Hello eray. These are not hard to change. You will need to remove the ice bucket and gain access to the ice maker. On the top of the ice maker assembly, at the front, is two screws mounting the ice maker assembly to the top of the freezer compartment. You will remove those screws and the ice maker assembly will pull back toward you and drop down. Then unplug the wire harness for the ice maker assembly. Reinstall in reverse order with the new ice maker assembly. Hope this helps.
