The freezer part of the refrigerator in my kitchen is warm and I've come to realize the coils are quite dusty. But Maytag (and, I guess, Whirlpool) freezers don't have flat coils that I can easily brush or vacuum off. They are sort of W shaped with the trough going across the width of the fridge so I can only really see the leading edge of the first "fold."
I found one suggestion of using a compressor to blow off the coils then clean up the dust behind but that seems to have only really affected the first section. Another suggestion was to empty the fridge and tip it or lay it back and clean from underneath. I hate to think about that but I'm out of ideas. Anyone here smarter than me? :-)
