Disposal Stopper

If your garbage disposal won’t turn on, troubleshoot the problem by hitting the reset button. If that doesn’t make it start working, there may be an issue with the disposal stopper. This is applicable to batch feed style models. On this type of model, the stopper activates the start switch via a projector or cam which rotates and comes in contact with the start switch. If this part is damaged, it may not make full contact with the start switch actuator, meaning your disposal won’t turn on. Turn off power to the unit and check the stopper and actuator for any signs of damage. If your model has a magnetic switch, make sure it is still magnetized. If any of these parts are damaged, they will need to be replaced.

Start Switch Kit

If your garbage disposal is not working or won’t turn on, try hitting the reset button which is usually located on the bottom of the disposal. If the reset button doesn’t make the disposal turn on, there may be an issue with the start switch kit. Batch feed style garbage disposals have a start switch which is activated when it comes in contact with the stopper. To check the functionality of the start switch, first shut off power to the unit. Remove the switch cover, located on the side of the disposal. Make sure the stopper is properly aligned so that it comes in contact with the switch. Check the switch for continuity using a multi-meter. If the switch actuator or stopper cam are damaged, they will need to be replaced. Some garbage disposals have a magnetic switch; check to make sure it has not been demagnetized.
