空调室内机与外机都不运转。电磁开关及变压器的更换 Outside condenser unit does not run What's wrong?

空调的室内机及室外机都不运转？检查发现温控器上没有信号电，因为室内机的变压器烧掉了。变压器烧掉的原因是室外机的电磁开关坏了，电阻太低，导致电流过大，而室内机电路被别的维修人员更改，更改后，在24伏低压边，没有放保险丝。以前的维修人员而且没有把盖子封好，导致空调漏气。AC outside condenser unit and indoor air handler unit did not run due to transformer was burned out. The contactor of the condenser unit had a very low om resistance which led to high current, and burned the transformer since there is no fuse on the low voltage side. The wiring of the indoor air hander was modified by other technician who bypassed the fuse on the control board, but didn't put a fuse on the secondary side of the transformer. Also, the cover of the air handler was not sealed by another technician.
