Hi thaanks for the question.
The ice maker is held on with two screws at the top of the unit.One at the front and one at the back.You just loosen them lift up on the unit It will come out
See the two tabs at the left side at the top. the screws should be there.
I will opt out .and see if another expert can help you better,.
Try Pushing up on screwdriver to push locking lever down.
Have a good night.
