2023-08-26 15:55:52维修常识1

<h2>一、磨床的维修经验？</h2>您好，我是专业维修无心磨床的，漏油，一般是回油孔杜塞了，或者主轴间隙太大，，国产机是没有油封的，是铜环圈<h2>二、电工维修经验技巧？</h2>一、先动口再动手针对那些出现问题故障的电气设备，我们不要一上来就要动手对它进行拆卸维修，而是应该向相关人员询问该设备的故障情况以及出现故障的经过。在对设备的故障情况有了一定的了解之后，再着手进行维修。当然，在对设备进行拆卸之前，我们要对设备本身的零部件情况有较为熟悉的把握，按照设备组装图拆卸。若没有组装图的话，我们应该边画草图边拆卸，而且要记得标上记号。二、先外部后内部要先观察设备外部有没有比较明显的损坏痕迹，再了解一下该设备以往有没有维修过以及使用年限是多久等，接着再对它的内部进行检查维修。只有确定了没有外部故障之后，才能对其内部进行检查维修，要不然一开始就将设备拆卸或许会致使设备越修越坏。三、先机械后电气当我们在对设备进行机械检查后，若发现无故障，那我们就再对它的电气方面进行检查，这时，我们可以利用一些检测仪对它进行故障查找和定位。四、先静态后动态在仪器还没有接通电的情况下，可以对设备的接触器、按钮、以及保险丝等功能的好坏进行一个判断通电试验，听其声、测参数、判断故障，最后进行维修。五、先清洁后维修有很多的电气设备是由于污垢以及灰尘引起的故障，当对设备进行清洁之后，就会正常运作。所以我们在维修的时候可以先对很脏的设备进行接线点、接触点的清洁，检查这些控制键到底有没有失灵。六、先电源后设备经过很多电工的经验总结发现，有许多的电源故障是占比很高的，因此，我们在维修设备时先检修电源常常能达到很好的效果，事半功倍。七、先普遍后特殊因装配配件质量或其他设备故障而引起的故障，一般占常见故障的50%左右。电气设备的特殊故障多为软故障，要靠经验和仪表来测量和维修。八、先外围后内部当我们已经发现设备的一些电气部件出现故障的时候，不能着急的将其更换掉，而是应该对外围部件进行检查后若发现能正常工作时，方可考虑更换。九、先直流后交流在进行设备维修的时候，应对直流回路静态工作点进行检查，然后再检查交流回路的动态龚总点。十、先故障后调试有的设备是调试有问题，并且也出现的设备故障，这是我们应该先将故障排除掉，然后再对设备进行调试，但是，值得注意的是，调试应该是在电气线路速的前提下进行。<h2>三、创维冰箱维修？</h2>创维电冰箱修理—维修限温开关，只有无霜冰箱和无霜冷冻箱配置了限温开关。它的功能是防止除霜的加热元件超过预定温度。如果冰箱的冷冻室里大量结霜，则可能是限温开关出现了问题。不过，其他部件如蒸发器风扇、除霜定时器和除霜加热器也可能导致同样的问题。请按以下的详细说明检查这些部件是否出现了故障。如果这些部件的工作运行状态都正常，则问题很可能出在限温开关上。不要尝试自行维修限温开关，而应当打电话请专业维修人员来更换。　　电冰箱修理—清洁排水孔　　排水孔沿冰箱的冷藏室和冷冻室的底部分布。这些孔可能会被碎屑或冰堵塞，从而在冰箱化霜时出现排水出不畅的问题。请使用一小节恰能塞入孔中的电线来进行清洁。不要使用牙签，因为木料可能会折断在孔中，将其堵住。某些冰箱的排水孔位于蒸发器旋管上的除霜加热器附近，清洁这种类型的冰箱需要大量的拆卸工作。如果您的冰箱或冷冻箱恰好是这种类型，那最好打电话请专业维修人员来清洁。某些冷冻室中的排水装置位于其下方，呈鞋拔形状。通常可以拧下这种排水装置的螺钉，然后对排水区进行清洁。　　电冰箱修理—维修排水管和排水盘　　冷凝器的风扇位于冰箱的底部下方。在化霜期间，水可以通过一根细管排到排水盘中并自然蒸发。某些冰箱的排水管材料是橡胶而不是金属制品。这种类型的软管可能会开裂并导致泄漏。检查软管，如果出现了损坏，请将其更换为一根同种类型的新软管。如果您发现地板上有水，则可能是支架上的排水盘倾斜了，也可能是排水盘有裂缝或生锈了。为了消除这种现象，请重新校准排水盘的位置，或换成一个新的排水盘。　　电冰箱修理—维修冷凝器风扇　　冷凝器风扇位于冰箱下方。如果风扇出现故障，冰箱或冷冻箱将无法正常制冷，或者会持续运行，或者根本不运行。请用一只设定为RX1档的万用表来检测风扇。断开连到风扇马达上的电线，将万用表的两个探针分别夹在马达的两个接线端上。如果仪表的读数在50到200欧姆之间，则说明马达能够正常工作;如果读数高于200欧姆，则说明马达出现了故障，应予以更换。当您维修风扇马达时，请确保风扇叶片是干净的，没有受到任何阻碍。如果叶片弯曲，请用钳子小心地将它们弄直。<h2>四、海信冰箱维修？</h2>首先说明一点这种情况冰箱的压缩机将很快损坏{因为非正常使用} 跟室内温度没关系，如果真是你说的这种情况，那肯定是温控器的问题，温控器又有两种可能，一种是温控器损坏触点跳不开，造成压缩机工作不停机{不停机很好判断，嗡嗡24小时都听到}，另一种温控器调整不合适，调太高了。也导致长时间制冷不停。建议先断电化霜完后再通电，看一下使用说明书调整温控器。如果还不行那得报修了注：如果是温控器调整不当，虽然是免费保修期之内，维修店会收一定上门费。<h2>五、冰箱维修前景？</h2>前景还是很好的，关键要看怎么干。目前冰箱已经是家家户户都有的家用电器了，且冰柜的市场容量也很大，这类产品的维修量会比较大，冰箱厂家所提供的产品保修年限又比较短，所以维修这类产品的前景较好。不过这需要自己的队伍专业能力强，处理事情能多为用户着想，需要慢慢积累人气；如果维修中间掺杂太多的坑蒙拐骗，就不会有好的前景。 <h2>六、海尔冰箱维修？</h2>1、不制冷（1）当发现冰箱不制冷，可检查冰箱电源插头是否插在电源插座上，电源插座是否有电，电源断路器是否断开，进行逐个排查，若是，需要对应改正。（2）检查冷藏室门灯是否亮，可确定冰箱是否接通电源；若没有，检查原因，最后接通电源。（3）看温控器是否在工作的档位，温控器有停机档（0档），放在停机档，压缩机是不会工作的；若情况相反，直接说明故障，需专业认识来维修。2、制冷不良（1）当冰箱制冷效果不好时，需要检查温控器档位是否调得太低，若是，可稍微的调试一下，直到合适的位置。（2）检查食品是否存放过多、或放入了过热食品，应该放入冷却后的食物，里面的食物要有一定的缝隙，不过过于紧密。（3）是否频繁开门或门封不严，若是后者，会将手都放在附近，看是否有冷气冒出来。（4）子晴天，看是否被日光直射、或冰箱附近有热源，若是，应该移动位置或者加以更改。（5）检查周围通风情况，一定要流通，不仅可散热，还可以增加消除异味，保持干燥性。（6）检查环境温度是否过低，且温度补偿开关没有打开。3、冰箱有响声启动不了（1）在正常环境温度情况下，就是15-38℃，冰箱启动时，如果压缩机发出“嗡嗡”声，在半分钟左右停止工作，应该是电源电压太低（低于187V），造成的压缩机无法启动。（2）如果压缩机发出“恩恩”声，随即听到“啪嗒”声，那就是电源电压太高（高于242V）、或压缩机连续工作时间太长造成的；当电源电压恢复正常、或压缩机外壳温度降低后，冰箱就不能正常工作等，遇到这样的情况，只能想办法稳定电压，可和当地电工或者相关部门反映。4、冷藏室积水或有水溢出冷藏室排水孔堵塞，造成冷凝水不能顺利排出，这是一个常见现象，可用一定柔韧性的工具进行疏通就好。5、冷藏室后背部结冰<h2>七、冰箱维修技巧？</h2>清洁冰箱：定期清洁冰箱可以保持其良好的工作状态。使用温和的肥皂水和柔软的布擦拭内部和外部表面，并清洗门密封条。检查电源线：确保电源线没有损坏或破裂，并且插头牢固地插入插座。检查温度控制器：如果冰箱无法达到所需的温度，可能是温度控制器故障。检查温度控制器是否正确设置，并尝试将其调整为适当的温度。检查冷却系统：如果冰箱制冷不良，可能是冷却系统出现问题。检查冷却系统是否有漏水或堵塞，并清理冷凝器和排水管道。更换损坏的零件：如果冰箱出现故障，可能需要更换某些零件。例如，如果冰箱门密封条破损，需要更换密封条。如果压缩机故障，需要更换压缩机。注意保养：定期进行冰箱保养可以延长其寿命。例如，定期清洁冰箱内部和外部表面，并确保门密封条处于良好状态。如果您不确定如何进行冰箱维修，请咨询专业技术人员的建议。<h2>八、车载冰箱，维修？</h2>首先必须说明的是，买东西，还是大厂家大品牌的好，尤其是这种电器类的产品。半导体冰箱不制冷可能的原因1、工作电压过低。2、散热不良：风扇不转，可能风扇马达出现问题，（你的情况显然不是这个原因）通风孔不畅，可改变放置位置，清理散热器的灰尘。3、制冷效果差，与使用方法有关。将常温食品或饮料放入冷热箱中，但是在规定时间内没有达到理想的制冷效果，在检测后再放入冷热箱中测量保温效果（箱体内温度在插电后能够保持比常温低于15—20℃都属于正常）。如果制冷效果仍不理想，应查看是否制冷器出了问题。<h2>九、lg冰箱维修？</h2>打开冰箱门。如果内灯能亮，说明冰箱有电；如果灯没有亮起，首先检查总电源，然后检查冰箱的保险丝，最后检查恒温器的触点，并根据相应的问题修复总电源.更换保险丝和温控器触点。<h2>十、冰箱维修教程？</h2>现在家家户户都离不开冰箱，冰箱对我们的生活有非常大的帮助，如果有吃不完的食物或者需要储存食物都可以存放在冰箱里，以防止食品的变质。这样既方便又容易。但是由于冰箱夜以继⽇地⼯作，有时难免会出现些故障，出现故障该怎么维修呢？冰箱构造维修冰箱，首先我们需要了解冰箱的构造。家用电冰箱由箱体、制冷系统、温度控制装置三部分组成。箱体箱体的组成：外壳、内衬、绝热层、台面。箱体的基本作用是绝热，绝热性能的优劣直接关系到箱体的保温性能。箱体的隔热功能主要是从以下几个方面来实现的：1、外壳与内衬之间填充绝热材料。2、箱门装有磁性密封条防止冷气外漏和热空气侵入。3、箱顶的顶板下面垫有高密度聚苯乙烯泡沫板，起隔热作用。制冷系统制冷系统组成：压缩机、冷凝器、蒸发器、毛细管。制冷系统自成一个封闭的循环系统。其中蒸发器安装在电冰箱内部的上方，其他部件安装在电冰箱的背面。工作原理：系统里充灌了一种叫“氟里12(CF2Cl2，国际符号R12)”的物质作为制冷剂（氟利昂类包括氟利昂12和氟利昂11等等是一般传统的制冷剂，现在更多的是新兴的无氟制冷剂如R600a、R404a等，不过制冷原理是一样的）。氟里昂12在蒸发器里由低压液体汽化为气体，吸收冰箱内的热量，使箱内温度降低。变成气态的氟里昂12被压缩机吸入，靠压缩机把它压缩成高温高压的气体，再排入冷凝器。在冷凝器中气态的氟里昂12不断向周围空间放热，逐步液化成液体。这些高压液体必须流经毛细管，节流降压才能缓慢流入蒸发器，维持在蒸发器里继续不断地汽化，吸热降温。就这样，冰箱利用电能做功，借助制冷剂的物态变化，把箱内蒸发器周围的热量搬送到箱后冷凝器里去放出，如此周而复始不断地循环，以达到制冷目的。内部汽化吸热 → 外部液化放热→ 箱内温度降低温度控制装置冰箱的温度控制装置叫温度控制器。它的主要作用是当箱内温度过高时接通压缩机，使制冷系统工作，从而使箱温降下来，当箱温降至要求的温度时，使压缩机断电。故障检测方法冰箱故障的检查方法一般可分为问、看、听、摸、测试等。通过检查，综合分析判断，逐渐缩小故障范围，找出故障点。问首先问明冰箱的使用情况、故障现象及使用年限，特别是旧机器，要了解机器的故障史及以前维修后的使用情况，对曾维修过制冷系统的机器，要多留意冰堵、脏堵、混入空气、冷冻油是否变质等故障。看1、首先看蒸发器结霜的情况，在压缩机运转的情况下，如果出现蒸发器表面无霜、结不满霜或结霜不实等情况，都说明制冷系统工作不正常。2、冰箱冷冻室结冰，说明温控器温差过大，停机时间过长等因素造成的，直冷式双门冰箱的冷藏室蒸发器总是结满霜而无结霜、化霜交替变化，说明温控器发生故障。3、检查制冷系统中管路的各个焊接处及蒸发器表面，看是否有渗漏的痕迹，凡渗漏处都会有油渍。4、查看压缩机回气管是否结霜，如结霜，则说明制冷剂冲入量过多，对于间冷式冰箱，如压缩机回气管结霜，还应考虑是否由于风扇不转而引起。遇到这种情况，可以打开箱门，按下门框按钮，查看风扇是否旋转。5、查看箱门是否有缝隙。如果箱门有缝隙，则冰箱保温性能差，导致压缩机开机时间长，停机时间短，而且冰箱结霜多。听1、接通冰箱电源，如果听到启动器“叭嗒”一声，压缩机在0.2秒至0.5秒内启动，随后压缩机发出轻微而且有节奏的运转声，说明压缩机启动正常。如压缩机发出沉闷的“嗡嗡”声，而后连续听到“叭嗒”的启动器触点断开、吸合的声音，有时还带有压缩机的振动声，最后可以听到热保护器“叭”的一声响，随后切断压缩机电源。此故障可以考虑以下原因：a、电源电压低，压缩机卡缸、抱缸轴。b、电动机扫堂。c、电动机绕组短路。d、电动机启动绕组开路。e、气路系统管路堵塞。f、启动继电器故障等。使用排除法，确定故障原因。2、压缩机运转时，机壳内有明显的喷气声，说明压缩机排气缓冲管断裂漏气。若压缩机机壳有破裂声，说明压缩机高、低压阀片破裂、漏气。压缩机刚停机时，听到机壳内有明显的跑气声音，说明压缩机阀板的高低压纸垫被击穿、排气减震管泄漏、阀片磨损或阀片、阀口处积碳。压缩机运转时，如果机壳发出“当当”的撞击声，说明压缩机内支撑弹簧断裂或疲劳变形。3、高压液态制冷剂通过毛细管进入蒸发器，迅速蒸发沸腾，同时发出“嘶嘶”的气流声音，并时常伴流水的声音，属于正常现象。如果听到蒸发器内有“叽叽”声，或者有断断续续的憋气声，故障通常为脏堵、油堵或者冰堵。周期性较长的断续喷气声一般为冰堵。若蒸发器内只有气流声，而且不结霜，说明系统内制冷剂基本漏完。4、冰箱有时发出断断续续的噪音，往往是由于冰箱支脚落地不稳，制冷系统管路相互碰撞以及压缩机与箱体底座螺丝松动等原因引起共振造成的。摸冰箱正常运行时，制冷系统各个部分的温度通过触摸，可以对制冷系统状况有个大致的判断。(制冷系统各个部分的温度还受环境温度的影响，环境温度升高时，冷凝器、过滤器、回气管和压缩机的温度明显升高，反之，上述部分的温度明显降低。)1、压缩机运转时，触摸冷凝器上部，应很热(大于55℃)。如不热，可能是制冷系统漏气、堵塞或压缩机没有排气压力等故障。2、正常时，触摸干燥过滤器应有热的感觉(约55℃)。如制冷系统过脏，会造成干燥过滤器温度升高，对于刚刚维修过的冰箱，如果干燥过滤器温度过高，一般为毛细管阻流偏大，制冷剂充入量过大。3、压缩机正常工作时，触摸压缩机回气管，应没有热感(接近于环境温度)。如果温度高，说明系统少制冷剂，管路微堵或系统中混入空气。如果感觉到冷或者有露水甚至结霜时，说明制冷剂充入量过多。4、压缩机机壳的温度一般在70℃以下。即使在夏季，冰箱首次开机时，压缩机经过连续长时间的工作，机壳温度也不超过85℃。5、如果蒸发器上结的霜用手一摸就脱落(称为虚霜)，并且压缩机回气管结满霜，说明充入的制冷剂过多或新换的毛细管过粗、过短。6、用手触摸蒸发器表面，如果发现蒸发器结不满霜，说明系统制冷剂不足或毛细管半堵塞。测试通过测量冰箱的温度、压力、开机与停机比、运转电流以及压缩机的绝缘电阻和直流电阻等，对冰箱进行检查。1、测温度用电机温度计测量电冰箱的温度。电冰箱的温度按国家标准吸气温度为三十二摄氏度，蒸发温度为负二十三摄氏度一下，排气温度为五十五摄氏度左右，过冷温度为三十二摄氏度左右。1、冰箱靠近墙面放置会导致冰箱发烫，也不能在冰箱的周围覆盖东西，这样都会阻碍冰箱散热，使温度上升，应该保持冰箱有足够的空间散热。2、在使用冰箱的时候不要打开频繁，频繁的打开冰箱会让里的温度升高，加大冰箱的工作量，冰箱长期处于运转状态就会使温度更高的。这时要减少开冰箱的次数。3、停用之后特别是在夏季温度很高的时候，冰箱要达到设定的制冷温度会需要很长时间，长时间的运转就会使冰箱的温度升高，冰箱一旦使用最好不要停用了。2、测压力冰箱的正常压力值在0.03~0.08mpa。a、吸气压力过高，通常由：制冷剂充入过多、新换毛细管过短、压缩机性能*的原因引起。b、出现吸气压力为负压时，通常由：制冷剂不足、系统内有堵塞现象、新换毛细管太细、太长。2、测量冰箱的开机与停机之比冰箱的开机与停机之比与它的制冷系统、保温性能、温控器性能、调节位置、环境温度、电路系统、冰箱内食品的多少以及开门次数等有着直接的关系。3、测量工作电流1、如果工作电流大于额定电流，说明制冷剂充入量过多，制冷系统微堵、压缩机局部短路。2、如果工作电流小于额定电流，说明制冷系统有泄漏或系统完全堵塞。3、测量绝缘电阻和直流电阻：(对于匝间短路不严重或匝间绝缘不良的电机绕组，用电阻测量方法很难分辨电机故障，因此只能采用测量工作电流的方法来判断)。缺少制冷剂，或蒸发器内有沉积的冷冻机油，导致压缩机效率降低。冰箱故障分类电冰箱的故障可分为电气系统故障和制冷系统故障两大类。电气系统故障分析电气系统主要包括温控部分和压缩机电动机控制部分。由此而引起的故障现象是电冰箱接通电源后压缩机不起动和接通电源后压缩机运转不停。1、首先用万用表欧姆挡测量冰箱电源插头的阻值。压缩机的三个接线端子以及与起动器之间的接线情况如图所示：C——公共端、M——运行端、S——起动端。各绕组间直流电阻值如下：运行绕组C、M两端约10.5Ω；起动绕组C、S两端约22Ω；而运行和起动绕组阻值的和即S、M端的阻值约为32.5Ω。正常时电路所有的开关触点都接通，对于重锤起动器式的冰箱，因重锤式起动器触点未通电而未接通，回路阻值为压缩机运行绕组的阻值，一般为10—20Ω左右，对于PTC起动冰箱，回路的直流电阻为起动器20Ω阻值与起动绕组串联后再与运行绕组并联，所以其电阻略小于压缩机运行绕组的阻值。通过测得的阻值来判断电路的工作状态，阻值偏大时，要检查温度控制器、过载保护器、压缩机电动机以及线路和触点接触情况，阻值偏小时一般是短路，主要检查压缩机电动机及其线路。　　2、要进一步判断还要对冰箱通电检查。通电前先检查温控器开关是否正常。如温度控制器装在电冰箱的冷藏室内，当放置的环境温度低于设计温度时不会起动运转，故有的冰箱设计了冬季补偿开关，补偿开关打开后则温度控制器感温管附近的加热器开始加热，强制升温使压缩机运转，目的是牺牲冷藏室的正常温度而保证冷冻室的温度。如果温控器内的开关都正常，而通电后压缩机不起动，可用一根导线短接重锤式起动器的两个静触点，注意导线短接时间不要太长，以不超过2s为宜，时间长将会使起动绕组烧坏。如果短接后冰箱能起动，说明起动器有故障，重锤式起动器长期起动易使触点烧坏，测量时拆下起动器，用万用表欧姆RX1挡，将两表笔插入接线柱插孔内。起动器正着放时相当于正常运转状态，即未接通，万用表测量阻值为无穷大；将起动器倒过来时相当于起动状态，万用表指示为0Ω，则说明起动器是好的。如果用导线短接后仍不能起动，就需要检查保护器。可用短接法检查保护器，将保护器的两个接线铜片短接起来，如果冰箱能够起动运转，说明保护器有故障，可能是电热丝烧断或碟形双金属片受阻不能下翻，如果冰箱仍不能起动，则是压缩机或起动器有问题。检查时，把起动器和保护器拆下，露出电动机的三根接线柱。测每两个接线柱之间的电阻值，如正常，说明电动机绕组没有故障。如不正常，不要急于拆开压缩机，可以采用直接接通电源的方法进行检查。具体办法是：用带有电源插头的两根电源线接在M、C接线柱上，也就是运行绕组上，再用螺钉旋具作为导线同时碰触M和S端，然后把插头插入电源插座，如果电动机和压缩机没有故障，就会起动。起动2s左右，就要把螺钉旋具移开，电动机进入正常运转。如果检查压缩机能起动运转，说明电动机没有故障，故障发生在电动机外部，可能是外引线折断或接线柱接触不良，也可能是环境温度过低等。否则为压缩机故障。制冷系统故障分析电冰箱不制冷电冰箱运转不停，但是不制冷，冷凝器不热，蒸发器不凉。这种故障一般出现在制冷系统。可能原因是制冷剂泄漏，或者冰堵、脏堵，或是压缩机有故障。由于制冷系统是封闭的，所以可通过观察管路表面有无油污、用手触摸各部分的温度、耳听运行声音来检查。1、检查管路表面是否有油污仔细检查冷凝器、过滤器、毛细管、蒸发器；吸气管、压缩机外壳及管路结合处。如果发现有油污，说明制冷剂泄漏。这时可切开压缩机的工艺管。如果有少量的制冷剂喷出，就进一步证明是制冷剂泄漏。如果没有油污，则需要进一步检查压缩机的温度。2、检查压缩机的温度用手摸压缩机，如果压缩机的温度不太高，和运转时差不多，说明管路畅通，没有堵塞现象，而可能是高压缓冲管破裂、活塞穿孔、排气阀同吸气阀短路等。这时可切开高压排气管，排出制冷剂。3、检查压缩机开机时的情况切断电冰箱的电源，打开箱门；使制冷系统各个部件恢复到室温。然后接通电源，电冰箱启动运转。如果开始时蒸发器结霜较好，冷凝器发热，低压吸气管发凉；由冰箱上部能听到气流声和水流声，但过一会儿，蒸发器结霜融化，只在毛细管同蒸发器结合部位结有少量霜；冷凝器不热，低压吸气管不凉，用耳朵贴近电冰箱上部听不到声音，说明出现了冰堵。这时如果用热毛巾敷在毛细管同蒸发器的结合处，又能重新制冷，则进一步证实是冰堵。如果开机的时候不见蒸发器结霜，冷凝器不热，低压气管不凉，用耳朵贴近电冰箱上部听不到声音，则可以初步认为发生了脏堵。这时，可以切断高压排气管，排出制冷剂，用手指按住排气管，启动压缩机，如果手指感到有较大的压力，说明管路发生脏堵。电冰箱制冷效果差电冰箱运转不停，但箱内温度达不到要求，制冷效果差。这可能是由于使用不当或箱门关闭不严造成的。也可能是制冷系统故障引起的。一般应先检查使用情况和箱门情况，再检查制冷系统。1、检查使用情况首先要了解环境温度。如果高于43℃，制冷效果差一些是正常的。如果环境温度不高，要打开箱门检查。如果箱内食品太多，特别是放入了温度高的食品，食品释放出大量的热量；或者打开箱门次数太多，外界热空气不断进人箱内，或者未及时化霜等，所有这些都会使电冰箱长时间运转不停，制冷效果差。2、检查箱门电冰箱箱门关闭不严，热空气会从缝隙处不断进入箱内。这可能是磁性门封条失去磁性、老化变形，或是箱门翘曲造成的。3、检查制冷系统如果使用情况正常，箱门又能关闭严密，那么制冷效果差的故障就出在制冷系统。由于制冷系统仍能工作，因此，可能是制冷剂部分泄漏、部分冰堵或部分脏堵，也可能是压缩机内部故障。检查的顺序是首先观察管路表面有无油污。如果有油污，说明制冷剂部分泄漏，这时可以切开工艺管，灌入适量的氟里昂制冷剂，再次启动运转。如果运转正常，证明是制冷剂部分泄漏。如果管路表面没有油污，可检查开机时的情况。如果开机时制冷正常，蒸发器结霜良好，在电冰箱上部能听到气流声和水流声，但过了一会儿制冷效果变差，只能听到微弱的气流声和流水声，说明是部分冰堵。如果开机时制冷效果就差，用耳朵贴近冰箱上部只能听到微弱的气流声和水流声，这可能是脏堵或压缩机内部故障，需要进一步检查。这时，可切开工艺管，灌入适量的氟里昂制冷剂，并接入气压表，启动压缩机。如果气压表所示气压下降到正常值（0.06～0.08MPa）以下，说明压缩机内部没有故障，只是管路有部分脏堵。如果气压下降到正常值以上，说明压缩机性能下降，严重时需要拆开压缩机详细检查和修理。如果制冷系统混入空气，或者制冷剂充加过多或不足，都可能影响制冷效果。制冷系统中充加过多的制冷剂，会使过多的制冷剂在蒸发器内不能很好蒸发，液体制冷剂返回压缩机中，这样压缩机的吸气量减少，制冷系统低压端压力升高，又影响蒸发器内制冷剂的蒸发量；造成制冷能力下降。同时，过多的制冷剂会占去冷凝器的一部分容积，减少散热面积，使冷凝器的冷却效率降低，吸气压力和蒸发温度也相应提高，吸气管出现结霜现象。遇到这种情况，必须及时将多余的制冷剂排出制冷系统，否则不但不能提高降温效果，反而使压缩机有液击冲缸的危险。制冷系统充加的制冷剂过少时，会使蒸发器的蒸发表面积得不到充分利用，制冷量降低，蒸发器表面部分结霜，吸气管温度偏高。遇到这种情况，可以补充适量的制冷剂。常见故障及检修通电后电机不起动且无嗡嗡声1、故障原因：保险熔断
