Many Frigidaire refrigerators come with a control lock that prevents children from changing the settings and temperatures and, in some cases, restricts the use of the water fountain or ice dispenser. Unlocking your Frigidaire refrigerator enables you to use the controls and adjust the setup of your refrigerator. Older Frigidaire refrigerators do not feature a control lock.
Examine the control panel and locate the "Control Lock" button, sometimes located next to the "Light On-Off" button.
Press and hold the "Control Lock" button for a few seconds until the small red LED goes out.
Make your changes to the refrigerator's controls, or use the water and ice dispenser. Repeat step 2 to restore the control lock.
