1. Heating and deformation of the warm source line plug.Analysis and maintenance: The phenomenon of fever after using the electric heaters for a long time, and even the deformation of the table, which is mainly related to the power socket.Most of the warm power is between 1000 ~ 2000W, which is much greater than the power of ordinary home appliances such as a fan (only about 50W), so it must be used with a special power outlet with a rated current of 10A or more. If the capacity is too lowAnd passed on the power plug plastic cover to make it deform.Therefore, the use of warm -up use of a regular special socket above 10A is like using large home appliances such as air conditioners. For warm plugs with severe deformation, they must be replaced as soon as possible to prevent accidents.
2. The far -infrared heater does not work after power generation.Analysis and maintenance: First of all, check whether the power supply plug is inserted well, whether the safety switch is well exposed, whether the in -machine lead is removed welded or falling off, and whether the bust is overheated.It is not bright, and the fan motor does not work.The maintenance method of this fault is: (L) check the power plug; (2) the mobile electric heater to a relatively flat ground to prevent poor safety switches in the ground and unevenness;Or the lead falling off the failure point; (4) to check whether the fuse is melted on the road with a multimeter, otherwise the fuse will be replaced;
3. PTC warm air guidance winding leaves are invalid.Analysis and maintenance: The wind guidance leaves are invalidated. Although it does not affect the thermal air supply of the airwalk, its effective expansion of the air supply surface is limited.The main causes of faults are: (L) The leaf driving motor has been damaged; (2) the control line pulls the corresponding thyroid control damage;To repair the leaves, you need to disassemble the case.The 220V municipal power is directly connected to the electrical side of the motor to determine whether it is intact; if the motor is intact, check the silicon control and the current limit resistance.
4. Remote heater remote control.Analysis and maintenance: First check whether the remote control battery is invalid or poor in contact due to the long use time. If it is normal, the remote control is just removed to check whether the transmitted tube is dropped or welded by the welding point.Make up for welding.If the remote control is normal, it is usually a receiving head failure for the line.Disassemble the receiving head and check whether the two pins of the receiving head are removed from welding due to vibration. If the pin does not have the welding, the failure can be eliminated after welding.
5. After using the PTC heater for a period of time, the heat air volume is significantly smaller, and occasionally hear the sound of "click".Analysis and maintenance: The heating principle of this type of heater is: the use of axis flow wheels to force indoor air to circulate through the PTC heater to increase room temperature.The PTC material has a constant temperature specialty, and the stronger the airflow passes, the more ideal the thermal exchange effect. However, after a period of use, the air inlet filter is full of dust, resulting in a decrease in air volume, resulting in a significant difference in temperature increase.Some models will also weaken the airflow, so that the temperature of the PTC heating component is too high, which will cause the temperature controller to protect. After the power is disconnected, the PTC temperature gradually decreases, and the resistance value is reduced.The disconnection affects the heating effect.During the maintenance, after the filter is removed and cleaned, the heater can be restored to normal work. Therefore, the filter should be cleaned frequently with PTC heater.
