KitchenAid Blenders - Recent Questions, Troubleshooting & Support
Blender blade not turning, rotating piece on base not connected
this is getting more and more common there is a part between the motor and the drive gear that snaps for no reason . its job is to snap if the blades jam as a "fuse" to save your house from a overheating ,jammed motor . the problem is there are no parts to buy to fix this . if its new take it back to where you bought it . otherwise shipping it 2 ways for repair to the factory is sometimes as much or more as a new blender ........ i would recomend you do one of two things : go to a goodwill or other type shop and get a nice vintage blender , it will last forever ! or move up to a vita mix . its costly but it will realy last you ... this new made in china junk is just bad news even when it has the kitchen aid name on it . its still the same junk ..... good luck........ Please if this answer helped , please rate this 3 or 4 stars . and keep
me in the paid answer department . A 1 or 2 may knock me down into the
unpaid ranks. Thanks Cactus Bob .
Melted Coupler
I'm not familiar with that model number but if it is rubber with fingers sticking up then a large flat screwdriver under it and lever it up, bending it a little from 2 different sides and you should then be able to unscrew it (left hand thread I think) with your fingers. Failing that put in extra effort and wreck it off, the threaded part is aluminum and not strong enough to cause any damage to the motor shaft.
If the coupling is internal splines in a hole ask me another question.

Pitcher stuck on base
You will likely need to replace the beaker anyway, the drive which is now melted to the motor coupling is only supplied as part of the beaker/blade assembly. You will also need a motor coupling.
Why does Kitchenaid blender KSB655 have burning smell during operation?
If it is not something to do with the coupling (rubber one on the jug bottom and hard plastic one on top of the motor) then I'd be checking that the cutter shaft is not getting hot. If it was the motor playing up normally they pop into error and stop with flashing lights. The switch panels give very little trouble.
I have a kitchen aid
The motor windings have failed. It needs the motor replaced, so it will need to go to a repair center near you. You can find all the information you need from their website.
The coupling is worn and needs to be replaced. I
I drill a hole in the outer rim of the old coupling and then using a hammer and punch in the hole whack it in the same direction it turns when the motor is running. That will eventually unscrew the coupling and you will be able to screw the new one on. There is no need to make a big effort to tighten the new coupling up hard, over time it self tightens with use, that's why you are having trouble undoing it. Just screw it up as far as it wants to go by hand.
Leaking kitchen aid blender
Make sure that the big black nut under the jar is tight. It holds the blade and bearing assembly into the beaker. The odd one can leave the factory not properly tightened up and vibration loosens it off. Nobody is telling you it will be easy to tighten that nut up because it isn't.
