Amana manufactures many types of home appliances, including dishwashers, microwaves, ranges and refrigerators. Amana refrigerators have an interior light that turns on when the door is opened. The light allows you to see the contents of the refrigerator. After extended use, the light needs to be replaced. Amana refrigerators require a 40-watt appliance lightbulb, which is available at most supermarkets and home-improvement stores.
Unplug the refrigerator from the wall.
Locate and remove the light cover. Some units have a screw that needs to be removed. Other units have light covers that can be simply pulled off.
Unscrew the old lightbulb, and then install the new bulb. Ensure that the new lightbulb is the same shape, size and wattage as the old bulb.
Replace the light cover, and then restore power to the refrigerator.
