Our side by side fridge door sometimes "pops" open about an inch after we close it. We'll think we closed it and find it sitting open. The fridge door looks like it is about a half inch lower than the freezer door. It looks like it has dropped somehow. The paper test for the seal failed miserably on both fridge and freezer doors. We thought it was just a seal, but now I am wondering if it is a hinge problem. Any ideas or suggestions? Thanks!
