Tips on how to Replace a Refrigerator Compressor When the automotive compressor becomes faulty, your fridge cannot function correctly, and an individual run the risk of having to throw foodstuff away. So , if your refrigerator automotive compressor has broken down, it'll need to become replaced. Yet , ahead of you replace the compressor, you should weigh the cost of replacing it with buying a new fridge. Purchasing a brand new refrigerator might end up being a better alternative. Replacing a compressor is an extremely difficult repair in order to make and entails welding. You need to only attempt this repair if you are experienced and/or a qualified technician. That is also the very dangerous fix to carry out, since it involves working with highly inflammable gasses. Here` t a step-by-step guide for how to exchange the compressor. The first step? Remove the Outdated Converter The 1st step is to be able to remove the old air compressor. To accomplish this: Turn the particular power off to be able to the refrigerator in addition to pull the put out. Remove each of the contents of the fridge. Since upgrading an air compressor can get a long time, it might be best to place your meals directly into coolers. Pull the fridge out from the wall membrane so you can easily access the again of it. Take away the back panel of the fridge. To eliminate the panel, a person just have to be able to unthread the anchoring screws that hold it within place, and it need to come off. As soon as removed, place it aside. Locate typically the compressor. It will be at the back again of the chiller on the bottom part than it. Disconnect the power cable, in addition to remove the protect that protects typically the electrical components. Get rid of the relay, typically the capacitor, as well as the clog protector. Release typically the refrigerant by attaching a perforating device onto the process tube and then launching it. Make certain you have enough ventilation. Once launched, you need to be able to connect a nitrogen cylinder onto the particular manifold and utilize the gas at a pressure regarding 50 PSI. Take away the manifold valve. Fine sand the compressor pipes in the locations which have been soldered thus that they will be abrasive. Cut refrigerator repair service and suction tubes (leave concerning 20-30 mm from the end of the particular process tube). Remove the compressor. Get rid of the filter. You may use a soldering torch (use a neutral flame). If the particular compressor motor burned out, you will have to clean the tubes. This is done by welding on the tube connector towards the suction range after which charging some sort of cylinder with concerning 500 ml regarding solvent. You after that attach the canister to the suction line and add the end regarding the cylinder to the solvent cyndrical tube. Put the idea in the capillary straight into a container to be able to receive the applied solvent. You could inject the solvent from the system. Right after that, you will need to supply the system the nitrogen charge in order to out any extra solvent. Step 2? Install the New Compressor Now that youâve got eliminated the old automotive compressor, the next step is to set up the brand new one. To be able to do that: Affix the new filtering (make sure an individual have the appropriate one). You 1st have to solder a Schrader valve upon the additional connection (make be certain to take the cap off just before welding). Next, link and weld the filter onto the particular condenser outlet. A person can then affix the filter to be able to the capillary tubing and weld it on. Put the fresh compressor in to the right position. Connect most the tubes approximately it, and welds them on. You need to then do the leak test by simply injecting nitrogen straight into them and applying a sniffer tool. If you put on` t have some sort of sniffer tool, an individual can place soapy water onto them and look out and about for any pockets that appear, while this indicates we have a leak. Once tested, release the nitrogen. Use a hoover pump to get rid of air through the automotive compressor. Install the capacitor to the relay, followed by the overload protector, and even then attach the relay to the automotive compressor` s terminal. Connect the cooling wire connections to the exchange and the excess protector terminals. A person can now position the electrical components include back on. Fill up the compressor along with refrigerant (make confident you hold the proper volume). Double-check of which all of the wires and pontoons are correctly positioned, and if so, your own new compressor ought to now be efficiently installed. Step About three? Test That This Works The final step is to be able to test that your particular fresh compressor works. An individual can do that will by simply converting your refrigerator again on and assessment to verify that it is definitely working. If not, you will need in order to contact a tech to take some sort of look at this.
