What are the four kinds of faults that are easy to occur in electric vehicle heaters?

1. Current cutoff: In the current cutoff condition, if the temperature control of the electric vehicle heater is controlled by the outlet temperature, the sensor signal cannot supply the correct signal, which always requires heating, and the electric heater is getting hotter and hotter. If the over temperature sensor operates, the power supply can be blocked. If the over temperature sensor does not operate, either the electric heating element will burn out, or the container will crack or melt, regardless of which situation occurs, Unexpected results may occur in explosion-proof occasions.
