How to Keep Your Fridge at the Right Temperature
The first thing you want to do is store food correctly. That way, even if your refrigerator warms up, you and your family will be safe. Store perishables in the back and use the fridge’s door only for condiments and jars, not the milk or the eggs.
Store a gallon of water in your fridge. It’s a great way of having a refreshing drink in hand, and it will keep the fridge’s overall temperature low.
Don’t over pack your fridge. To keep the temperature nice and low you need airflow, and too much stuff won’t help with that. The same goes for your freezer.
For health-sake, store your cooked food on the top racks and the raw food at the bottom. Any dripping from raw food could contaminate your leftovers with disastrous results. That’s how restaurants do it, so it’s good for you too.
