Great site! Thanks for your help with your easy Fixing a Clogged Defrost Drain Check Valve video.

Did I maybe push the grommet up too far on drain line or it seems it might be the condensate drain that requires this fix- -Fixing an Iced-Up Bottom-Mount Freezer in a Maytag-Whirlpool Refrigerator......?
