Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Washer agitates poorly or will not agitate effectively.
• Upper agitator spins freely in both directions.
• Clothes receive reduced wash action because the upper agitator is not ratcheting.
• Agitator may move intermittently or slip under load.

Check Before Replacing

• With the washer unplugged and empty, gently check whether the upper agitator rotates freely in both directions; excessive free rotation can indicate worn directional cogs, but this check is not conclusive.
• Observe whether the lower agitator moves while the upper portion fails to engage during a normal cycle; do not place hands in the washer while it is operating.
• Inspect the accessible cogs for visibly worn, cracked, or missing teeth only after following the model-specific procedure for removing the agitator.
• Confirm that the installed agitator design and model-specific parts list call for the 80040 cog set before ordering.
