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

3. The wiring of the overtemperature sensor is incorrect: when multiple electric heaters are used on the same skid, the wires may be connected and plugged by mistake. For example, there are three electric heaters in parallel to heat the natural gas, 1 # and 2 # heaters are running, and 3 # heater is unnecessary. If the overtemperature sensor of 2 # heater is connected with 3 # heater by mistake, and the flow stops suddenly, 3 # sensor can not turn off 2 # heater all the time, and the heater is burnt out after all.
