door makes noise when opening and closing – other than that it works fine
Very likely the noise is caused by tension on the nylon cable from the spring, as it moves around the friction pulley.
Check the cables for any grease or oil, if the cables have been lubricated replace the cable and friction pulley it rides around. This may require replacing the cable and pulley on both sides. After checking or replacing these parts take a bar of regular unscented soap and liberally rub both of the cable and the door spring on both sides. Then open and close the door 4 or 5 times to work the soap into the cable and pulley to complete repair.
