The duration for which you can safely leave your refrigerator unplugged depends on various factors, including the climate, the cleanliness of the appliance before unplugging, and the type of food residues left inside. In general, it is advisable not to exceed a few weeks.
Unplugging the fridge will NOT hurt it & will save you the cost of electricity it uses, if you are not using the fridge (don't you want cold water / food in there?).
Only completely empty your refrigerator and freezer if you'll be away from home for over a month at a time. Once it's empty, wipe down the inside with a rag and cleaning solution. Turn off the temperature controls and unplug the fridge after everything is dry. Also, turn off the ice maker.
As the USDA notes in Keeping Food Safe During an Emergency, your refrigerator will keep food safe for up to 4 hours during a power outage. Keep the door closed as much as possible. Discard refrigerated perishable food such as meat, poultry, fish, eggs, and leftovers after 4 hours without power.
Luckily, your fridge can go without power and keep your food safe for up to 48 hours, depending on the food and how it's stored. Here's everything you need to know—including when bacteria growth becomes a threat and forces you to toss perishable food.
Damages the Compressor and Rubber Seals
Prolonged periods without operation can cause the compressor to malfunction or even fail.
The doors of your fridge need to be kept open the entire time is it in storage to prevent smells and moisture building up. The best way to do this is to use a piece of cardboard or some cloth to prop the doors open. Don't use anything with a sharp end as it can cause a dent.
How long will milk/eggs last during a power outage? Milk, eggs, fish, meat and leftovers will last four hours in the refrigerator, as long as the door stays closed the entire time.
It can take about 12 hours to cool the interior down to 40℉ (the food safe recommended temperature as determined by the U.S. Food and Drug Administration (FDA). But cooling time can vary by brand and refrigerator type. With that in mind, cooling time can range from 2 to 24 hours.
Discard refrigerated perishable food such as meat, poultry, fish, soft cheeses, milk, eggs, leftovers, and deli items after 4 hours without power or 2 hours after the temperature rises above 41 °F.
If you are going away for a month or longer, it is a good idea to unplug your refrigerator to save energy. Empty your refrigerator, drain the water tank if you have one, clean the inside of the appliance and leave the doors open to avoid any unwanted odours.
Food absorbs the cold air, which helps to chill the food next to it. When the refrigerator is too empty, the appliance is working very hard (and costing you money) just to cool a few items. You may find you empty refrigerator not cold enough, or you could find delicate items (i.e., lettuce) freezing.
Turning the fridge on too soon can lead to a coolant rush, which can cause problems like leaks or blockages. This can damage the fridge, and you may need to pay for expensive repairs. Waiting allows the coolant to settle back into its correct position and ensures that there are no leaks or blockages.
Avoid mildew by propping an unplugged refrigerator's doors open with a ball of tape to give an inch or more of space. This space will allow moisture to escape. “The No. 1 thing is to get the moisture out of it,” said Stackpole.
Leaving your fridge unplugged for a long time can mess with its parts. The seals, gaskets, and inner workings can dry out, crack, or get brittle. This means your fridge might struggle to keep things cool when you plug it back in.
In general, it is advisable not to exceed a few weeks. Three important pieces of information regarding the safe duration of leaving the refrigerator unplugged are: Climate Impact: Warmer climates may accelerate the formation of odors or mold, making it advisable to keep the unplugged period shorter.
Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature. The refrigerator will keep food cold for about 4 hours if it is unopened. A full freezer will keep the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed.
You can leave milk out of the fridge at room temperature for up to two hours, according to the USDA. “Leaving milk out too long can potentially lead to foodborne illness,” Amidor explains. “Pathogenic microorganisms like to grow in temperatures between 40 to 140 degrees.
Throw away any refrigerated food that has been exposed to temperatures 40 degrees Fahrenheit or higher for more than 4 hours. Throw away refrigerated food that has an unusual odor, color or texture. Throw out perishable food in the refrigerator after 4 hours without power.
The answer is no. The temperature of a refrigerator needs to be maintained at a certain level, and if you unplug it, the temperature inside drastically changes leading to many problems. Even when not in use at night, it is best left plugged in to preserve the quality of the food stored inside.
The best way to store a refrigerator in a storage unit or for any length of time it is going to be switched off is with the doors partially opened for ventilation. This can be achieved by placing an old towel in between the door and the door frame to prevent it from completely closing, then securing in place with tape.
If the garage space is uninsulated or too cold, the freezing temperatures will trick the freezer into thinking it has reached the desired level of refrigeration and it may fail to turn on, which could result in damage to the unit and food spoilage.
If the icemaker on your Refrigerator will not be used for some time, such as during a vacation or when the appliance is placed in storage, we recommend that you shut off the water supply to the Refrigerator and turn off the icemaker.
