I have had this problem for a year now and did the scraping by pouring warm water and pulling out the big sheet. I got so sick of always having water dripping out of the freezer. Luckily I have tile floors or I would have had to take action quicker. I found this YouTube video of an appliance repair man walking through the steps of what to do. In his video he takes the grommet(filled with gunk) and replaces it with a bigger one. I purchased a P-trap line off Amazon and will be installing that instead. It prevents the warm air from getting in and will not be able to stop it up. It appears that is the fix these companies came up with but did not feel that it was a defect and needed to be given to everyone. It was super easy to take all the parts out and my freezer will be completely ice free-hopefully! I am waiting on the part to be delivered and will let you know after the installation how it went.
