We ordered a new door mullion from appliancepartspros.com on a Sunday and received it on Tuesday. The shipping speed was awesome! There are only two screws to remove on the middle bracket and one small electrical connector to unplug. After that you slide the mullion upward off of the two plastic holders on the top and bottom. The top holder was partially broken...and unfortunately you can't buy that piece separate. So I improvised and used some gorilla glue (super glue) to hold it in place and it worked great! Hopefully it holds forever. Over all it was a great experience and I'll definitely order more parts in the future. Thanks!
