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 divided, 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 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 exactly to replace the compressor.

Step One. Take away the Old Compressor

The first step is to remove the old compressor. To achieve 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 would 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 eliminate the panel, you merely have to unthread the screws that hold it set up, 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 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 process tube and releasing it. Ensure you 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.

Take away the manifold valve.

Sand the compressor tubes in the areas which were 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 (work with a neutral flame).

If repair refrigerator compressor burned out, you will need 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 end 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 machine. After that, you need to supply the system a nitrogen charge to clear out any residual solvent.

Step Two. Install the brand new Compressor

Now that you have removed the old compressor, the next thing is to install the brand new one. To do that:

Attach the new filter (be sure you have the right one). You first need to solder a Schrader valve onto the extra connection (be sure you take the cap off before welding). Next, connect and weld refrigerators repair 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 appearance out for just about any bubbles that appear, as this indicates there exists 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.

Now you can put the electrical components cover back on.

Fill the compressor with refrigerant (make sure you have the correct volume).

Double-check that all 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 certainly do that by simply 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.
