I want to thank you for supplying the disassembly pics and instructions. I posted a comment a new section to the trouble shooting guide. In my case my eldest son used our Nutribullet in a non-pulsed way and appeared to have burned out the motor. I used your diagrams to disassemble and then - having had some experience with these issues in the past, assumed that the heat sensor had failed. Was quite frustrated when replacing this component did not fix the unit. Perseverance and some electric motor DIY channel browsing - caused me to investigate the brushes and commutator - this was the problem and a relatively easy fix as the unit was still disassembled.
