You'll find the refrigerator is (on purpose) very, very tight. For safety reasons, it has to be. Once you unscrew everything, you might find it helpful to have someone push from the back (avoiding wiring, coils, etc), as you pull from the front. Try to push/pull straight ahead. It's easy to get it wedged in place if you try to go side to side. Good luck!
