Reply To: Forgetting to close the fridge light before Shabbos

You could rewire your refrigerator so that the light stays on. I my fridge, the light is incandescent, so it gives off a lot of heat. If it stayed on, your fridge would be working overtime to negate the extra heat. Maybe some refrigerators use LEDs, where this wouldn’t be much of an issue. In any case, there are things other than the light that are controlled by opening and closing the door.
