3.5 microfarad capacitor! Suddenly the fan in my room went off. At first I thought the power was off, but I realized there was a problem with the fan as my WiFi was not turned off. Although I'm not a student of physics, I realized that the fan capacitor was damaged. Although I have never had the experience of installing a capacitor before. But this time I thought let's fix the fan myself. I bought a 3.5 micro farad capacitor from the market which cost $0.99 I took a good look at the connections of the previous damaged capacitors. Make sure there is no mistake in connecting the next capacitor. With the help of some tools I was able to easily connect the fan to the capacitor. The fan will start running again to switch on the fan. For a while I felt like an engineer. I did it :)
