Refrigerators are need instead of a luxury. Though every refrigerator needs freon recharge after a certain period. If the cooling capacity is decreasing, you need not to panic. Perhaps your refrigerator needs only a freon recharge. The trademark for all the refrigerants is called freon in general. The name has become generic. The chemical named R-134 used as a freon since 1995. Before that refrigerator used R-12 as freon. None but a certified technician can buy R-12 these days. However, you can buy R-134 from any automobile parts shop nearby. Let us talk about the steps you should know to charge your refrigerator without making a hassle.

How to Charge a Refrigerator

Step 1: Knowing the freon your refrigerator use

You should watch carefully the back of your refrigerator. A screwdriver or a nut driver will be ideal to open up the screws. Remove the compressor cover slowly. Once you find it behind your refrigerator. Try to find the tag in your compressor. The tag will tell you which refrigerant component you need to recharge.

Step 2: Blocking the refrigerant line

A saddle valve is needed to be installed in the copper refrigerant pipe between the compressor and the refrigerator. The valve will block the refrigerant flow to the refrigerator. The valve will need two pieces to wrap around the copper pipe. You should use the hex-head screw to hold the valve in place altogether. You can use the hex-head wrench to tighten the screws which come along with the valve.

Step 3: Installing the adapter

You should install a refrigerant valve adapter to the saddle valve for the safety of your refrigerator. The adapter should create a device friendly blockage onto the valve and service port of the refrigerator.

Step 4: Connecting the hose

Some refrigerant hose kit comes along with the freon cylinder. Else you might need to buy one. Connect the hose kit along with the freon cylinder. The kit comes with a colorful gauge meter, the hose for refrigerants and thread. The thread uses to connect the refrigerant cylinder with the service port through the refrigerant adapter connected with the saddle valve. This will happen only after connecting another face of the hose with the adapter. You might use the hex-head wrench to adjust the screw to accomplish the task.

Step 5: Pressure gauge stopped going down

You will need to turn on your refrigerator after getting done with the hose kit. The refrigerator should run until the colorful gauge meter shows the pressure has stopped going down. This process might take around 3-5 minutes.

Step 6: Feeding refrigerants

Well, your refrigerator is ready to get the refrigerants. The set up is done as well. You should open the refrigerant cylinder port to convey the refrigerant into the system from the cylinder. Modern refrigerants ideally require pressure in between 25-45psi. You should close the port at the end of every minute and check the pressure. You should continue the process until you get the perfect pressure in the feedback of the gauge meter.

Charging your refrigerator is already done. You should clean up the mess and set things up before you start to use it. Close the saddling valve with your hex-head wrench. Disconnect the hose from both the end. Bring the compressor cover and place it properly. Once the placement seems perfect reinstall it with the screws.

Freon recharge in a particular period is a must for all sort of refrigerator. You can fix it on your own if you follow the steps above. You need no professionals, neither you need to panic. Stay calm and follow the method. You will get rid of your recharging issue easily.

Though older ones, especially those which manufactured before 1995 need R-12, a CFC should not be recharged without professional technicians.

How to Charge an Evaporator Refrigerator

You should open up the compressor. Install a valve to block the copper pipe. Set an adapter in the valve. Bring the hose kit and connect both the end. One with the adapter and another with the refrigerant cylinder. Keep checking the pressure gauge. Once your pressure gauge showing you a reading around 25-45psi. Remove the refrigerant cylinder. Reinstall the compressor and remove the valve along with the adapter.

How to Charge a Refrigerator Compressor

Basically, charging a refrigerator with freon means charging its Compressor. Every compressor has a tag under its movable hatch. The tag tells you which refrigerants your compressor requires. You can use a screwdriver to open the hatch cover. Read the name tag and install a saddling valve with an adapter. Connect the hose kit with the adapter and the refrigerant cylinder. Keep reading the pressure at the end of every minute by closing the port. In a few minutes, your compressor will be charged.

How Much Does it Cost to Recharge a Refrigerator
