Self Closing Fresh Food door doesn't

The fresh food door on my Ge fridge doesn’t self close anymore. I checked the drawings and I see a cam avilable to replace the original, but when I check the door itself while opening it, I can see the door rising on the cam and it appears to rise just as much as the freezer door that does self close. Also the unit is not out of level and the doors line up with equal spacing, so it is not out of square. What else sould I look for?
