The kitchen door cabinet holding your garbage pail on the sliding brackets may refuse to close. If that is the case, start by removing the drawer and shimming the bottom to make it level. Also, put a level on the drawer glide on each side of the cabinet and check both sides. You will also need to look at the soft-close accessories. If they are not working properly, remove the soft-close piston assembly, put back the drawer and try. Lastly, check if the floor in front of the cabinet is level. If not, it needs to be repaired.
