I have an Amana top freezer refrigerator and I recently measured the temperatures.
Manufacturer says 0F for freezer and 40F for fresh food.
So my freezer was -10F and fresh food about 55F
I adjusted the freezer thermostat and now the temperature is correct in the freezer compartment.
But no matter what I try, the lowest temp I get in the fresh food compartment is about 50F but nothing lower, even when I set the fresh food compartment's temp to the lowest.
The air flow appears to be fine (from freezer to fresh food) and there are no obstructions.
So my refrigerator has no problem cooling (it managed to maintain -10F in freezer compartment).
Ideas on what to check?
