It is generally recommended that a fridge be turned off 24 hours before it is moved. If this timeframe is not possible, ensure you turn off your fridge a minimum of four hours before your move. This allows the fridge's evaporator time to defrost, reducing the risk of damage during a move.
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.
According to the FDA, it is not advised to eat food that's been left at room temperature for more than two hours--that's when it starts to enter the ``danger zone,'' when its temperature hovers between 40 and 140 degrees F and it can start to develop harmful bacteria.
However, your refrigerator does not—and should not—run constantly. Every 12 to 15 hours, the refrigeration defrost cycle should begin, which uses a defrost heater to melt any frost that has accumulated on the evaporator coils. Once the defrost cycle is complete, the refrigeration cycle will begin again.
That being said, you did well by keeping the doors shut. The Centers for Disease Control and Prevention tell us that food is safe in a refrigerator for up to 4 hours, in a FULL freezer for 48 hours and a freezer that is HALF-FULL 24 hours.
Refrigerated Food and Power Outages: When to Save It and When to Throw It Out. 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.
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.
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.
You should leave your fridge/fridge freezer to settle for at least 4 hours. Once 4 hours have passed, you can plug your appliance in. When doing so, make sure that the thermostat control is set to on. Before placing food into the appliance, allow your fridge some time to cool down to temperatures safe for food storage.
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.
Refrigerated foods that can be held at temperatures above 40ºF until power returns include: hard cheeses, butter, margarine, fresh fruits, fruit juice, fresh unpeeled vegetables, salad dressing, ketchup, mustard, olives, pickles, jams, jellies and peanut butter.
Bacteria can grow rapidly on food left out at room temperature for more than 2 hours. If food is left out in a room or outdoors where the temperature is 90 degrees F or hotter, food should be refrigerated or discarded within just 1 hour. Myth: When I microwave food, the microwaves kill the bacteria.
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.
Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
If you are going to be away for a month or less, we recommend the following: Leave the refrigerator running. Leave the temperature controls at the normal settings. If all the food is removed and you want to save energy, the temperature control may be set to a warmer temperature setting during the absence.
The simplest way to do this is to unplug the fridge from the power source and let any moisture, frost or ice melt and run down into the bottom of the fridge naturally. Be sure to put a towel in the bottom of the fridge first, to absorb any water that runs down.
How often should a fridge start and stop? All fridges are 'on' most of the time. And by that I mean — it is typical for a refrigerator compressor to run anywhere between 4 and 8 hours before turning 'off'. Newer models run even more frequently — about 80% of the time.
After turning off the fridge and freezer, it's crucial to give them sufficient time to settle. We recommend waiting at least 24 hours before moving. This waiting period allows the refrigerant oils to settle, ensuring optimal performance once it's back in operation.

With the fridge switched off, the temperature inside rises, so will the chances of growth of harmful bacteria. This results in the store food items getting stale and making them dangerous for consumption.
Your fridge should run from around 35% of the day to around 85% of the day. A refrigerator that gets opened more frequently has to operate more often to lower the temperature of warmer items, so this amount varies. However, no fridge should run all the time.
You depend on your refrigerator to work as intended to preserve perishable foods, keep beverages refreshingly chilled, and to freeze meats, vegetables, or frozen treats for future use. But if your refrigerator seems to be “running” all the time, then the appliance is working too hard.
Everyone wants to keep their milk fresh as long as possible, but did you know that how long your milk sits out can impact that? In general, perishable foods like milk should not sit out of the refrigerator or cooler for longer than two hours.
How long will food last in a refrigerator without power? The USDA advises that a refrigerator can keep food cold and safe for consumption for up to four hours if the door is left unopened.
To reduce Salmonella growth, eggs gathered from laying hens should be refrigerated as soon as possible. After eggs are refrigerated, they need to stay that way. A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg.
