air conditioner failure的意思|示意

If above fault has been ruled out, air conditioner still cooling, heating effect is poor, then can judge compressor failure or low efficiency.

若以上故障已排除，空调器仍然制冷、制热效果差，则可判断压缩机失效或效率降低。

I didn't understand why at first, but soon I learned that there is a great shortage of electricity supply in our city-my air-conditioner turned off because of a power failure midnight.

我起初不明白为何，但很快我得知电力供应短缺，便关掉空调午夜时停止使用。
