Reasons of Abnormal Startup of Humidifier in Winter

　　When the temperature becomes low in winter, some electrical problems may occur, such as the humidifier cannot start normally.

　　We know that humidifier is composed of compressor, computer board, display screen, heat exchanger, fan, water rack, shell and controller. Its working principle is: the fan draws out the moist air. If the machine does not start, what is the reason?

　　1. If the power supply fails, check whether the power supply is powered on normally

　　2. Display problem: check whether the display button reacts

　　3. Computer board problem: If the display is normal, check whether the computer board is sufficient

　　4. Humidity control problem: If the above two problems are OK, check whether the display screen displays humidity control. If the outdoor temperature reaches or exceeds the temperature we want to dehumidify, the humidifier does not start

　　5. Temperature and humidity sensor problem: check the display. If E1 is displayed, there is a problem with the temperature sensor. If E2 is displayed, there is a problem with the humidity sensor.
