How exactly to Replace a Refrigerator Compressor
When repair refrigerator compressor becomes faulty, your fridge cannot operate correctly, and you run the risk of experiencing to throw food away.

So, if your refrigerator compressor has broken down, it will need to be replaced. However, before you replace the compressor, you should weigh the price of replacing it with purchasing a new refrigerator. Investing in a new refrigerator might be a better choice.

Replacing a compressor is an extremely difficult repair to make and involves welding. You need to only attempt this repair should you be experienced and/or a qualified technician. Additionally it is an extremely dangerous repair to handle, as it involves working with highly flammable gasses.

Here`s a step-by-step guide for how to replace the compressor.

Step One. Take away the Old Compressor
The first step would be to take away the old compressor. To achieve that:

Turn the power off to the refrigerator and pull the plug out.
Remove all the contents of your fridge. Since replacing a compressor may take a long time, it could be best to place your food into coolers.
Pull the fridge out from the wall so you can access the back of it.
Take away the back panel of the fridge. To eliminate the panel, you just have to unthread the screws that hold it in place, also it should come off. Once removed, place it taken care of.
Locate the compressor. It really is behind the fridge on underneath of it.
Disconnect the energy cable, and take away the cover that protects the electrical components.
Take away the relay, the capacitor, and the overload protector.
Release the refrigerant by attaching a perforating valve onto the procedure tube and then releasing it. Be sure to have adequate ventilation.
Once released, it is advisable to connect a nitrogen cylinder onto the manifold and inject the gas at a pressure of 50 PSI.
Remove the manifold valve.
Sand the compressor tubes in the areas that have been soldered so they are abrasive.
Cut the discharge and suction tubes (leave about 20-30 mm from the end of the process tube).
Remove the compressor.
Remove the filter. You need to use a soldering torch (use a neutral flame).
If the compressor motor burned out, you will have to clean the tubes. That is done by welding on a tube connector to the suction line and charging a cylinder with about 500 ml of solvent. You then attach the cylinder to the suction line and attach the finish of the cylinder to the solvent cylinder. Put the end of the capillary into a container to get the used solvent. It is possible to inject the solvent through the system. After that, you will have to supply the system a nitrogen charge to drive out any residual solvent.
Step Two. Install the brand new Compressor
Given that you have removed the old compressor, the next thing is to install the new one. To do that:

Attach the new filter (be sure you have the correct one). You first need to solder a Schrader valve onto the excess connection (be sure you take the cap off before welding). Next, connect and weld the filter onto the condenser outlet. You can then attach the filter to the capillary tube and weld it on.
Place the brand new compressor into the correct position.
Connect all the tubes up to it, and weld them on.
You should then do a leak test by injecting nitrogen into them and using a sniffer tool. If you don`t have a sniffer tool, it is possible to place soapy water onto them and look out for just about any bubbles that appear, as this indicates there is a leak. Once tested, release the nitrogen.
Work with a vacuum pump to eliminate air from the compressor.
Install the capacitor to the relay, followed by the overload protector, and attach the relay to the compressor`s terminal.
Connect the cooling system wires to the relay and the overload protector terminals.
You can now put the electrical components cover back on.
Fill the compressor with refrigerant (be sure to have the correct volume).
Double-check that of the wires and tubes are correctly positioned, and when so, your brand-new compressor should now be successfully installed.

Step Three. Test That It Works
The final step is to test your new compressor works. You can do that simply by turning your refrigerator back on and testing to see if it is working. If not, you will have to contact a technician to take a look at it.
