We have Maytag wide by side #MZD 27666EW 5 1/2 years old. The freezer door will not shut all the way. I can push it & it will stay shut, somewhat. Any ideas before I have to call a repairman?

Somehow the door hinges got out of whack. Check them to see if there is a screw coming out of the hinges.

After checking that all of the screws in the hinges are tight you might want to consider if the door has warped. You will probably need assistance to do this.

The outer metal portion of the door is thin and quite flexible. The inner plastic liner is what enables it to keep it's shape.

Remove the door from its hinges.

Lay it on a large flat surface. That is most often the floor.

Lay it lay flat with the outside on the floor. You may have to remove the handle for it to lay completely flat. Use a sheet or blanket on the floor to prevent scratching.

Underneath the rubber seal are screws that attach the inner lining to the metal outside. Lift the edge of the rubber seal and loosen all of the screws. You don't have to remove them just loosen about one or two turns. After loosening all of the screws go back and retighten then.
If the outer frame has warped, loosening the screws will allow the outer frame to go flat again. Tightening the screws will enable the linier to keep it in that position. You may not me able to discern any movement but this should make the door flat again and allow it to seal.
