  If the Ninja blender's motor doesn’t start or the attachment doesn’t rotate, ensure the container is securely placed on the motor base and the lid is correctly positioned. Verify the appliance is turned 'On' by pressing the power button and that the plug is securely inserted into the electrical outlet. Also, check the fuse or circuit breaker. If the unit has overloaded or overheated, unplug it and wait approximately 15 minutes before using it again. Make sure the unit is not overloaded.

  If you cannot achieve snow from solid ice in your Ninja blender, avoid using ice that has been sitting out or has started to melt. Use ice straight from the freezer. Begin with a few pulses and then switch to a continuous blending cycle.

Why won't the motor base of my Ninja Blender stick to the counter?
- A
  afreemanSep 4, 2025
  If the motor base of your Ninja Blender won’t stick to the counter or tabletop, make sure the surface and suction feet are wiped clean. Note that suction feet will only stick to smooth surfaces and will not adhere to wood, tile, or non-polished finishes. Do not attempt to use the appliance when the motor base is stuck to an unsecure surface.
