Things You'll Need
The fresh food compartment in your Frigidaire refrigerator is actually cooled by the freezer compartment. The fresh food compartment has a damper installed at the top of the left wall, which allows air to pass from the freezer to the refrigerator compartment. The passage of air is regulated by a thermistor, which monitors the refrigerator temperature and dictates when the damper door opens and closes, allowing air to pass through. If the damper, thermistor or damper door is damaged, you must remove it from the refrigerator and install a new damper assembly.
Turn off the refrigerator breaker in your home's service panel.
