Start Switch Kit

If your food waste disposer won’t stay running and it is a batch feed style, you may have a problem with the start switch. On most batch feed models there is a start switch that is located on the side of the disposer which is activated by the stopper. The stopper will have a projection or cam on its base that, when rotated in the drain opening, will contact the actuator of the start switch. Shut off the power to the disposer and then remove the cover for the switch. Remove the switch assembly and inspect the actuator for damage. If the switch actuator is damaged or worn it may not keep the switch closed and the disposer may not stay running. You should also inspect the cam on the stopper as it may need to be replaced as well.

Stopper

If your food waste disposer won’t stay on and is a batch feed style, you may have a problem with the stopper. On some batch feed models, the stopper is used to activate the start switch that is located on the side of the disposer. The stopper will have a projection or cam on its base that when rotated in the drain opening, will contact the actuator of the start switch. If the cam is worn or damaged it may not properly engage the switch actuator and the disposer may not stay on. If the stopper does show signs of wear, then you should also inspect the actuator for the switch as it may have become damaged or worn as well. Disconnect the power before attempting this repair.
