Does leaving the fridge door open waste electricity? Many people are worried that their refrigerator uses more energy if it’s left open, but the truth of this matter depends on a few factors, such as your model of refrigerator, the time and conditions when it’s open, and how much content you have inside.
However, most refrigerator models are designed to run efficiently, even if the door remains open for long periods. In this article, we will be diving deep into this topic and help provide you with the right answers to this crucial question.
Let’s get straight into it!

Does Leaving The Fridge Door Open Waste Electricity?
Research shows that careless opening and closing of the door can lead to electricity wastes ranging from 50 to 120kWh a year. The reason? Refrigerators consume less energy while running at full capacity than they do while running at partial capacity, so every time the door is opened, the compressor stops and starts again.
When the compressor shuts off, any food in the coldest part of the refrigerator – known as zone 1 – will start to warm up very quickly. The same thing happens when it turns back on because it needs time to come up to its set temperature. These fluctuations in temperature will cause condensation and wet spots, which can drip onto other items or leak onto the floor.
A larger problem arises if you happen to be cooking with perishable foods from the freezer. Leaving the door open causes a temperature fluctuation called thermal lag in the freezer, which means things will thaw and cool down before freezing again.
Once this process begins, there’s no stopping it unless you turn off the power completely; so not only does opening the door waste energy by shutting off the compressor unnecessarily, but it also puts all your frozen foods at risk of spoiling.

Does Leaving the Fridge Door Open Damage It?
Many people think leaving the fridge door open can damage it, but this is not true. Leaving the door open will not harm your appliance. It only causes an increase in energy consumption because of the need to cool down the extra space and warm up the room after opening.
The fridge and freezer door should always be left closed while using the appliance, as this prevents heat from entering and cold air from escaping. If you are worried about forgetting to close a door before you leave home, it might be best to use a power strip or timer to turn off both appliances when you leave work or go out of town for an extended period.
You need to understand that leaving your fridge door open makes your appliance struggle to maintain the right temperature, which will make your food spoil faster than usual. Food will also lose nutrients because they cannot be preserved by freezing at sub-zero temperatures.
Does Leaving the Freezer Door Open Waste Electricity?
Yes, it does. The power to keep your freezer cold is a continuous cycle of running and stopping. When you leave your freezer door open, there is a chance that the power will stay on when it’s not supposed to. This can lead to an increase in electrical costs, which could be avoided by closing the freezer and turning it off completely.
Leaving the refrigerator door open doesn’t have any adverse effects on its overall efficiency. In fact, it might actually prolong the life of your fridge. Fridges work better when opened daily because the interior air circulates more freely. Fridges are specifically designed to handle short-term fluctuations in temperature, so leaving them open for long periods won’t harm or ruin anything inside.
Overall, leaving your freezer and refrigerator doors open won’t hurt them, but it can significantly increase your energy costs.
Can You Ruin a Fridge by Leaving the Door Open?
The compressor in a refrigerator is an important part of the cooling process. It helps maintain low temperatures by running at all times, circulating refrigerant, and regulating temperature. Leaving the door open will not completely ruin it, but it can cause damage and lead to costly repairs or replacement.
The compressor may overheat if left on for long periods. This can cause it to fail completely or shut off until it cools off.
Some sensors monitor how long the compressor stays on, and if it has been left on for too long, there’s a risk of an expensive repair or total failure. When appliances have this type of fault with them, they’re more likely to develop other faults, which could require even more work.
Is it bad to leave the fridge door open?
It is bad to leave the door open because you are not maintaining its ideal internal temperature. The longer you leave the door open, the warmer it will get in there, and food that needs to stay cold for more than a few days will spoil.
If you’re wondering how much power is wasted by leaving your fridge or freezer door open, it’s not as significant as you think.
Leaving an open refrigerator door typically wastes approximately 50 to 120kWh a year (depending on the size of the refrigerator). A freezer door left open also doesn’t use too many kilowatts per hour but can make all the difference if you’re cooking something that requires a lot of refrigerated space (like a big Thanksgiving dinner).
Conclusion
In a nutshell, leaving a refrigerator or freezer door open for an extended period will not damage the appliance but will increase energy consumption and lead to a lot of food spoilage. If you think opening the doors from time to time will save some money on bills, think again.
Besides, no studies prove this claim, so avoiding such risks as ruining your appliance by leaving the doors open too often might be wiser. You can do some research and find out how much your monthly electric bill is before deciding if this is a wise way of saving energy (or money).
