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

So, if your refrigerator compressor has broken down, it'll need to be replaced. However, before you replace the compressor, you need to weigh the price of replacing it with investing in a new refrigerator. Purchasing a new refrigerator might be a better choice.

Replacing a compressor is an extremely difficult repair to create and involves welding. You should only attempt this repair in case you are experienced and/or a qualified technician. Additionally it is an extremely dangerous repair to carry out, as it involves dealing 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 is to remove the old compressor. To do that:

Turn the power off to the refrigerator and pull the plug out.
Remove all of the contents of your fridge. Since replacing a compressor can take a long time, it will be best to place your meal into coolers.
Pull the fridge out from the wall so that you can access the back of it.
Take away the back panel of the fridge. To remove the panel, you merely need to unthread the screws that hold it in place, and it should come off. Once removed, stick it out of the way.
Locate the compressor. It is at the back of the fridge on the bottom 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. Be sure to have adequate ventilation.
Once released, you should 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 finish of the procedure tube).

Remove the filter. You should employ 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 then charging a cylinder with about 500 ml of solvent. You then attach the cylinder to the suction line and attach the end of the cylinder to the solvent cylinder. Put the end of the capillary into a container to get the used solvent. You can inject the solvent through the machine. After that, you will need 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 step is to install the brand new one. To do that:

Attach the brand new filter (make sure you have the correct one). You first have 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. After that you can attach the filter to the capillary tube and weld it on.
Place the brand new compressor into the correct position.
Connect all of 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, you can place soapy water onto them and look out for 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 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 (ensure you have the correct 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 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 need to contact a technician to have a look at it.
