The most common problem with air heaters is the heating tube inside. Because the air electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature. It is heated by heating tubes, so here are a few problems that will occur:
1. In the case of poor quality of the heating tube, the heating tube will break;
2. If the insulation resistance is not handled well, it will leak electricity;
3. The power is not right.
