Defrosting your freezer can help it function more effectively and save up freezer space. So how long does it take a fridge to defrost?

There is no specific time necessary to defrost a refrigerator. It might take anything from a few hours to a day or more, depending on variables such as how thick the icing ice is.

In this post, we’ll look at how long it takes to defrost a fridge on average, as well as the many elements that influence this time.

How Long Does It Take To Defrost A Fridge?

Even if huge bowls of boiling water are placed in the freezer, it may take some individuals more than 5 hours to defrost their fridge, while others may just take 3 hours.

The thickness of the ice coating on the back of your refrigerator is one of the few criteria that affect how long it takes to defrost a refrigerator; a thick ice layer means more time scraping it off and waiting for it to melt.

Always keep an eye on your fridge to ensure that the ice coating does not develop so thick that you have to wait many days to defrost it.

Factors That Determine How Long It Takes To Defrost A Fridge

How long does it take to defrost a fridge is determined by two key aspects: internal factors and external ones.

Internal Factors

The ice layer thickness is the major component that determines how long it takes for the frost in your freezer to melt.

The thicker the frost in your freezer, the longer it will take to remove it.

If you have thick icing in your fridge, it may take more than a day to properly defrost the fridge, even if the door is kept open the whole time.

However, if elements of your refrigerator, such as the defrost thermostat or compressor in self-defrost refrigerators, begin to fail, the defrost time will be extended.

A defective compressor or thermostat may cause ice to accumulate over time. If you go on a lengthy trip and have to leave your fridge running to keep items preserved, you will return to an ice-filled refrigerator if the compressor is malfunctioning.

External Factors

Some people defrost their refrigerators by just leaving the doors open. They sit down and wait for the ice, no matter how thick, to melt for hours until everything is entirely melted.

This will undoubtedly take longer to defrost your fridge; however, you may expedite the process by pouring several cups of hot water in the freezer and closing the door.

Because of the steam from the bowls, the frosting would melt even quicker, hastening the melting process.


How long does it take a refrigerator to defrost? As previously stated, this is determined by two factors: the thickness of the icing at the rear of your fridge and the technique used to melt the ice.

Defrosting your fridge is critical, and understanding how to do it correctly can save you a lot of time and trouble.
