What Happens when Refrigerator Door is Left Open?

Excess Moisture Formation

When you leave a refrigerator’s door open and unattended for long, the outside, warm air will combine with the cool breeze from the fridge, and the amount of moisture in the refrigerator will increase tremendously. Therefore the entire fridge will be moist, and everything in the fridge will be wet. Also, the compressor will run continuously because it is difficult for the sensors on your fridge to get to the cool temperature, resulting in more moisture in the refrigerator.

The Refrigerator will Take Time to be Cool Again

Another profound thing that will happen is that it will take a longer time than normal for the refrigerator to become cold again. It will take a defrosting process to commence before the fridge ever becomes cold again.

Food Items Get Warm, and Food Spoilage Starts

Due to the increase in temperature caused by swinging the refrigerator door open, the frozen food items getting warm, and food spoilage will begin. However, if the refrigerator was set to an appropriate temperature and remained calm, some foods like bread, fruits, vegetables will remain unspoiled. But if the foods are easily spoilt, they may get spoilt.

Your Refrigerator may Damage

Our primary concern when our refrigerator door is open is usually whether the fridge will get damaged. In some cases, the refrigerator will not damage, while in some cases, it can lead to some damages.

Electricity Waste Takes Place

When you leave your refrigerator door open for long, it leads to wastage of electrical energy. This wastage occurs because the fridge’s compressor will begin to run a cycle as you open the refrigerator.

What to Do if the Refrigerator Door is Left Open All Night?

If your refrigerator door was open all night, these are what you should do:

  • Take away every soft, wet, thawed, or leaking food.
  • Check perishable foods such as lunch meat, ground meat,  milk, fish, cooked foods carefully.
  • Check for the level of spoilage your food has gone through.
  • Throw away any food that smells or looks spoilt and has defrosted completely.
  • Check if your freezer and fridge work properly. Do that separately for proper confirmation.
  • Check for Foods You Can Save: Although some foods get spoiled when the refrigerator door is left open for hours, some foods can last for a long time without getting spoilt. The average time they can stay is 8 to 10 hours, provided the temperature does not exceed 50°F (10°C). Examples of such food include Hard cheeses, Canned fruits, Processed cheeses, Fresh, candied, dried fruits, Mustard, olives, jelly, pickles, ketchup, Butter, Fruit pastries, Sauces such as soy, barbecue, or Worcestershire, and Condiments like mayonnaise.
