How to replace the gear case in a top-load washer

This step-by-step washer repair guide explains how to replace the washer gear case in a common style of top-load washing machine.

The washer gear case:

  • Drives the impeller that agitates the clothes during the wash cycle.

  • Rotates the spin basket in the spin portion of the cycle.

  • Shifts the drive system between the agitation and spin modes.

If the gear case doesn't drive the impeller or spin basket properly, replace it with the manufacturer-approved washer part.

Use the steps in this guide to replace the washer gear case in Kenmore, Whirlpool, Maytag and Amana top-load washing machines.

    If the status lights don’t blink, turn the control dial one complete rotation counterclockwise to reset the control and then try again, this time turning the knob faster.

    In the diagnostic mode, select the Calibration Cycle by turning the control dial 4 clicks clockwise. When the Rinse light turns on, press Start to begin the Calibration Cycle, which runs for 2 to 3 minutes.

    When the Calibration Cycle ends, the lid unlocks and the washer shuts off.
