Blender Parts - One Small Part Is Usually All That Stands Between You and a Working Blender

When your KitchenAid blender motor runs but the blade barely spins, the jar vibrates without actually blending, or you notice a burning smell coming from the base during operation, the blender itself is almost never finished - a worn or shattered drive coupling is the culprit in the majority of cases. It's a small plastic component that takes the full torque of the motor and transfers it to the blade, and it's designed to wear out before the motor does. At BlueStars Parts, we carry the most common blender parts for KitchenAid blenders in single, 2-pack, and 4-pack options, so you can fix the actual problem quickly and keep a blender you already like running for years longer.

Common Signs You Need These Parts

If your blender isn't performing the way it used to, a worn drive coupling is almost always what's behind it:

• The motor runs but the blade spins slowly, inconsistently, or not at all
• You can hear the motor working but ingredients aren't being blended
• The jar rattles or vibrates excessively during operation without actually moving contents
• A burning or plastic smell comes from the base of the blender during use
• The drive coupling is visibly cracked, chipped, or has broken into pieces at the bottom of the jar
• Blending performance has gradually declined over months of regular use
• The blender works briefly then slows to a stop mid-cycle
• You had to replace the coupling recently and it's already showing wear again
