How exactly to Replace a Refrigerator Compressor
When the compressor becomes faulty, your fridge cannot operate correctly, and you also run the risk of having 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 need to weigh the expense of replacing it with purchasing a new refrigerator. Purchasing a new refrigerator may be a better choice.

Replacing a compressor is an extremely difficult repair to create and involves welding. You need to only attempt this repair for anyone who is experienced and/or a qualified technician. Additionally it is a very dangerous repair to handle, as it involves dealing with highly flammable gasses.

Here`s a step-by-step guide for how exactly 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 energy off to the refrigerator and pull the plug out.
Remove all 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 in order to access the back of it.
Remove the back panel of the fridge. To eliminate the panel, you merely need to unthread the screws that hold it in place, and it should come off. Once removed, place it taken care of.
Locate the compressor. It is at the back of 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 you have adequate ventilation.
Once released, you have to 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 that have been soldered so that 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 (work with 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 finish of the cylinder to the solvent cylinder. Put the end of the capillary into a container to receive 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 clear 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 new one. To do https://losangelesrefrigeratorrepairs.com :

Attach the brand new filter (be sure you have the correct one). You first need to solder a Schrader valve onto the extra connection (make 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 around it, and weld them on.
You should then execute a leak test by injecting nitrogen into them and using a sniffer tool. In the event that you don`t have a sniffer tool, it is possible to place soapy water onto them and appearance out for any bubbles that appear, as this means that there is a leak. Once tested, release the nitrogen.
Use a vacuum pump to eliminate 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 (be sure to have the correct volume).
Double-check that of the wires and tubes are correctly positioned, and when so, your new compressor should now be successfully installed.
Step Three. Test That It Works
The final step would be to test that 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 need to contact a technician to take a look at it.
