Goodman system install in 2008. The A/C is not cooling
at all. I checked the capacitor, it still looks new,
and I can't find any visible sign of problem from its look.
When I turned on the A/C, I could hear it 'click'. And
I can hear the small converter humming. However, I didn't
hear the compressor's loud humming noise. The fan is
turning. I tested the temperature of the two wires/tubes,
not warm, not cold. So it looks to me the compressor
does not work, although of course I don't really know. | j*****I

发帖数: 535 | 3 我去年碰到过类似问题 症状一模一样 也是goodman system
不过很老 installed 1980s
换了capacitor就好了
新系统 应该问一下installer 想钻研可以先查一下unit manual吧

很多年以前我换过一个电容，但是那个看起来就坏了。
这次这个电容还是闪闪发亮，外观上看不出一点问题。
不知道这种情况下，是电容坏的概率大还是压缩机坏的概率大。
另外有人提到如果冷冻液漏了，也会触发压缩机保护，
不知道怎么查。

发帖数: 2895 | 5 你这个感觉压缩机还在工作吧，只是风扇没转造成不能制冷，我去年也是这样的毛病，
自己换了风扇的motor（连带也换了capacitor）就好了

发帖数: 1649 | 6 楼主这个风扇/电容都可以，电路也工作。那个click是冷冻液回路的电磁阀在工作。压
缩机肯定没工作，所以没有温差。如果是空置很久的房子，多半是冷冻液漏光了，让人
来加液查漏，不行再查压缩机电路。 | d**e
