acc线在钥匙孔acc后面，acc电源线可以理解为车钥匙打到acc位置后就有电的线。acc的英文全称是“adaptivecruisecontrol”，中文意思是“自适应巡航控制”。

acc线：

1、acc电源指钥匙打到acc挡的电源，也就是发动机起动过程中要断开的电源，这部分电器件一般所带的负载较大，且在汽车起动时不必工作，一般有点烟器电源、空调电源、收放机电源、刮水器电源等；

2、acc电源是由车钥匙控制的，把钥匙放在acc位置，可给车上的附件提供电源，但车辆不能启动；

3、ACC是AdaptiveCruiseControl的英文简写，中文意思是自适应巡航控制电源，一般应用于汽车由车钥匙控制，为汽车音响等部分器件供电。

原因是：1、误按ESP的关闭按键。2、传感器接线头松脱或发生故障。3、线路短路或保险丝熔断。4、软件问题导致信号传输不良。5、ABS泵体故障。系统存在故障有这两种可能性：1、若行驶中只有ABS警报灯亮：表示ABS系统中存在故障，但轿车仍可靠常规制动系统制动，应尽快请专业人员检修。

2、若行驶中ABS警报灯和制动系统警报灯同时点亮：则表明ABS和制动系统均存在故障，制动特性将发生变异。如果是后者，则必须立即停止行驶，检查制动液液位，若液位位于“min”标记，则切不可继续行驶，须请专业人员检修。若液位正常，则表明ABS系统可能出现故障，即ABS系统调节功能失效，就只有普通刹车系统起作用，容易在刹车时导致后轮较快抱死，导致侧滑。此时应该谨慎驾驶，尽快进行维修。

自从液晶电视上市以来，逐渐受到了人们的喜爱，很多人家里都安装了液晶电视。和普遍的电视机相比，液晶电视比较省电、较为环保。但是对于电器来说，使用久了，出现故障也在所难免，那么该如何维修呢？

基础知识

组成结构

液晶电视机的组成原理，大体有4个主要功能模块电源板，电视主板，逻辑板，背光模块，以及屏线，遥控器，按键输入和喇叭输出。

电源板

顾名思义，电源板负责整台电视的供电。功能好比人的心脏，给人全身输送能量。如果电源板坏了，就像人的心脏停止跳动，电视机自然就不能工作了。

很多黑屏，背光不亮，指示灯不亮，遥控按键不起作用等现象都是因为电源板故障引起。

电视主板

电视主板是整个电视机控制的核心，也可以说是电视的大脑。

如果电视主板出现问题，可能导致指示灯不亮、或者指示灯颜色异常、遥控按键无响应、黑屏、花屏等现象。

逻辑板

逻辑板也称TCON板，是信号中转站。负责将主板的LVDS信号转换成屏能处理的TCON信号。

如果TCON坏了，可能导致画面黑屏，花屏，条纹干扰，屏闪，屏保等异常现象。

背光模块

背光模块的功能是给电视机显示提供背光光源。

如果电视背光不亮，很有可能是背光模块出现了问题。

LVDS信号线

屏线，又称差分信号线。如果接口松动，接触不良，很容易导致黑屏，雪花点干扰，花屏等异常现象。

注意：4K电视，因为数据量大，LVDS信号线已无法满足传输要求，一般都采用V-BY-ONE的信号线传输。

遥控接收头

遥控接收头，也称IR，负责接收遥控器的红外控制信号。如果按遥控器没有反应，可能是遥控接收头出现问题。

按键板

如果遥控器可以正常操作，但按键板不起作用，估计是按键板或者相关电路坏了。

三合一板卡

将背光模块，电源板和电视主板集合到一块板卡上，俗称三合一板卡。将背光模块，电源板和电视主板集合到一块板卡上，俗称三合一板卡。

随着产品的标准和规范化，电视模块将越来越简化。目前市面上的电视，里面的模块基本都简化成两片电路了，一块三合一主板加一片逻辑板。

工作原理

如上图，红色的箭头是供电电路，蓝色的箭头是信号电路。

电源板负责将220V交流电压转换成各个模块工作所需的直流电压；

电视主板负责处理按键信号，响应遥控器信号；

控制电源板开关，直接或间接控制背光模块；

接收各类视频信号，图像转化成LVDS信号输送给逻辑板；

声音信号输出到喇叭；

逻辑板主要功能是将电视主板输出的LVDS信号转换成液晶屏能处理的TCON信号；

背光模块负责给背光灯条供电。

维修常用工具

螺丝刀

螺丝刀是工具，分手动或电动，用于旋拧（安装）和旋松（除去）螺钉。

镊子钳

夹持导线、元件及集成电路引脚等。

万用表

，万用表又称为复用表、多用表、三用表、繁用表等，是电力电子等部门不可缺少的测量仪表，一般以测量电压、电流和电阻为主要目的。

示波器

示波器是一种用途十分广泛的电子测量仪器。它能把肉眼看不见的电信号变换成看得见的图像，便于人们研究各种电现象的变化过程。

温度可调热风枪

热风枪主要是利用发热电阻丝的枪芯吹出的热风来对元件进行焊接与摘取元件的工具。

电烙铁

电烙铁是电子制作和电器维修的必备工具，主要用途是焊接元件及导线。

锡丝

锡丝的特质是具有一定的长度与直径的锡合金丝，在电子原器件的焊接中可与电烙铁或激光配合使用。

维修技巧

基本维修的方法

直观法

肉眼观察烧黑的地方，看有无连接线松动及元器件击穿的情况。

触摸法

用手触摸关键部件，观察供电部分发热情况(数字板)，特别是对老化几小时后出现的软故障情况比较实用。

问题法

了解故障出现的具体状态(比如雷击、打火、冒烟、积水及以及人为操作等)。

测量法

使用万用表、示波器测量(有些情况可用指针式万用表交流来代替示波器测量一些普通的信号)。

代换法

有条件的情况下，可以代换电源板，数字板，高频板，背光板，屏，LVDS数据线，软件等，这种方法维修快。

排除法

缩小检修范围，准确判断故障位置(如信号源部分、信号通道部分)。

逻辑检修法

该方法要求对所修板件的信号流程、电源逻辑关系非常熟悉，可以确定维修的顺序：是先从后级向前级检修，还是单一通道向公共通道检修等等。

满足法

先大体确定故障部位后，再检修部分电路的工作条件是否满足(特殊情况下可人为制造工作条件)。

对比法

条件允许的情况下，可以对比好的板件进行检修，也可以对比同一板件上相同的电路(对称电路)来进行检修。

先软件后硬件

软件涉及的故障范围广，但是需要检修的范围小，对于一些软故障，建议先升级软件。

初步检修流程

维修口诀

液晶维修并不难，工作原理记心间；

电压来自电源板，亮度来自背光源；

信号处理机芯板，显示分配控制板；

5V供电最勤劳，一年四季歇不了；

12V供给机芯板，中放功放向它看；

24V送到背光板，无它屏幕缺光源；

机芯板子是领导，开关信号向它要；

电源模块背光板，电平高开（机）低关；

PWM脉冲很重要，少了亮度提不高；

LVDS线要求高，变质松动有干扰；

液晶电视不普通，程序经常闹罢工；

三天两天发神经，需要复位来摆平；

液晶屏幕很脆弱，要维修时细（心）操作

平板维修费用高，学好技术很辛劳；

赚钱固然很重要，安全二字记心牢。

常见故障分析

显示器整机无电

1、电源故障

这是一个应该说是非常简单的故障，一般的液晶显示器分机内电源和机外电源两种，机外的常见一些。不论那种电源，易损的一般是一些小元件，象保险管、整流桥、300V滤波电容、电源开关管、电源管理IC、整流输出二极管、滤波电容等。这些常用的芯片在专业液晶配件店里都能买到。

2、驱动板故障

驱动板烧保险或者是稳压芯片出现故障，有部分机器是把开关电源内置，输出两组电源，其中一组是5V，供信号处理用，另外一组是12V提供高压板点背光用，如果开关电源部分电路出现了故障会有可能导致两组电源均没输出先查12V电压正常否，跟着查5V电压正常否，因为A/D驱动板的MCU芯片的工作电压是5V，所以查找开不了机的故障时，先用万用表测量5V电压，如果没有5V电压或者5V电压变得很低，那么一种可能是电源电路输入级出现了问题，也就是说12V转换到5V的电源部分出了问题，这种故障很常见检查5端稳压块(常见型号8050SD-LM2596-AIC15-01等)。

另一种可能就是5V的负载加重了，把5V电压拉得很低，换一种说法就是说，后级的信号处理电路出了问题，有部分电路损坏，引起负载加重，把5V电压拉得很低，逐一排查后级出现问题的元件，替换掉出现故障的元件后，5V能恢复正常，故障一般就此解决，也经常遇到5V电压恢复正常后还不能正常开机的，这种情况也有多种原因，一方面是MCU的程序被冲掉可能会导致不开机。还有就是MCU本身损坏，比如说MCU的I/O口损坏，使MCU扫描不了按键，遇到这种由MCU引起的故障，找硬件的问题是没有用的，就算你换了MCU也解决不了问题，因为MCU是需要编程和写码的，在没办法找到原厂的AD驱动板替换的情况下，我们只能用通用A/D驱动板代换如151D或161B等。

显示屏黑屏，无背光，电源灯绿灯常亮

斜视液晶屏有显示图像，是因为MCU问题造成没有输出开关控制电压，可以直接提取3端稳压块的。

(AIC1084)3.3V代替，修理高压板的思路(电源保险丝--开关控制管--电源管理IC--推挽发大管--电源开关管--DA转换电路(储能电感整流管)--LC升压电路(升压变压器、升压电容)--耦合电容--灯管。

屏幕亮线，亮带或者是暗线

这种问题，一般是液晶屏的故障。

亮线故障一般是连接液晶屏本体的排线出了问题或者某行和列的驱动IC损坏

暗线一般是屏的本体有漏电，或者TAB柔性板连线开路以上两种问题基本上就是给机器判了死刑了，没有维修价值的，因为一块屏的价格太高了。(广州有专门更换码片的，收费极高，返修率也高)。

花屏或者是白屏

这种问题一般是屏的驱动电压出了问题，先换驱动板和驱屏线试验，若不行检查屏背板供电电路。

维修思路：驱动板5V转3.3V的稳压块(AIC1084)是否有供电输出--屏体驱动板保险丝(F)-3.3V--DC转换电路--负压形成IC(-7V)--行列驱动IC。

AAT1101AM150XN05屏电源管理芯片，损坏后表现为白屏开机图像暗淡等。

AAT1164M170EG01新款屏通病，主要用在明基FP71G+液晶显示器上面。用一段时间会白屏、关机在开用一段时间又出现白屏。本芯片为液晶屏高压产生及管理芯片、明基液晶显示器常坏、故障为：白屏。

偏色故障

一般可以进入工厂调整模式进行调整。

维修思路：更换屏线和转接板--重写驱动程序--驱动板坏(不常见)--屏背板的控制IC坏(不常见)--拔掉屏线观察背光颜色(背光偏色为灯管老化)--换灯管。

字符虚或拖尾

维修思路：检查VGA信号线，重点看RGB三色线的地线是否连接正常--更换屏线或转接板--重写驱动程序--换驱动板--LCD屏背板信号接口 IC坏--LCD屏背板对比度电位器调整--LCD屏导光板错位--偏光片错位。

LCD屏幕内部有污点

维修思路：擦拭或更换换保护膜--拆开屏体清洗外层偏光片和有机玻璃(用棉球纯净水处理)--风筒吹干。

LCD屏漏光或光线不均

维修思路:重新安装灯管--调整导光板。

LCD屏亮点

一个或二个大的亮点，可以尝试轻轻用指尖压亮点，可消失,说明多为此像素的开关管和电极虚连小的黑点和灰点有可能是内部导光板或偏光片有灰尘造成可清洗处理。

LCD屏亮度低

检查高压板ADJ亮度调节电路--换灯管--换高压板---调整或更换导光板。

错误提示超出频率范围

检查信号线--重写MCU驱动程序--更换EPROM--重写EPROM程序--换驱动板。

通电后不按开关按键即白屏，出现背光按键后图像可正常显示

高压板接口的开关信号和ADJ信号反接造成部分属于驱动板MCU的开关信号输出不正常，可以重写MCU程序修复--换MCU。

补充一点，对于灯管老化的屏更换时要搞清灯管的尺寸，因为尽管屏幕尺寸一样，但是灯管长度与粗细略有差异，在找不到相同尺寸灯管的时候，如果能用短灯则好，如果不能使用，稍长的的灯管用手术刀小心切除屏框，并用热缩管做好绝缘。

注意事项

电视机是有电高压的一种电器，维修时有关的安全问题一定要注意。

1、打开机壳：要注意不能用蛮力打开机壳，如果太紧打不开，一定是还有螺钉或卡扣没有松开，要再仔细找找；拉开机壳时有的电视机电路板与机壳之间会有电线相连，要注意不要拉坏，比较好先折下机壳上固定的电路板；拉开机壳时要拿稳机壳，不要脱手掉下，否则容易砸到显像管管径，一旦砸断可就麻烦了。

2、要注意电视机的“热地”：有的电视机的电路板的地是“热地”，就是与市电没有隔离，如果恰巧电视机的电源插头又将未隔离的电视机的“地”端插到市电的“火”线上，那么维修时如果你不小心碰到电视机的某个接“地”的部分，就有触电的危险。一方面触电本身很危险，另一方面人在触电时身体会发生不由自主的痉挛，一旦把电视机拉到地上，就又出大麻烦了。解决这个问题比较好是用隔离变压器，如果没有，比较好在电视机通电时能调整好插头方向，使电视机的“地”接到市电的“零”线上，这样可以使电视机比较容易碰到的地方不“电”人，但是电视机里还是有与“火”线相连的强电的，仍然要小心。

3、要注意电视机内的高压：在更换行输出变压器的时候，一定要用万用表笔或其它导线将显像管高压帽下的高压泄放干净，否则在摘下高压连线时会受到高压电击，同样比较危险。

如何保养

1、保持干燥

放置的中央，环境要保持干燥并远离化学药品。假如放置环境湿度很大，电器内部就会结露，容易形成漏电、短路等。平常使用的发胶、灭蚊剂等都是高挥发性化学品，也会对液晶显现屏形成损伤。

2、亮度调低

日常使用，尽量防止长时间显现同一张画面。长时间工作容易惹起内部老化或烧坏，特别糟糕的是长时间内显现同一画面，可能会招致某些像素过热，形成内部产生坏点。而这种损坏不能修复。因而不用时应该关闭显现屏或选择屏幕保护程序，或者把显现屏亮度调低点。

3、不能频繁清洗

液晶显现屏不能频繁清洗。正确的清洁办法是拿一块沾有少许玻璃清洁剂的屏幕擦布，轻力把污迹擦去。注意不要让清洁剂流到屏幕、屏框接口中，以免出现短路。也不要用硬质毛巾擦洗，以免刮花屏幕。还要定时定量擦洗。

4、制止坏习气

更换的方法如下：

1、这个建议在闪光继电器上取电就可以了；

2、只不过要取从开关过来的，同时还需要加继电器才可以的，不然会烧保险和开关的；

3、转向灯是在车辆转向时开启以提示前后左右车辆及行人注意的重要指示灯。转向灯灯管采用氙气灯管，单片机控制电路，左右轮换频闪不间断工作。转向灯采用闪光器，实现灯光闪烁；

4、它的开启时间要掌握好，应在距转弯路口100米左右时打开，如果并线更需提前开启。开得过早会给后车“忘关转向灯”的错觉，开得过晚则造成后车或行人因反应不及而发生事故。

xrv是磨砂黑保险杠。本田xrv原装前保险杠价格是1500元左右，后原装保险杠的价格大概是1000元左右。

汽车保险杠是吸收和减缓外界冲击力、防护车身前后部的安全装置。许多年以前汽车前后保险杠是用钢板冲压成槽钢，与车架纵梁铆接或焊接在一起的，与车身有一段较大的间隙，看上去十分不美观。

随着汽车工业的发展和工程塑料在汽车工业的大量应用，汽车保险杠作为一种重要的安全装置也走向了革新的道路。今天的轿车前后保险杠除了保持原有的保护功能外，还要追求与车体造型的和谐与统一，追求本身的轻量化。

轿车的前后保险杠都是塑料制成的，人们称为塑料保险杠。 一般汽车的塑料保险杠是由外板、缓冲材料和横梁三部分组成。其中外板和缓冲材料用塑料制成，横梁用冷轧薄板冲压而成U形槽；外板和缓冲材料附着在横梁。

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、压缩机性能无法维持正常运行的原因引起。

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。

冰箱的保养

定期适当保养可以延长冰箱的使用寿命。保养冰箱前务必拔下电源插头。

1、经常清理冰箱背面或底部冷凝器和压缩机上的灰尘。可使用吸尘器或毛刷除尘。注意不要用湿布去擦冷藏器和压缩机上灰尘。

2、冰箱长期停用时，应先切断电源，取出箱内一切食品，将箱内外清理干净，敞开箱门数日，使箱内充分干燥并散掉冰箱内的异味。

3、检查排水管。如果排水管堵塞，水就会漏到冰箱内。要用铁丝捅一捅排水管，除去积在排水管上的东西。

4、不要忽略门封胶条的清洗，将漂白剂用10倍的水稀释后用牙刷蘸湿清洗，最后用水将漂白剂冲去。胶条脏污易老化，会影响冰箱的密封性，增加耗电量。

5、检查振动、噪音以及压缩机的温度。运行中摸压缩机外壳，不应有明显的振动感，白天不应听到压缩机明显启动的声音。

6、注意检查电源线上是否有裂缝，防止漏电。

7、用温水或中性洗涤剂将冰箱内外清洗并擦干，敞开冰箱门通风干燥一天。

清洁冰箱外壳最好每天进行，用微湿柔软的布每天擦拭冰箱的外壳和拉手。清理内胆前先切断电源，把冰箱冷藏室内的食物拿出来。软布蘸上清水或食具洗洁精，轻轻擦洗，然后蘸清水将洗洁精拭去。拆下箱内附件，用清水或洗洁精清洗。清洁冰箱的“开关”、“照明灯”和“温控器”等设施时，请把抹布或海绵拧得干一些。内壁做完清洁后，可用软布蘸取甘油(医用开塞露)擦一遍冰箱内壁，下次擦的时候会更容易。用酒精浸过的布清洁擦拭密封条。如果手边没有酒精，用1：1醋水擦拭密封条，消毒效果很好。用吸尘器或软毛刷清理冰箱背面的通风栅，不要用湿布，以免生锈。清洁完毕，插上电源，检查温度控制器是否设定在正确位置。
