Appliance Light Bulbs. When the light bulb in your refrigerator, stove, or microwave oven burns out, you have to replace it with an appliance light bulb, not a regular light bulb. Appliance light bulbs are designed to withstand both high and low temperatures as well as vibration. Never put a regular incandescent light bulb or CFL in a stove or refrigerator. That could lead to a very nasty accident!
