“What was the last thing that you put down the disposal?”
First make sure that the electrical switch is in the off position.
Is there any obstruction in your garbage disposal?
If the disposal is jammed, then you need to grab an allan wrench and, at the base of the disposal, there is a hole. Place the wrench in the hole and turn it clockwise.
Check to see if the RED BUTTON is in the OFF Position at the base of the disposal. This button is the fuse for the disposal and, if loose, it has been tripped. Push it upward and then turn on the disposal at the outlet.
