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 price of replacing it with investing in a new refrigerator. Purchasing a new refrigerator may be a better choice.
Replacing a compressor is a very difficult repair to create and involves welding. You should only attempt this repair if you are experienced and/or a professional technician. It is also an extremely dangerous repair to carry out, as it involves working with highly flammable gasses.
Here`s a step-by-step guide for how to replace the compressor.
Step One. Remove 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 the contents of your fridge. Since replacing a compressor may take a long time, it could be best to place your meal into coolers.
Pull the fridge out from the wall so you can access the trunk of it.
Take away the back panel of the fridge. To eliminate the panel, you merely have to unthread the screws that hold it set up, also it should come off. Once removed, place it out of the way.
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 process tube and releasing it. Make sure you have adequate ventilation.
Once released, you need to connect a nitrogen cylinder onto the manifold and inject the gas at a pressure of 50 PSI.

Sand the compressor tubes in the areas which 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 should employ 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. 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 right into a container to receive the used solvent. It is possible to inject the solvent through the machine. After that, you will have to give the system a nitrogen charge to drive out any residual solvent.
Step Two. Install the brand new Compressor
Now that you have removed the old compressor, the next step is to install the new one. To do that:
Attach the brand new filter (make 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 new compressor in to the correct position.
Connect all the tubes around 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 appearance 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 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 cooling system wires to the relay and the overload protector terminals.
Now https://squareblogs.net/peneye2/how-to-reset-a-refrigerator-compressor can put the electrical components cover back on.
Fill the compressor with refrigerant (be sure you have the right volume).
Double-check that all of the wires and tubes are correctly positioned, and when 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 certainly do that simply by turning your refrigerator back on and testing to see if it's working. If not, you will have to contact a technician to take a look at it.
