Hi, I own a split a/c 12000 btu, the problem is that the last two days it kicks down the fuse. this happens when the compressor tries to start. the a/c was working fine for the past three years. do you thing that there is a problem with the compressor itself? or there is something else that has to do with the electrics?

I think the problem would be the compressor. unplug the unit and if you know how to test the resistance of the terminals, then do a ground check on the compressor. if it is grounded, then it is broke. if not grounded, then observe it as it runs if it would start, if it can not start then you still have to check the starting components such as the capacitor and the wirings associated with it.

tnx for using Fixya
