Reasons about air purifier not workingIf the air purifier is not working, it may be that the motor is broken, the control panel is broken, the power supply has a problem, or the exhaust net in the air purifier cannot reach the humidity index of the filter screen, resulting in the accumulation of water in the internal pipes, which makes the exhaust net The exhaust is not smooth, which will also cause the air purifier not working.
Maintenance method of air purifier not working
If the air purifiers doesn't work, cannot be turned on, and is accompanied by a prompt sound, you can first check whether the top air outlet grille and the filter compartment door are installed in place. In order to ensure the safety of users, the air purifier adopts a double Safety protection mechanism, one is designed on the air outlet grille at the top of the fuselage, and the other is in the filter compartment door. During the operation of the air purifier, if the air outlet grille or the filter element compartment door is accidentally opened, the safety mechanism will be triggered to stop the air purifier from working quickly to ensure the safety of the user. If you need to turn it on again, you need to reset the top air outlet grille and the filter compartment door, and then press the power button.
1. The power indicator light is off, and the air purifier fan not working
If the indicator light is not on, it is usually because the power fuse is blown or the high-voltage generating circuit is faulty. Check whether the fuse is blown. If it is broken, you should find out the cause and replace it. Check if the booster transformer is burned out. Use a multimeter to measure the resistance. value, if the coil is short-circuited, the transformer of the same type should be replaced.in addition,you need to Check whether the rectifier tube and capacitor of the voltage doubler rectifier circuit are damaged, and whether the oscillator stops vibrating.
2. The power indicator is on, but the air purifier fan not working
The power indicator light is on, indicating that the high-voltage circuit is energized normally, and the air purifier fan may be faulty. Check whether the fan blades are stuck by other objects and whether the bearings are seriously worn. If there is nothing wrong, then check whether the motor leads are broken and whether the windings are damaged. It can be measured with a multimeter. If the winding is open or disconnected, the fan motor of the same specification should be replaced.
In addition, if the air purifier does not work because of a power failure, the working power of the air purifier is from the ordinary 220v AC voltage, and the output voltage is positive and negative. After the air purifier is plugged into the power supply but cannot start to work. It is necessary to reset the power supply to make the plug board return to normal. Then turn on the power to restore the settings and let the air purifier work normally.
Anyway,when the air purifier is not working,the user can first operate according to the corresponding prompts, check the reasons one by one, and then repair it according to its method.
In the process of daily use, to avoid the air purifier not working the filter element should be replaced regularly, the dust in the chassis should be cleaned regularly, and the air purifier should not be placed against the wall or furniture as much as possible.
