The blender started being much louder and there is a burning smell coming out of the base. Where should I start if I want to fix it?

Should I order any parts? Or can I just maybe grease it somewhere?

Ninja Master Prep QB900B: Why won't the motor stop running when plugged in?

Mon, 10 Mar 2025 17:50:30 -0700

One day after normal use of blending, I pushed down the button to blend and then it never stopped running unless unlplugged.

I have disassembled the top motor portion and about a 1/4" diameter and 1/2" heigh spring fell out, but nothing else seemed obviously amiss.

Maybe I haven't found the right spot where the spring belongs and it had just worked loose, but I can't find a manual that shows where the spring should go.

I have tried putting the spring where the top piece contacts the bottom piece near the bottom side and near the top middle directly on the motor shaft. No luck.
