I would recommend to buy two refrigerator thermometers and keep them always inside to control temperatures in the freezer and in the fresh food compartment. Normally it suppose to be about 0°F in the freezer and between 36°F to 40°F in the fresh food compartment.
Adjust the controls if needed and be advised that it takes about 24 hours to see the result.
- The part number for the refrigerator & freezer thermometer is
AP3549145
