Why is my ANDELI MCT's fan not turning on, even though the power light is on?

If the power switch indicator is on but the fan isn't turning (or stops after a few rotations) and there's no welding output, it could be due to several reasons. One possibility is an incorrect connection to a 380V power supply, which triggers the overvoltage protection. Try reconnecting to an AC110V\220V power supply and restarting. Unstable AC110V\220V power or a long input line might also cause overvoltage protection; try increasing the wire diameter of the grid input line or fastening the input line node. You could also wait 2-3 minutes before restarting the device. Additionally, ensure the wires between the switch and power board are tightened and that the 24V power supply and relay are checked.
