when you open the freezer door and hold the light button in does the fan start? also is the frost on the back panel in the freezer section? look real good,
Here is the model info again
Make: FrigidaireModel: PLFU1778ES2
The fan was running and when I pushed in the button it contiued to run. There is no frost at all and even bread that was frozen solid is soft. usually I would hear a vacum sound upon shutting the door and when you tried to open it right away the suction was too tight to even open right away. Now it doesn't suction close at all.
