Hi thanks for the question.
Does the fan work in the freezer /
Can you feel frost on the freezer wall ?
Send me the model # XXXXX
Freezer fan working, freezer items all still frozen.
Model # XXXXX 25.0 cu. ft.
And no frost on the freezer wall ?If no frost on the freezer wall.
Pull the fridge out from the wall and check the coils at the back by the compressor.
If the coils have dust bunnies on them it will cause this problem.
