聲音，說明出現了冰堵。這時如果用熱毛巾敷在毛細管同蒸發器的結合處，又能重新制冷，則進一步證實是冰堵。

如果開機的時候不見蒸發器結霜，冷凝器不熱，低壓氣管不涼，用耳朵貼近電冰箱上部聽不到聲音，則可以初步認為發生了臟堵。這時，可以切斷高壓排氣管，排出制冷劑，用手指按住排氣管，啟動壓縮機，如果手指感到有較大的壓力，說明管路發生臟堵。

電冰箱制冷效果差

電冰箱運轉不停，但箱內溫度達不到要求，制冷效果差。這可能是由于使用不當或箱門關閉不嚴造成的。也可能是制冷系統故障引起的。一般應先檢查使用情況和箱門情況，再檢查制冷系統。

1、檢查使用情況

首先要了解環境溫度。如果高于43℃，制冷效果差一些是正常的。如果環境溫度不高，要打開箱門檢查。如果箱內食品太多，特別是放入了溫度高的食品，食品釋放出大量的熱量；或者打開箱門次數太多，外界熱空氣不斷進人箱內，或者未及時化霜等，所有這些都會使電冰箱長時間運轉不停，制冷效果差。

2、檢查箱門

電冰箱箱門關閉不嚴，熱空氣會從縫隙處不斷進入箱內。這可能是磁性門封條失去磁性、老化變形，或是箱門翹曲造成的。

3、檢查制冷系統

如果使用情況正常，箱門又能關閉嚴密，那么制冷效果差的故障就出在制冷系統。由于制冷系統仍能工作，因此，可能是制冷劑部分泄漏、部分冰堵或部分臟堵，也可能是壓縮機內部故障。

檢查的順序是首先觀察管路表面有無油污。如果有油污，說明制冷劑部分泄漏，這時可以切開工藝管，灌入適量的氟里昂制冷劑，再次啟動運轉。如果運轉正常，證明是制冷劑部分泄漏。如果管路表面沒有油污，可檢查開機時的情況。如果開機時制冷正常，蒸發器結霜良好，在電冰箱上部能聽到氣流聲和水流聲，但過了一會兒制冷效果變差，只能聽到微弱的氣流聲和流水聲，說明是部分冰堵。

如果開機時制冷效果就差，用耳朵貼近冰箱上部只能聽到微弱的氣流聲和水流聲，這可能是臟堵或壓縮機內部故障，需要進一步檢查。這時，可切開工藝管，灌入適量的氟里昂制冷劑，并接入氣壓表，啟動壓縮機。如果氣壓表所示氣壓下降到正常值（0.06～0.08MPa）以下，說明壓縮機內部沒有故障，只是管路有部分臟堵。如果氣壓下降到正常值以上，說明壓縮機性能下降，嚴重時需要拆開壓縮機詳細檢查和修理。

如果制冷系統混入空氣，或者制冷劑充加過多或不足，都可能影響制冷效果。

制冷系統中充加過多的制冷劑，會使過多的制冷劑在蒸發器內不能很好蒸發，液體制冷劑返回壓縮機中，這樣壓縮機的吸氣量減少，制冷系統低壓端壓力升高，又影響蒸發器內制冷劑的蒸發量；造成制冷能力下降。同時，過多的制冷劑會占去冷凝器的一部分容積，減少散熱面積，使冷凝器的冷卻效率降低，吸氣壓力和蒸發溫度也相應提高，吸氣管出現結霜現象。遇到這種情況，必須及時將多余的制冷劑排出制冷系統，否則不但不能提高降溫效果，反而使壓縮機有液擊沖缸的危險。

制冷系統充加的制冷劑過少時，會使蒸發器的蒸發表面積得不到充分利用，制冷量降低，蒸發器表面部分結霜，吸氣管溫度偏高。遇到這種情況，可以補充適量的制冷劑。

冰箱的保養

定期適當保養可以延長冰箱的使用壽命。保養冰箱前務必拔下電源插頭。

1、經常清理冰箱背面或底部冷凝器和壓縮機上的灰塵。可使用吸塵器或毛刷除塵。注意不要用濕布去擦冷藏器和壓縮機上灰塵。

2、冰箱長期停用時，應先切斷電源，取出箱內一切食品，將箱內外清理干凈，敞開箱門數日，使箱內充分干燥并散掉冰箱內的異味。

3、檢查排水管。如果排水管堵塞，水就會漏到冰箱內。要用鐵絲捅一捅排水管，除去積在排水管上的東西。

4、不要忽略門封膠條的清洗，將漂白劑用10倍的水稀釋后用牙刷蘸濕清洗，最后用水將漂白劑沖去。膠條臟污易老化，會影響冰箱的密封性，增加耗電量。

5、檢查振動、噪音以及壓縮機的溫度。運行中摸壓縮機外殼，不應有明顯的振動感，白天不應聽到壓縮機明顯啟動的聲音。

6、注意檢查電源線上是否有裂縫，防止漏電。

7、用溫水或中性洗滌劑將冰箱內外清洗并擦干，敞開冰箱門通風干燥一天。

清潔冰箱外殼最好每天進行，用微濕柔軟的布每天擦拭冰箱的外殼和拉手。清理內膽前先切斷電源，把冰箱冷藏室內的食物拿出來。軟布蘸上清水或食具洗潔精，輕輕擦洗，然后蘸清水將洗潔精拭去。拆下箱內附件，用清水或洗潔精清洗。清潔冰箱的“開關”、“照明燈”和“溫控器”等設施時，請把抹布或海綿擰得干一些。內壁做完清潔后，可用軟布蘸取甘油(醫用開塞露)擦一遍冰箱內壁，下次擦的時候會更容易。用酒精浸過的布清潔擦拭密封條。如果手邊沒有酒精，用1：1醋水擦拭密封條，消毒效果很好。用吸塵器或軟毛刷清理冰箱背面的通風柵，不要用濕布，以免生銹。清潔完畢，插上電源，檢查溫度控制器是否設定在正確位置。
