The Planetary Assembly is an OEM replacement part for Kitchenaid stand mixers. It is the central component that transmits rotational power from the motor to the mixing attachment through an intricate system of gears.

Symptoms of a bad planetary assembly include:

• Slipping or jumping of gears during mixing
• Grinding or scraping noises
• Inability to mix thoroughly on higher speeds
• Premature failure of the motor
