what size allen wrench for garbage disposal

Most garbage disposals use a 1/4-inch Allen wrench to manually turn the motor and clear a jam. Some models use 3/16-inch , so if 1/4-inch doesn’t fit, try checking the manual or the label on the unit.

Quick fix

  • Turn off power to the disposal first.
  • Insert the Allen wrench into the hex opening on the bottom.
  • Work it back and forth until the impeller moves freely.

If yours is different

  • 1/4-inch is the most common size.
  • 3/16-inch is another common size on some models.
  • If neither fits, the safest move is to check the manufacturer’s instructions for your exact disposal model.
