Well, it's been a month, but...
Use your meter set for ohms to check for continuity of the power cord with the vacuum unplugged. You'll need to remove the filter bag and disassemble the handle and motor cover to get to the power switch wiring. You should have continuity all the way to the motor on both of the power wires when the switch is on. The switch will be on the "hot" wire, probably black in color. The white wire is the common, and should have continuity to the motor terminals regardless of switch position.
If the above checks out OK, and the motor is silent when plugged in, then you have a fried motor. You may do a voltage check(carefully) to verify your continuity tests, but the unit will move quite a bit if it should start while you are testing disassembled. If the impeller moves a bit or the motor hums a little when powered on, you may have something jammed in the impeller.
I have one of these units. Motor has lasted 6 years in mine, but the impeller nut occasionally works loose and causes a terrible wailing.
