FAQ

This coupler is designed for KitchenAid blenders, including models KSB3, KSB5, and KSB5WH.
This part replaces OEM numbers 9704230, WP9704230, WP9704230VP, and ER9704230.
The most common symptom is the motor running while the blender blades fail to spin or spin very slowly. You may also notice a burning rubber smell or visible damage, such as stripped teeth or cracks on the coupler itself.
Installation is straightforward and typically takes about 10 to 15 minutes. The included spanner wrench is required to remove the old coupler. Note that the coupler has a reverse thread, meaning you must turn it clockwise to loosen and remove it from the motor shaft.
The drive coupler serves as the essential mechanical link between the blender's motor base and the blade assembly. It transfers the rotational force from the motor to the blades; it is also designed to act as a fail-safe component that wears down or breaks to protect the motor from damage if the blades become jammed.
Ensure the blender is unplugged before starting. When installing the new coupler, hold the motor shaft steady while tightening it counter-clockwise. Do not overtighten, as this can cause the plastic threads to strip.
