What does it mean when the light goes off in the fridge?
If your refrigerator light is not coming on, it may be that the bulb has reached the end of its lifespan and has burned out. Check the bulb to see if it has a dark area in the bulb or has a broken and loose filament. Unplug your refrigerator, change the bulb, and it’s likely that this will solve this problem.
Why is a light bulb warm after it has been on for a few hours?
