Some refrigerators have the Freon line attached to the suction pipe, while others have it in their pipe. You must verify the correct configuration by consulting the manual. 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 Freon pipe. You could endanger your health by letting it leak Freon or the air. You can remove the cap by turning it clockwise to access the pipe.
This can be done with your hands. Next, wait about 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. Freon overdose can cause your refrigerator to stop working. The gauge should read 0 PSI if there is enough Freon 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. Next, check the pressure again. 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 should have ordered another tank that contains the same Freon as the 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 Freon pipe adaptor to the Freon 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.
Once Freon has been transferred to the Freon line connected to your compressor, turn clockwise to the valve on the tank replacement tank. Next, take the adaptor off the hose and disconnect it from the Freon line. Keep the cap on your adaptor, put it back, and save it for another day. 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.
Remove the screws from the back panel of your refrigerator. Take your refrigerator apart a bit, and then unplug it. Determine whether or not your refrigerator even uses Freon. To see if your refrigerator uses Freon, open the doors for the fridge and look for a metal or plastic label that contains the product information. It will list the cooling method there. There are different types of Freon. If you need to add Freon, you need to use the same kind of Freon listed on the label.
Check your vents for clogs and clean them as needed. One of the most common causes for high internal temperatures are clogs in the vents. Start by checking the vent on the back of your fridge. Then, open up the back panel in the freezer by prying it out with a flathead screwdriver to check the interior vent.
Clean up the water and see if the problem resolves itself. Usually they can be pried off with a flathead screwdriver or chisel. If your freezer is functioning poorly but the fridge is otherwise fine, your freezer coils may be frozen. Check the coils behind the back panel in your freezer to see if they have any chunks of ice on them. If the coils in the freezer are frozen, unplug the machine and let it sit for hours to defrost it.
You may need to remove the defrost drain hose from the service panel and soak it in hot water before reinstalling it. Spray a suspected leak on freezer pipes with water to see if it bubbles to find holes. Inspect the pipes in your freezer behind the panel and underneath your fridge in the back near the compressor tanks. If you see any water pooling up, clean it up and wipe the water off of the pipes. Fill a spray bottle with tap water and spray the pipes. See if the problem resolves itself before adding more Freon.
Problems with the Freon can cause other problems in your fridge. It is possible that the frozen coils, leaky pipes, or blocked vents are symptomatic of a larger problem with your Freon lines. Method 2. Get a new evaporator coil if it needs to be replaced. Usually, one of the first components of a fridge to suffer damage is the evaporator coil.
Pry out the back panel in your freezer by fitting a flathead screwdriver around the edges and popping it out. Inspect the coils to see if the evaporator needs to be replaced by looking for leaks or rust. Your coils may simply be dirty. Clean them with coil cleaning foam and paper towels if they look filthy. The dirt could be locking evaporation inside your freezer and it may be dripping down to the bottom of your fridge. Never use a different brand of evaporator coil in your fridge.
They are designed to work for specific models. Replace leaky pipes near your compressor if you want to replace the entire pipe. You can replace an entire pipe if you have access to both sides of the threading.
If you see water, check your water lines. These are the pipes running from the frame of your fridge to the supply lines. Any pipe that runs into the frame of your fridge will require a licensed specialist to replace.
Solder aluminum and copper pipes to fill in small holes and leaks. Purchase a small aluminum or copper strip, some flux, a clamp and a soldering tool. Lock your plate over the hole with a clamp and apply flux to the joint around the aluminum plate.
Use a your soldering tool to heat the joint and solder the 2 pieces together. You cannot solder any pipes with flammable materials inside them. Repair your leak or damaged parts before adding Freon to prevent additional problems. Method 3. Unplug your refrigerator and remove the screws on the back panel. Pull your refrigerator out a little bit and unplug it.
Turn it around so that you have access to the back panel, which is always at the very bottom of the fridge. Unscrew the bolts and screws with a wrench or screwdriver.
Slide the panel off and set it aside. Then, wait for about seconds before attaching the air compressor gauge to the adaptor. You would get a value for the pressure and Freon reading. An appropriate reading is important to know if you should add Freon or not. This implies that there is no pressure in your Freon line. But if it is higher than 1 psi, open the valve for about 4 to 10 seconds to let out some air. Then, check for the pressure again.
This can be done by checking the label inside or at the back of your refrigerator. If the reading you got from your gauge falls within the Freon range on the guide, then the problem may be more complicated than adding freon to your compressor. Connect this tank to the hose and then connect the hose to an adaptor on the valve attached to the Freon pipe. After transferring Freon to the Freon line attached to your compressor, turn the valve on the replacement tank clockwise.
