How To Defrost A Frost Free Freezer?

 It may sound unusual, but often your frost-free freezer may require defrosting. Therefore it’s crucial to understand “How to defrost a frost-free freezer?”

Are you concerned about defrosting a frost-free freezer? Don’t worry; we have the best instructions and simplest procedure to assist you in defrosting your freezer quickly and easily!

All refrigerators and freezers may produce ice, but frost-free appliances make this ice on an evaporator, a form of radiator concealed by an insulated panel typically at the top or back of the cavity of the freezer.

 Your frost-free freezer may need an hour or a day to defrost thoroughly. It can even require you to wait longer than 24 hours to eliminate the frost from some freezers with thick ice.

Stay with us through the end to understand more about how this defrosting procedure works!

How to defrost a frost-free freezer?

It is crucial to remove the ice because, over time, a buildup would prohibit the freezer from defrosting. After all, the air wouldn’t be able to pass this evaporator.

The timer circuit turns on a heater connected to the evaporator in a functional frost-free freezer to melt and clear the ice while simultaneously turning off the compressor. The compressor starts up again, and the cycle is repeated immediately as the freezer recognizes that the ice has been removed.

The water produced by the melting ice drains into the appliance’s back, where heat from its compressor will cause the water to evaporate.

A thorough defrost may initially solve this issue, but if it keeps happening, it may result from a fault. In rare circumstances, the ice might not entirely melt, obstructing airflow.

When defrosting a frost-free freezer:

As previously said, any ice will probably be behind the insulated panel, so clearing it will take some time. Professional engineers advise removing all the food and containers from your freezer and leaving it off with the door ajar for at least 36 to 48 hours to give the ice time to defrost.

This is based on the assumption that the surrounding temperature is 50 °F (10 °C) or higher; if it is cooler, defrosting your freezer may take even longer.

By using a bowl of warm water and shutting the door, or by using a steamer, you might be able to accelerate the defrosting process. Avoid using heat guns, though, since they can easily harm the cavity’s lining.

We’ll look briefly at what enables frost to accumulate in freezers, how to fast defrost your refrigerator before going into how long the process takes, and what factors affect the duration.

Let’s begin right away.

The cause of frost formation

The evaporator coils in your freezer are where the majority of the frost that you see forms. The refrigerant is transformed into cold gas by the evaporator coil. Therefore, this gas keeps your refrigerator cool as it passes through the coils.

Here are a few things that can build up ice in your freezer or refrigerator.

(1) Due to Humidity

The evaporator coils of your freezer will become covered in frost if warm air is allowed inside. Thanks to the auto-defrost fan, you may keep moisture out of your freezer if you don’t open it for too long. However, if this fan is broken, you should be prepared for ice to begin to accumulate in your freezer quickly. The air entering your refrigerator rapidly solidifies on the coils if you frequently reopen the freezer door. There will be a greater likelihood of a frost formation if this occurs often.

(2) Due to an insufficient amount of refrigerant

Many people are unaware that the amounts of their refrigerant might not be optimal. And the refrigerator has issues as a result. Why does this matter?

Low refrigerant levels might cause the compressor to wrongly compresses the refrigerant, resulting in warm gas rather than cold gas passing over the coils. Meanwhile, liquid refrigerant leaks into the coils when the refrigerant is in excess.

(3) Due to Malfunctioning of Compressor 

Since you use a frost-free freezer, you believe that frost will never form in your freezer.

I’m sorry to let you down; this is not accurate.

In a self-defrosting freezer, any accumulated frost drips into a pan at the bottom. But your freezer will eventually become frosty if the compressor isn’t working.

Additionally, some freezers have a defrost regulator to prevent ice accumulation. The freezer’s interior temperature is controlled by the defrost thermostat.

How long does it take for a Frost Free Freezer to Defrost?

If you expect your freezer to survive a long time, you must regularly defrost the freezer. Your refrigerator runs the danger of having a short lifespan if you don’t perform this simple but irritating operation.

You can defrost your refrigerator’s freezer for any amount of time. Some users took longer than five hours, even after putting big bowls of heated water in the freezer. While it just took three hours for some people. 

It takes a bit of thick ice to claim that your freezer has frost and that you must perform some defrosting procedures. So, unless you want to remove a little layer of ice from the back of your freezer, you might need to invest some time.

What Elements Affect the Amount of Time Needed to Defrost a Frost free Freezer?

The time it takes to defrost a freezer mainly depends on internal and external factors.

Internal Variables

The size of the ice is the primary internal element influencing how long it requires for the frost inside your freezer to melt.

 It will take some time to eliminate it if it is incredibly thick. Even if you keep your refrigerator open at that time, it can take longer than a day for it to defrost entirely.

Additionally, defective refrigerator components like the compressor or defrost thermostat in frost-free freezers will prolong the defrosting process.

External variables

Some individuals leave their refrigerator doors open to allow the interior to defrost. They wait hours until everything melts, no matter how thick the ice is.

You would also concur that defrosting your refrigerator freezer will take longer than when numerous bowls of hot water are placed inside with the door closed. The steam emanating from those bowls would speed up the melting process.

Your refrigerator freezer needs to be defrosted in two processes. They comprise the stages of preparation and carrying out. Let’s take a quick look at the procedures:

Clean out the freezer

It is totally up to you to decide how you want to clear the contents of your freezer. If you only have a few dribbles in your freezer, you might choose to consume those items when the time for defrosting draws near. However, if you have many products in the freezer, you might need to put them in a container with ice to keep them from spoiling. The more space you have in your freezer, the simpler it is to eliminate all the ice.

Unplug the freezer

It’s not a good idea to leave your freezer on while it’s defrosting:

If your freezer is on, it will continue to run, and you might never thoroughly remove the frost. There is just so much time you can waste. This might cause the coils of the refrigerator to create ice.

Place a towel or a container at the bottom of the freezer

Once you defrost your refrigerator, there will be a huge water pool in your freezer. To stop leaks and keep your floor tidy, put some old rags in the bottom of the freezer. You would collect the melted ice water in these old towels and trays. If the ice is thick, you might need to press these clothes and remove the water later.

Remove the Shelves

In some freezers, the frost can also build up to the point where it covers the freezer shelf surfaces. To make things easier in this situation, you must remove the shelves. Keep calm if the shelves become jammed. Keep them there until some of the ice has melted.

Be sure to leave the door open after removing the shelves. Defrosting will take considerable time if the door is closed during the operation.

Remove a small amount of the ice

Your refrigerator’s frost will clear up quickly if you scrape some ice. To utilize the proper tool, you must be highly cautious. If not, you risk harming your refrigerator’s interior parts. You must use a plastic scraper or the defrosting tool with your freezer or refrigerator. Avoid scraping your freezer with objects made of glass or metal.

Use hot water to melt ice

As we have already discussed, defrosting a freezer with hot water is a pretty widespread practice. This does not imply that you should pour hot water into your freezer.

Prepare several bowls of water to put on the shelves or at the bottom of the freezer to speed up the defrosting process.

But make careful to lock the door after putting the bowls of hot water inside the freezer.

The water will quickly become cold; therefore, you’ll need to recheck the freezer frequently. Therefore, refill the bowl with hot water after 5 or 10 minutes. You can use the scraper to remove additional ice from the freezer’s walls.

Clean your freezer

You’ll have to clean your freezer after properly disposing of the ice, water from the tray, and used towels.

Right after defrosting, it is ideal for cleaning the entire refrigerator. To accomplish this, wash the shelves with soap before rinsing them with fresh water. Additionally, wipe every water drop from your freezer with a new cloth. After that, let it dry completely before connecting it back in.

How can you avoid the formation of frost in your frost-free freezer?

The following are some different things you can do to stop frost from accumulating in your refrigerator:

  • Limit how frequently you open the freezer.
  • Don’t fill your refrigerator too full.
  • Check for leaks in the door.
  • Set the temperature of your freezer.
  • Avoid putting warm or hot items in the freezer.


Defrosting a refrigerator freezer can take a few hours, a day, or more. The amount of ice and the equipment you use to defrost your freezer will often determine how long it takes to defrost.

In the meanwhile, you can stop the freezer and refrigerator from getting frosty. You can achieve this by looking for leaks, adjusting the freezer’s temperature, and placing the proper number of objects within.

With that said, make sure to maintain proper refrigeration for your freezer. Additionally, since the production of frost has the potential to harm your freezer, it is advised to remove it as often as you can.
