下午听到声音不太对，到外面一看空调机有声音但是风扇不转，家里的出风口有风可是
不凉。 我把thermostat的温度调高了一下这样空调就停了，过了10分钟再把温度调低
，这次外面的空调机连声音也没有了 ，当然风扇也不转。 地下室的furnace那里的风
扇还是转，出风口也有风。
请教一下可能是什么问题，如何诊断？ 谢谢！ |

1) condenser fan motor start capacitor
2) condenser fan motor
If the condenser fan doesn't spin, it's better to shutdown the AC. The
compressor might overheat.
It costed me $300 to have condenser fan motor replaced. BTW, my unit doesn't
have condenser fan motor start capacitor, which is not typical. |

发帖数: 135 | 5 fan motor问题不会和 compressor联系上，因为是并联在contactor。按照2楼说的，再
加上4楼的contactor check就好了。 |

发帖数: 57 | 6 多谢大家，看到capacitor鼓了，amazon买了一个10块钱的换上就好了，幸好这几天不
热，不需要空调。
这个capacitor坏这么常见，是不是可以买一个在家里备着？ 我看我从amazon买的
review也不怎么样，大家有推荐哪里买capacitor吗？ |
