Customer Questions and Answers for Planetary Assembly (Silver) by Whirlpool

This silver Planetary assembly is the lower drive unit of a stand mixer that carries the beater shaft. Replacing a worn or loose planetary restores smooth, consistent planetary motion and reliable attachment rotation for dependable mixing performance.

• Transfers motor power to the beater and creates true planetary mixing action
• Houses the beater shaft and interfaces with the lower gear train
• Helps maintain stable beater-to-bowl alignment at the bottom of the mixer head
• Typical failure symptoms: beater not turning or stalling, grinding/clicking from the lower head, or noticeable wobble/excess play in the planetary

• Unplug the mixer and remove the bowl and beater before service
• Drive out the roll pin to remove the old planetary; transfer and reuse any model-specific hardware
• Clean and re-grease gears with food-grade mixer grease during reassembly, if needed
• Reinstall the planetary and pin; verify beater-to-bowl clearance per the owner's manual before use
