Your disposal can jam if something
solid or tough gets lodged between the spinning plate and the
inside wall of the disposal. There aren't many parts of your garbage
disposal that you can or should service yourself, so be sure to
call a service professional for any repairs your disposal may
need. Never get your hands near the opening while it is running.
TIP: To reduce odors and freshen your drain smell, try grinding a lemon rind into your disposal.
