How To Repair Washing Machine Drum

When the compressor in your refrigerator fails, it won't work properly, and you'll have to toss food away.

As a result, if your refrigerator compressor fails, it must be replaced. However, before you replace the compressor, compare the expense of doing so to the cost of buying a new refrigerator. It's possible that buying a new refrigerator is a better option.

A compressor replacement is a demanding repair that necessitates welding. This is a repair that should only be attempted by experienced and/or qualified technicians. It's also a risky repair to do because it entails working with extremely combustible gases.
The following is a step-by-step tutorial to replacing the compressor.

Step 1: Disconnect the old compressor.

The old compressor must be removed first. To do so, follow these steps:

Remove the refrigerator's plug and turn off the electricity.

Remove everything from your refrigerator. Because repairing a compressor might take a long time, storing your food in coolers is the best option.

To get to the back of the fridge, pull it away from the wall.

Remove the refrigerator's rear panel. To remove the panel, just unthread the screws holding it in place, and it should fall loose. Place it out of the way once it's been removed.
Track down the compressor. It's on the bottom of the fridge in the back.

Remove the cover that protects the electrical components and disconnect the power cable.

Remove the overload protector, the relay, and the capacitor.

Attach a perforating valve to the process tube and then release it to release the refrigerant. Make that you have enough airflow.

After the gas is expelled, attach a nitrogen cylinder to the manifold and inject it at a pressure of 50 PSI.

Remove the valve from the manifold.

In the regions where the compressor tubes have been soldered, sand them to make them abrasive.
Disconnect the suction and discharge tubes (leave about 20-30 mm from the end of the process tube).

Remove the compressor from the equation.

Remove the filter from the equation. A soldering torch is required (use a neutral flame).

You'll need to clean the tubes if the compressor motor burns out. This is accomplished by attaching a tube connection to the suction line and then filling a cylinder with 500 ml of solvent. The cylinder is then connected to the suction line, and the end of the cylinder is connected to the solvent cylinder. Place the capillary's tip into a container to collect the used solvent. The solvent can be injected into the system.
Step 2: Put the New Compressor in Place

After you've removed the old compressor, it's time to put the new one in place. To do so, follow these steps:

Put the new filter in place (make sure you have the correct one). To begin, solder a Schrader valve to the additional connector (make sure you take the cap off before welding). Connect the filter to the condenser outlet and weld it in place. After that, you may solder the filter to the capillary tube.

Install the new compressor in the proper location.

All of the tubes should be connected to it and welded on.
Then, using a sniffer tool, do a leak test by injecting nitrogen into them. If you don't have a sniffer tool, you can put soapy water over them and watch for bubbles, which indicate a leak. Release the nitrogen when it has been tested.

To remove air from the compressor, use a vacuum pump.

Connect the capacitor and the overload protector to the relay, then connect the relay to the compressor's terminal.
Connect the cooling system wires to the overload protector terminals and the relay terminals.
You may now replace the cover over the electrical components.
Refrigerant should be added to the compressor (make sure you have the correct volume).

Check that all of the wires and tubes are in the proper places, and if they are, your new compressor should be ready to use.
Step 3: Verify That It Works
The final step is to make sure your new compressor is operational. You may accomplish this by just turning on your refrigerator and evaluating its functionality. If not, you'll need to get in touch with a professional to get it looked at.
