If the motor doesn’t rotate after press “START” button. The wire that control the motor might have
something wrong. Such as the protective tube on control board is damaged or fall off,. Or the motor
wire isn’t connected well.Or the IGBT on control board is burnt out Check if the motor wire is
connected well and re-connect well.Check if the protective tube is OK, re-set it or change one. Use
multimeter to test if the IGBT is burnt out,and change an IGBT or control board.
