Is there continuity through the motor?
It is a universal type motor, so the armature and fields are in series.
If there is, it could be in the speed control devices.

Are the brushes OK?

What country are you in? If it's the UK, have you checked the fuse in the plug?

Does the motor move if you change the speed. If so, then you burned a spot in the speed control.

Yes it is a Universal motor, you need to do some continuity checks, that is if you possess a meter.
