Disposal Stopper
If your food waste disposer won’t start, check for a reset button on the bottom of the unit. If that is not the problem and your disposer 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 which 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. If the stopper does show signs of wear, you should also inspect the actuator for the switch as it may have become damaged or worn as well. Some older models use a magnetic type switch that is located at the opening of the disposer. The stopper on these models contains an internal magnet. Verify that the stopper has not become demagnetized or that the switch has become dislodged from its holder. Disconnect the power before attempting to service the disposer.
Start Switch Kit
If your food waste disposer won’t start, check for a reset button on the bottom of the unit. If that is not the problem and your disposer is a batch feed style, you may have a problem with the start switch. On most batch feed models there is a start switch located on the side of the disposer that is activated by the stopper. The stopper will have a projection or cam on it that when rotated in the drain opening, will contact the actuator of the start switch. Shut off the power to the disposer and remove the cover for the switch. Verify that the stopper is engaging the switch actuator and test the switch for continuity with a multi-meter. If the switch actuator is damaged you should also inspect the cam on the stopper as it may need to be replaced as well. Some older models use a magnetic type switch that is located at the opening to the disposer. The stopper on these models contains an internal magnet. Verify that the stopper has not become demagnetized or that the switch has become dislodged from its holder.
