Whirlpool refrigerator with upper frost-free freezer compartment
Okay, so a month or so ago I had a similar problem. I took everything out of the freezer and gave it a good cleaning. I had way too much stuff in there, so I threw out quite a bit. At the time, I could feel cold air coming through the freezer vents. I also cleaned the coils under the refrigerator and inspected the door seal. There were no cracks or gaps, etc. So I reloaded the freezer and made sure the air vents were not blocked. A couple of weeks ago, I noticed the frost starting to build up on the top front area. This would be the area directly in front of the door when it is closed. I now have large frosted icicles accumulating in this area.
The food in the freezer is frozen and the refrigerator compartment keeps food cold. How can I tell if the fan needs to be replaced? How do I access the fan compartment? If it turns out that the fan is not the problem, the only other offender I can suspect is the door seal. However, I'm reluctant to consider the seal as a first option because it looks good and makes a tight seal all around when the door is closed.
