I was sitting in my room when I noticed that the ceiling fan was sparking and causing fumes. I tried turning it off but neither it stopped spining nor sparking. I'm really worried about whether it will cause a fire or something. It stopped only upon switching off the main supply. Pls help me asap.
With a lot of new ceiling fans, the "switch" in the box in the wall is nothing more than a wireless transmitter and the fan is permanently wired at the ceiling through the wireless receiver. So if that receiver unit fails shorted, the fan cannot be turned off. If you are not comfortable with electrical work, this is something that will require the services of a qualified electrician.
