Either the coupling from the motor with the fingers on it is not really attached to the motor shaft or the drive on the blade that engages with it is not attached to the blade shaft. One other thing is that on some models if the rubber jar seal between the beaker and the blade carrier is in the wrong place it can raise the blade drive to not engaging properly with the motor coupling. The gasket goes between the jar and the blade carrier, not under the blade carrier.

Hi. Our Bobby Blender jar broke and we can't find a replacement. We can part it out; do you still need the blades?

This is a common problem. This usually happens when either A) too many ingredients are added to the jar or B) the blade spokes do not sit properly in the coupling (the rubber piece). The coupling can be replaced easily. There is a great video on on how to take the coupling off as recommended by KitchenAid themselves. The part can be found at if you call them their reps are extremely knowledgeable and will be able to help you find the part in seconds. Or if you have the model number you can locate it right on their site.

Watch this video. If your jar has a lid that screws in rather than pushes in you unfortunately have to purchase a new lid, blade, gasket and collar.

Actually the drive gear was vulcanized onto the shaft during the production. If you can get glue to hold it on you're all set but I think you'll end up replacing the whole blender soon. Thank you, Dana

The piece that you need is referred to as the coupler. The coupler is a breakway part that is designed to shear and/or wear down in the event that the blender is overloaded. This is to avoid damage to the motor.

The coupler may be purchased individually and is an easy repair that can be done at home. You may purchase the part and access step-by-step replacement instructions at the following link:

The lid gasket is not available as a separate piece - an entire lid would have to be purchased. Kitchenaid still has inventory on replacement lids. If you'd like to order, you may call Kitchenaid Customer Service. Their toll-free telephone number is:


If you would prefer, you may also try MENDINGSHED.COM. They carry a large inventory of Kitchenaid parts, even if the model is out of manufacture.

to see if its the Triac or just the off button perform this: connect the blender,while pressing the off button press the on button; if the blender stays on and you dont hear the relay function (Light ticky sound) maybe the off button get a broken solder point. But if the relay is functioning and there is no way to change the speed the problen is the TRIAC. This is a small piece on PCB with a heat sink

the top rubber piece could be worn enough that it is not engaging the pitcher. look at it carefully and see if the "teeth" of the rubber disc on top of the base has not cracked and worn away. a picture of the new one can be seen on the parts websites to compare I spent $10.00 for my replacement but i found them at other sites for $6.00. you will need a very skinny 7mm open ended wrench to get the old one off and it is left handed threads that means clockwise will loosen not tighten the part.i ground down my wrench but an ignition wrench from an auto store will usually be thin enough to reach the flats on the shaft under the rubber disc
