The Law of Engineers: The appliance is broken, and the capacitor is always wrong.

As early as 2006, my friend Alan Martin who worked at Texas Instruments had a maxim: “Always a capacitor goes wrong!”. He found that many test equipment failures were caused by dry electrolytic capacitors or failure of tantalum capacitors.

Although Alan is referring to electronic products, the central air-conditioner that was recently broken down in my house once again confirms his phrase “always capacitor goes wrong!”. I went to the compressor on the side of the house and found that the fan on the top of the compressor did not turn. I use a bread knife to turn the fan. It has no restrictions. I found on YouTube that "AC fan does not work", a video says to start/run capacitors. There are several other videos about broken start/run capacitors. I opened the machine, and sure enough, the capacitor swelled. This look is a troublesome thing.

The compressor made a terrible noise, as seen in a video, and I suspect there was a lack of cooling. I do not like the small chip in the black capacitor flange. It is very old and has been used for 16 years. Now that a capacitor has been broken, the next one is definitely it.
