How to Add Freon to Your Refrigerator Compressor – Step by Step Procedure

Remove and empty your refrigerator.

  • First, disconnect your fridge from the AC socket.
  • Transfer perishable food from the fridge to a cooler with ice.
  • Turn your refrigerator upside down to see the back panel.
  • Use a tool to take off the back panel’s nuts and screws.

Locate Your Compressor Tank

Freon pipes are usually located around the compressor tank.

The compressor tank is large and can be found near the bottom of your fridge.

This should be the first thing that you see when you open the back panel.

Freon should not be fed to any other pipes than the pipe.

For this purpose, refer to your refrigerator manual.

Some refrigerators have the line attached to the suction pipe, while others have it in their pipe. You must verify the correct configuration by consulting the manual.

Insert A Bullet-piercing Valve Around The Freon Line

The bullet-piercing device has three nuts. Use a wrench to unlock them.

Wrap the valve around the Freon line near the compressor. This valve will allow you to access the pipe without having to puncture it.

Importantly, make sure the valve is tightly fitted around the pipe. Use your wrench to tighten it if it isn’t. You could endanger your health by letting it leak Freon or the air.

Your bullet-piercing valve should be removed.

There’s a cap on the side of your bullet-piercing device.

You can remove the cap by turning it clockwise to access the pipe. This can be done with your hands.

Attach your conversion valve to where the cap was once you have removed it.

Next, secure it.

Get A Reading

Plug your fridge back into the socket to get Freon readings from your compressor

Next, wait about 10-15 seconds before attaching your air compressor gauge to an adaptor. The Freon and pressure readings will be displayed.

You will notice that Freon levels are on the blue side of the gauge. This means that there is still Freon in your compressor.

It is crucial to get the right reading to determine if Freon should be added. An overdose can cause your refrigerator to stop working.

Check The Pressure

The gauge should read 0 PSI if there is enough in the refrigerator. This means that your Freon line is not under pressure. It should give a value between 0 to 1 psi. This is normal. If it’s higher than 1psi, you can open the valve for 4-10 seconds to release some air. Next, check the pressure again.

Find Out How Much Freon You Need

Find Out How Much Freon You Need

You can check the label on the refrigerator’s back or inside for this information. Freon specifications should not be used for another refrigerator.

If your gauge reading falls within the Freon range indicated on the guide, it could be more serious than just adding freon.

You may wish to escalate the problem to the manufacturer or an expert in this situation.

Connect Your Freon Tank To The Adaptor

You should have ordered another tank containing the same one on your refrigerator label. The tank will also come with a flexible hose. The tank should be connected to the hose. Next, connect the pipe adaptor to the hose. Make sure the hose fits on the adapter valve and the replacement tank.

Open the valve at the top of the replacement tank to add Freon. Some tanks have gauges that show how much Freon you are releasing. Others don’t.

Try to release within your Freon levels.

Close The Valve

Once the Freon has been moved to the Freon line that leads to your compressor. Turn the tank replacement clockwise until you reach the valve. Next, take the adaptor off the hose and disconnect it from the line.

Keep the cap on your adaptor, put it back, and save it for another day. The bullet-piercing valve is already in your pipe, so it can’t be removed again.

Finally, screw the back panel in place. Plugin your refrigerator to check if it is working. This video will show you how to add Freon to your compressor.


Adding More Freon To Your Fridge

1. Remove the screws from the back panel of your refrigerator. Take your refrigerator apart a bit, and then unplug it. It is located at the bottom of the fridge. Use a wrench or a screwdriver to loosen the bolts and screws. Slide the panel off, and then set it aside.

You can store food in a cooler filled with ice if it is prone to melting or going bad quickly.

2. Look for the compressor tank to locate the Freon pipe. The compressor tank is located behind the panel in the fridge’s bottom. It cools and compresses hot air before putting it back in the fridge.

The line will connect directly to the tank and feed into your fridge. You can consult the manual of your fridge to identify which Freon line is connected to each pipe.

  • Every fridge has a different arrangement of mechanical components. Your fridge’s make/model will determine the location of Freon lines.
  • Some fridges will have the line added to their suction lines. It will be separate from other models.
  • Freon is almost always made of copper.

3. Install a bullet-piercing device around the line next to your compressor. There are two parts to the bullet-piercing device. Use an Allen wrench to unlock the three nuts and wrap the pipe around the compressor.

An adaptor can be used to connect the two pieces. The bullet-piercing VA punctures the pipe, and the contents pass through the valve. Access the pipe without removing it.

  • Two adaptors are included with the bullet-piercing device. Choose the one that best fits your tube.
  • A bullet-piercing valve can be purchased at a hardware or refrigeration store.
  • Use an Allen wrench to tighten the valve.
  • Warning! The valve must be securely attached to the pipe. You can bleed Freon and air over time if your connection is not tight. This could pose a risk to your health. If you damage the valve accidentally or incorrectly install it, consult a professional.

Remove the cap from the bullet-piercing device

4. Remove the cap from the bullet-piercing device and attach the conversion valve. To access the pipe, you will need to remove the cap from your bullet-piercing device. Turn the cap counterclockwise to loosen it.

The cap should be removed without the use of any tools. The cap can be removed by screwing the conversion valve onto the opening.

It looks similar to an air valve on a car’s tire.

5. To get a reading, plug in the fridge. To activate the compressor, plug your fridge back into power. After waiting about 10-15 seconds, attach the adaptor to the compressor gauge to obtain a Freon and pressure reading.

A compressor gauge that is specifically designed for refrigerators will be required. Rent or buy one at a hardware or refrigerator repair shop.

  • The compressor gauge must be able to read levels and pressure. To provide two different readings, it should have two gauges.
  • Freon is abundant if it is located in the blue section.

6. Make sure the pressure gauge is reading below 0 psi. Contrary to popular belief, your system should have a pressure of 0 psi. The line is compressing air by sucking it in.

If the fridge is operating, the Freon or suction lines should not be pressurized. You can check the pressure gauge to ensure the needle is at or close to 0 psi.

  • You’re good if the needle is above 0 but below one psi.
  • If your system pressure is greater than one psi, you can bleed it out by opening the valve and not attaching anything. Continue this procedure for between 4 and 10 seconds, then retest the valve.

how much Freon you will need

7. Refer to the label on your fridge to determine how much Freon you will need. You can find level on the label inside your freezer or fridge.

Cross-reference your gauge reading with the label because each fridge or freezer model differs. It should be added if the gauge reports a reading below the threshold for your fridge.

  • If the Freon reading is within the fridge’s label, call a repairman. It supply or lines are not the problems.
  • This is the exact label you used to check if your refrigerator uses Freon.
  • Sometimes, the label can be found on the backside of the refrigerator.

8. Connect the tank to your recharge hose, and then plug the adaptor into the hose. Fill a replacement tank with the same type as your label.

  • Freon comes with a hose that can be connected to your bullet-piercing adaptor. The hose can attach the Freon to the valve by twisting each fitting clockwise. To release, turn the valve counterclockwise.
  • Freon must be used in the same way as it is listed on your refrigerator’s label. There are several options: R-12, R-13B1, R-22, and R-410A, R-502 and R-503.
  • Freon tanks that have gauges can be used to determine how much Freon is being released. If it doesn’t come with one, you will need to experiment to find the right Freon levels for your tank.

9. Remove the adaptor and close the bullet-piercing valve. Turn the cap on your tank clockwise to tighten it. Next, take the adaptor from your Freon tank and remove the hose. To close the valve, put the cap back on. To close your fridge’s back, screw the panel on the other side.

Once you have installed the bullet-piercing device, it is impossible to remove it. You will have a hole in your supply or suction line if you do.
