Ordered new door seals (gaskets) from Appliance Parts Pros. I was able to replace the freezer door seal without taking the door off the refrigerator. (Note: this is an over/under type refrigerator, with the freezer section on top) However, the first attempt at replacing the refrigerator door seal without removing the door from the fridge did not go well as the door appeared "warped" after I reassembled it and would not come close to sealing when I closed it. When I took the door off the fridge and laid it on a flat surface (table) to replace the gasket and reinstalled the door, it closed and sealed perfectly. It was also much easier to access the bolts that secure the inner door and the seal, and to align the seal, with the door removed from the unit. Not a difficult job at all.
