The refridgerator door of my

Question

The refridgerator door of my Whirlpool side by side refridgerator/freezer is not closing properly. I checked for any obstructions including possible deterioration of the magnetic strips. It acts like the door may some how be sprung. It feels like resistance when I try to get it to close, but no obstructions. Is it possible to replace fittings or a sprung door?
