What to do if the humidifier fan is broken.car aroma humidifiers

　　1、 In case of startup tripping

　　If the power is turned on and the fuse is burned or tripped, it is certain that the 4007300V filter electrolysis and power supply tube (4N60) are faulty. Usually, two of the 4007 are faulty, and the other two are not, so they should be replaced completely.

　　2、 When the fan is turned on

　　The fan is running normally at 38V, but there is no fog. Open the atomizing fin to fix the heat sink, and check if the wiring is loose and if there is water ingress. The atomizer can only be replaced and cannot be detected for quality.

　　3、 When the fan does not turn on

　　The power on does not burn the fuse, but the fan does not rotate and there is no 38V. Check whether the C-pole of 4N60 is 300V, whether the Ube is around 0.5V, whether the switch transformer is disconnected, and whether the optocoupler is damaged.
