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

So, if your refrigerator compressor has divided, it'll need to be replaced. However, before you replace the compressor, you should weigh the expense of replacing it with investing in a new refrigerator. Purchasing a new refrigerator may be a better choice.

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

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

The first step would be to remove the old compressor. To do that:

Turn the power off to the refrigerator and pull the plug out.
Remove all the contents of one's fridge. Since replacing a compressor may take a long time, it will be best to place your food into coolers.
Pull the fridge out from the wall to help you access the trunk of it.

Take away the back panel of the fridge. To remove 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 is behind the fridge on underneath of it.
Disconnect the power cable, and remove the cover that protects the electrical components.
Remove the relay, the capacitor, and the overload protector.
Release the refrigerant by attaching a perforating valve onto the procedure tube and releasing it. Ensure you have adequate ventilation.
Once released, you should connect a nitrogen cylinder onto the manifold and inject the gas at a pressure of 50 PSI.
Take away the manifold valve.
Sand the compressor tubes in the areas which have been soldered so they are abrasive.
Slice the discharge and suction tubes (leave about 20-30 mm from the finish 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 need to clean the tubes. This is done by welding on a tube connector to the suction line and charging a cylinder with about 500 ml of solvent. Afterward you attach the cylinder to the suction line and attach the finish of the cylinder to the solvent cylinder. Put the tip of the capillary into a container to receive the used solvent. You can inject the solvent through the system. After that, you need to give the system a nitrogen charge to clear out any residual solvent.
Step Two. Install the New Compressor
Now that you have removed the old compressor, the next step is to install the brand new one. To do that:

Attach the brand new filter (be sure you have the correct one). You first have to solder a Schrader valve onto the extra 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 new compressor into the correct position.
Connect all the tubes up to it, and weld them on.
You should then execute 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 means that there is a leak. Once tested, release the nitrogen.
Use a vacuum pump to remove air from the compressor.
Install the capacitor to the relay, accompanied by the overload protector, and then attach the relay to the compressor`s terminal.
Connect the coolant 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 (make sure you have the right volume).
Double-check that of the wires and tubes are correctly positioned, and if so, your new compressor should now be successfully installed.
THIRD STEP. Test That It Works
The final step would be to test that your new compressor works. You are able to do that by simply 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.
