Ice building up in one corner almost always means warm air is sneaking in there. A few things to try:
- Do the dollar bill test around the gasket. Close the door on a bill and see if it slides out easily at that top left corner. - If the gasket is flattened or kinked, warm it with a hair dryer and gently shape it back out. - Make sure the door isn't sagging or twisted on its hinges. Snug up the hinge screws if needed.
If the side trim piece holding your door panel is broken, the upper door retainer 623943 fits the N621 with a smooth interior door, and it's in stock.
