Seek the circuit diagram of Lianchuang Hongyun fan. It is mainly found that there is a small ceramic capacitor inside the motor of this fan (no

From the photo, this widget is not a ceramic capacitor, but a common temperature fuse in the motor winding of an electric fan. If the winding temperature rises abnormally due to motor failure, the temperature fuse will automatically blow, thus disconnecting the power supply of the motor and protecting the winding from being burned by high temperature. After the temperature fuse is blown, it can be replaced according to the parameters, and then check whether the winding or other components are short-circuited.
