frost build up on bottom of ice maker and ice park in door

HI. First make sure that the ice door is closing and is not damaged. If damaged you will need a new separator.The manufacture of your refrigerator has came up with some revisions to your current ice chute separator to correct the issues you are having with the frost build up in the ice door chute and the bottom of the ice maker. Those revisions include Creating clearance between ice door fin and inner ice chute, increase ice door minimum opening clearance and modify ice door gears to improve ice door seal. Remove the User interface by inserting a screw driver in to the two slots
to release the tabs. One on each side of the UI. The UI will pull down and away from door. Disconnect the electrical connection to the UI and set aside. Remove 4, ¼” hex screws. Push inward on two side tabs and pull dispenser
door assembly out. Disconnect the electrical connections and remove wires from plastic clip on dispenser door assembly. Remove a portion of the inner ice chute to give clearance for the fin on the back side of the ice door. Depth of cut should be approximately 5/16”. Do not cut on the outer door seal surface. Now remove the micro switch. Bend the switch arm at a point in line with the edge of the switch. Bend the switch arm to approximately a 30 degree angle and
put switch back in place. The switch should engage now before the door is fully open. Remove the 3 rear teeth from the ice door mechanism one at a time. Smooth the area down where the teeth were removed if needed. Now the ice door with have a snap sound when it closes and will seal better to prevent your frost build up. This will be much easier with pictures. I am working on including/ attaching pictures as well.
