Can a Refrigerator be Recharged — 5 Easy Step!

A refrigerator is an appliance for our house. An appliance without which we cannot lead our life happily.


It is expected that your home appliances lose their power at a time. But luckily, most refrigerators can be fixed with the help of some tools and a cylinder full of freon. So recharging your refrigerator is to save both your time and money.

Recharging a refrigerator will give you enough time to replace your current refrigerator with a new one. That is even if you need to buy one. Recharging your refrigerator could also save the environment instead of throwing away the refrigerator.

Can a Refrigerator be Recharged

Yes, a refrigerator can be recharged. There are five major steps in this. Firstly, remove foodstuff from the fridge, locate the compressor, and freon recharging point onto it. Then, with a Vaccum pump, suck out all existing freon, fill the tank with fresh freon, and close the intake valve.

Commonly, you face difficulties with your refrigerator sooner or later, but there are quick solutions.

Below are the 5 steps to recharge your refrigerator quickly.


Firstly, remove all the food stocks from your refrigerator. This will make it easier for you to work on your refrigerator. If your refrigerator is in a trickier situation to work with, move the refrigerator and make enough space to work around your refrigerator. 


Now you need to locate your refrigerator’s compressor. The position of the compressor is at the bottom of the backside of the fridge. You can quickly locate it because of its cylindrical shape. A compressor is an important part of the refrigerator. So don’t try to mess with it without knowing where to work. 


Now locate the valve where you will be adding freon. It would help if you had a tool for doing this. You will need a vacuum pump that you can hire from a shop. All you need to do now is to attach 5he vacuum pump and open the valve. 


Use the vacuum pump to vacuum out all the remaining freon. Removing the old freon is important as it can overfill the compressor. The last thing you would want is a freon leak into the refrigerator and your room where the refrigerator is kept. 


Connect the hose of the cylinder to the compressor valve. Check if it is connected properly. Use a wrench to connect to tighten it up before removing the freon inside the compressor. When done, close the intake valve of the compressor. 

How to Add Freon To Your Refrigerator 134a

Adding freon is a difficult task to achieve. Too much, too little, or the wrong freon can permanently damage your refrigerator.

So firstly, make sure that the problem behind your refrigerator is because of the freon shortage. Below are the steps you need to follow to ensure no damage happens to your refrigerator.

Determine if your Refrigerator Uses Freon

Since freon is dangerous to the environment after 2010, many manufacturers stopped using freon inside their refrigerators. But there are a good number of refrigerators that still run on freon. So make sure if your refrigerator uses freon or not. The easiest way to do that is to open your refrigerator door and look for a label with product information. 

Check the Vents of Your Refrigerator

One of the main causes of high internal temperature is vents being blocked by dirt and debris. Check the vents at the back of your refrigerator. You can even open the back panel of your refrigerator with the help of a screwdriver to take a peek at the interior vents. If you see them dirty, use a thin, clean cloth to remove the dirt and debris. Then, start your refrigerator and see if the problem is solved. 

Inspect Those Freezer Coils

Check to see if there is any chunk of ice at the back of your refrigerator where the coils are present. If the coils are frozen, unplug your refrigerator and wait for 24-36 hours for your refrigerator to defrost. 

Leaks on the freezer pipes

Inspect the pipes of your refrigerator behind the back and under your fridge near the compressor tank. Take a spray bottle and fill it up with water. Next, spray water on the pipes and look for bubbles. Use soldering to cover those holes or replace them with new pipes if you find bubbles.

Check if the problem is solved

Now that you’ve done the above methods, check to see if the temperature inside your refrigerator is fine. With the issues fixed like your vents, coils, and water lines there should be no need to add freon. If the issue is not yet solved, you might need to add freon.

The below steps will guide you through adding more freon in your refrigerator without causing any problem.

Unplug the refrigerator

Unplug the refrigerator and pull the refrigerator back. Rotate the refrigerator as it will make it easier to work behind the refrigerator. Use a screwdriver or a wrench to open the refrigerator. Remove the bottom panel of your refrigerator.

Locate the freon pipe

You will find the freon pipe behind the back of your refrigerator at the bottom part. The pipe should be connected to the compressor tank. A compressor compresses hot air and makes it cool before sending it inside the refrigerator. Freon helps the most in this scenario.

The freon gas is used to make the air cool fast. Find the correct line to refill freon gas. If there are multiple pipes connected to the compressor, look into your refrigerator’s manual to find the correct pipe.

Mount a Bullet piercing valve on the freon pipe

There are 2 steps to install a billet piercing valve. First, open the 3 nuts using an allen wrench. Wrap the bullet piercing valve around the pipe. A bullet-piercing valve will make a hole on the pipe. This hole will allow everything inside the pipe to escape through the valve. This will save you from the trouble of removing the pipe. 

Connect the conversion valve

You can easily access the pipe without opening the pipe using a bullet piercing valve. All you need to do is unscrew the cap. Next, twist the cap in an anti-clockwise direction until it loosens up. Now connect the conversion valve at the position where the cap was. 

Attach the gauge

Plug in the refrigerator to run your compressor. Wait for 10 to 15 seconds and check on the pressure gauge to see the pressure and freon reading. You must use a compressor gauge designed to check freon inside a compressor. You can buy one or rent from a hardware shop. 

Check the gauge reading

Any reading between 0 and 1 should be fine. Next, check the meter needle and make sure the needle is around 0. 

Connect the freon tank

Now that everything is done for the main event it is time to refill with new freon gas. Purchase a freon tank that has the exact specification that matches your compressor.

Insert freon from the hose connected to the bullet piercing valve. Screw off the line by twisting it clockwise. Now open the top valve to let go of the excess freon from the pipe.

How Do you Know if your Refrigerator is Low on Freon?

Suppose you cannot sleep because of your loud refrigerator. In that case, it could indicate that your refrigerator is running low on freon. The job of a compressor is to supply cool air into the refrigerator to keep stocks safe.

So the compression needs freon to make its work easier. Without enough freon, the compressor makes loud and consistent noises. Because now it needs to work more to produce cool air. So if your refrigerator is making loud noises and it isn’t very pleasant, check if your refrigerator has enough freon.

Another possible way to find this is to notice the temperature inside the refrigerator. If you find that your refrigerator is not producing enough cool air and your food stocks are getting spoiled very fast, this could indicate that there could be a freon leak or shortage. 

FAQs: Related Question

Q1. What if I Put too Much freon in the Refrigerator?

Adding freon more than what is declared to could overpressure the freon pipe. Or the freon gas will leak from the pipe and spread in that particular room where the refrigerator is kept. Freon is a dangerous gas, so spreading it in your room could harm you. But don’t worry, it is not life-threatening until this happens quite frequently. 

Q2. How Much Does it Cost to put Freon in a Refrigerator?

It will cost you about $200-$300 to replace the freon gas in your refrigerator. However, it is not the only way to get this job done. Freon leaks are common and can be solved by almost everyone. With proper instructions and help from some videos online even, you can put back freon in your refrigerator.

Q3. Can I use Automotive r134a in a Refrigerator?

Even though R-134A is a non-toxic refrigerant, you cannot use it as a refrigerator coolant. It is completely designed for an automotive AC, and such gas cannot be used in refrigerators due to the pressure difference.


A refrigerator has become an important part of our life nowadays. So it must be taken care of. Any unusual behavior of the refrigerator must be noted and must be solved as soon as possible.

Since such problems could permanently damage your refrigerator, the freon leak and the shortage are common problems. If not solved, it could permanently damage your compressor.
