Most Frequent Causes for Vacuum cleaner motor not working Cause 1 On - Off Switch To determine if the switch is defective, use a multimeter to test it for continuity. If the on-off switch does not have continuity, replace it. Cause 2 Drive Motor First, test the power switch for continuity to ensure that the motor is getting power. If the power switch has continuity, ensure that the blower wheel turns freely and is clear of obstructions.
