How to adjust the speed control on your Whirlpool stand mixer

• Hold a finger next to the beater shaft to count revolutions. Start the stand mixer at stir speed.
• Count the orbital revolutions of the beater shaft for 15 seconds. At stir speed, the beater shaft should hit your finger 15 times indicating that the shaft is spinning at 60 RPM.
• If the mixer is spinning too fast, unplug the mixer and evenly rotate the control plate upper mounting screws in. Rotate the screws out to increase speed.
• After adjusting the speed, reassemble the mixer and test the speed again. Continue adjusting and checking the speed until the mixer runs at 60 RPM at stir speed.
• Once the correct stir speed is set, unplug the mixer and tighten the jam nuts on the control plate upper mounting screws. Reinstall the end cover and restore power.

Troubleshooting your Whirlpool stand mixer when its shaft isn't spinning

A failed worm wear or damaged planetary gear assembly can prevent the beater from spinning. If the beater doesn't move at all when the motor spins, then the worm gear is likely stripped. Unplug the mixer, examine the worm gear and replace the gear if it's stripped.

If the beater moves around the inside of the mixing bowl but the beater itself doesn't spin, then the pinion gear inside the planetary gear assembly is likely stripped or damaged. Unplug the mixer, pull off the planetary gear assembly and replace the assembly if the pinion gear is damaged or stripped.
