The invention relates to a fan system monitoring method, a medium and a range hood, and the fan system monitoring method comprises the following steps: judging that the detected deviation values of the end point of a motor shaft relative to the central point of the whole range hood in the axial direction, the radial direction and the tangential direction are smaller than a first preset displacement deviation threshold value; calculating the total voltage value of the motor in each direction within the preset operation time period at the current operation rotating speed; detecting the displacement deviation values of the corresponding motor shaft end point in each direction relative to the opening center of the volute front cover and the displacement deviation values of the motor shaft end point in each direction relative to the opening center of the volute rear cover when the motor stably operates; when all the displacement deviation values are not smaller than a second preset displacement deviation threshold
