1. The heating plate is damaged. Generally, the kettle is changed directly.
2. The thermostat or temperature fuse is damaged, so that the heating plate cannot be electrified. Just replace the thermostat or fuse directly.
3. The internal circuit is damaged, so that the heating plate is not electrified, and the circuit is directly replaced.
4. The reason of scale. When the electric kettle is used for a long time, a thick layer of white mineral deposits, that is, scale, will stick on the surface of the electric heating pipe. Scale is not easy to conduct heat, which not only increases power consumption, but also affects the service life of electric kettle.
