The easy-to-follow instructions in this DIY repair guide explain how to replace the light switch in a top-freezer refrigerator. The light switch turns the refrigerator light on and off when you open and close the refrigerator door. The refrigerator light switch also monitors the door position for the electronic control board. If the door is open for more than 5 minutes, a door alarm sounds. If the light doesn't turn on when you open the refrigerator door or if the door alarm sounds when the door is closed, replace the light switch with a manufacturer-approved replacement part.
This basic procedure works for Kenmore, Frigidaire, Electrolux, Whirlpool, Maytag, Amana, GE, Gibson, Crosley and Haier refrigerators.
