The drive motor and gear kit operate the trash compactor press which helps compact the trash. When in use, the drive motor will activate the press, by turning the gears and a chain, that will lower into the trash, compact it and then raise back up. If your compactor is noisy or not compacting you may need to replace the motor. This kit includes the motor, drive gear, jumper harness, and is a genuine OEM part. Please remember to disconnect the power to the trash compactor before starting the repair.
