My shut off arm hits the shelf when I try to pull the freezer open. So I can't open freezer all the way without smashing the shut off arm. Do I need to cut something or buy a different shut off arm?
You will want to make sure that the ice bin is turned the proper way and that the shelf is in place properly. Also check to make sure that the screws for the icemaker are tight and the icemaker is not leaning. If this checks ok then a new shut off arm would most likely be what is needed.
