I installed the new freezer gasket (order #8936277) and it was as easy as your video described, but ice flows continue to form across the top of the freezer door shelf, just like they did with the gasket I removed. On a whim, I put pencils behind the tube part of the seal across the top and the ice stopped forming in the middle of the door where the largest diameter pencil was. Is that indicative of a part defect or is there another trick I should know about?
