The invention discloses a fault detection method and device for an air conditioning unit, an air conditioner and a storage medium, and the method comprises the steps that when an inner fan of the air conditioner is started to preset time, the outdoor environment temperature and the indoor environment temperature are obtained; the outdoor environment temperature and the indoor environment temperature are matched with a preset temperature interval so as to determine a current detection mode of the air conditioner; parameters corresponding to units to be detected in the air conditioner are sequentially obtained, parameters of the units to be detected are obtained, the parameters of the units to be detected are sequentially compared with the parameter interval corresponding to the current detection mode, and whether each unit to be detected is in an abnormal state or not is judged; and if it is judged that all the to-be-detected units are in the non-abnormal state, it is judged that the air conditioner units are
