【参赛】格力变频空调显E6
/pstatus" 本帖最后由 杨冬林 于 2016-6-18 12:36 编辑 /ibr /br /型号:格力KFR-26GW/K(26556)FdD3Abr /故障:不制冷 空调几分钟后出现代码E6 br /检查:内机运转正常,遥控器应用正常。外机无法运转,三灯熄灭:交流电压223V正常,信号2.7~12.8V正常,直流+- 310V正常,低压15V/12V/5V不达标。br /处理:摘板 维修br /此机已经6年多,已出保,换板或维修该板?客户选择维修该板。br /主板插电检查:(目标电源电压部分先弄好它)br /交流电压:~226V (正常)br /桥堆P1~G1=312V (正常) br /桥堆 P2~G2=195V (正常)br /场管D/ S GT30J122 (已开路)br /TOP243YN电压 (不正常)D/S端已接近开路状态br /TOP243YN出现问题时:(具体正常参数在下图有标)br /三个大电容自身已冲电量是无法自己释放电。务必给予放电(用220V灯泡60W~100W) 否则会被电危险(我拆外机主板时被电过,滋味你懂)。更换TOP243YN之后就不会(约有3分钟左右的放电时间)被电的问题。各稳压管电源电压 输入与输出 电压很低,在断开稳压直流电压之后的负载与保护电路,才能确认TOP243YN 的 震荡分配集成电路电压的基本 通断情况,维修经验给予判断TOP243YN是否正常是关键。br /更换配件:绝缘型场管GT30J122 、 开关电源分配集成TOP243YN br /特别提示个:在测量U406稳压集成7815输出时,切记 表笔负极务必的搭在桥堆G2位置(与搭在另一组15V/12V/5V不同的负极U404散热片上),否则,测量出来的数值只有2.3左右V。br /在此平台希望与大家继续交流br / br /ignore_js_opguestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="492370" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/49/23/70_100_100.jpg" makefile="forum.php?mod=image&aid=492370&size=100x100&key=906a667f192ffe7f&type=1" inpost="1" alt="2.jpg" title="2.jpg"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong2.jpg/strong em class="xg1"(95.26 KB, 下载次数: 97)/em/ppa href="page-492370.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_492370" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=492370&handlekey=savephoto_492370"保存到相册/a/pp class="xg1 y"2016-6-18 10:17 上传/p/guestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="492371" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/49/23/71_100_100.jpg" makefile="forum.php?mod=image&aid=492371&size=100x100&key=cbc1286734671c3e&type=1" inpost="1" alt="3.jpg" title="3.jpg"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong3.jpg/strong em class="xg1"(130.2 KB, 下载次数: 102)/em/ppa href="page-492371.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_492371" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=492371&handlekey=savephoto_492371"保存到相册/a/pp class="xg1 y"2016-6-18 10:18 上传/p/guestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="492372" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/49/23/72_100_100.jpg" makefile="forum.php?mod=image&aid=492372&size=100x100&key=049d248c91e20bfc&type=1" inpost="1" alt="4.jpg" title="4.jpg"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong4.jpg/strong em class="xg1"(131.36 KB, 下载次数: 95)/em/ppa href="page-492372.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_492372" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=492372&handlekey=savephoto_492372"保存到相册/a/pp class="xg1 y"2016-6-18 10:18 上传/p/guestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="492373" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/49/23/73_100_100.jpg" makefile="forum.php?mod=image&aid=492373&size=100x100&key=087bad3f38f4c5b7&type=1" inpost="1" alt="5.jpg" title="5.jpg"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong5.jpg/strong em class="xg1"(112.23 KB, 下载次数: 184)/em/ppa href="page-492373.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_492373" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=492373&handlekey=savephoto_492373"保存到相册/a/pp class="xg1 y"2016-6-18 10:18 上传/p/guestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="492374" src="https://www.jdw
