How to Check the Thermostat on a Frigidaire Refrigerator

  Place the refrigerator thermometer inside the cabinet, and wait for a few hours for the reading to stabilize. Suitable thermometers are available from most hardware stores that carry refrigerator and freezer accessories.

  Compare the reading on the refrigerator's thermostat with the reading on the thermometer. The temperatures should be a close match, within one or two degrees of each other, or else the refrigerator thermostat could be defective. Dial-controlled models should run at 37 degrees Fahrenheit too; select a different setting if the temperature is too high.
