How to Replace a Freezer Compressor
When the converter becomes faulty, your fridge cannot run correctly, and an individual run the risk of having to throw food away.

Therefore , in the event that your refrigerator converter has broken straight down, it'll need to end up being replaced. Nevertheless , prior to you replace the particular compressor, you need to weigh the expense of changing it with purchasing a new refrigerator. Purchasing a brand new refrigerator might always be a better selection.

Replacing an air compressor is a really difficult repair to make and consists of welding. You must only attempt this fix if you are usually experienced and/or a new qualified technician. It is also the very dangerous repair to carry out, mainly because it involves operating with highly burnable gasses.

Here` s a step-by-step guidebook for how to change the compressor.

The first step? Remove the Outdated Compressor
The first step is to eliminate the old compressor. To do that:

Turn the power off to the refrigerator and even pull the connect out.
Remove all of the contents of the fridge. Since replacing an air compressor can get a long time period, it will be best to place the food into coolers.
Pull the fridge out from the walls so you may access the backside of it.
Take away the back panel with the fridge. To get rid of the panel, you just have in order to unthread the anchoring screws that hold it within place, plus it have to come off. As soon as removed, place this dealt with.
Locate typically the compressor. It is definitely at the again of the fridge on the base of it.
Disconnect the power cable, plus remove the include that protects the particular electrical components.
Take out the relay, the capacitor, as well as the overburden protector.
Release the particular refrigerant by fixing a perforating regulators onto the procedure tube and then launching it. Make sure https://refrigerator-repair-man.com have sufficient ventilation.
Once unveiled, you need in order to connect a nitrogen cylinder onto typically the manifold and put in the gas at a pressure of 50 PSI.
Eliminate the manifold valve.
Yellow sand the compressor pontoons in the regions that have been soldered thus that they happen to be abrasive.
Cut the discharge and suction tubes (leave regarding 20-30 mm in the end of the particular process tube).

Remove the compressor.
Eliminate the filter. You need to use a soldering flashlight (use a neutral flame).
If the compressor motor burned out, you will need to thoroughly clean the tubes. This is certainly done by welding over a tube plug towards the suction series and after that charging a new cylinder with concerning 500 ml associated with solvent. You and then attach the cyndrical tube to the suction line and connect the end of the cylinder to the solvent cyndrical tube. Put the suggestion of the capillary in to a container to be able to receive the used solvent. You can inject the solvent throughout the system. Following that, you need to give the system some sort of nitrogen charge to clear out any residual solvent.
Step Two? Install the New Compressor
Now that you’ve got removed the old converter, the next step is to set up the new one. In order to do that:

Attach the new filter (make sure an individual have the proper one). You first have to solder some sort of Schrader valve on the additional connection (make you need to take the cap off before welding). Next, hook up and weld the particular filter onto the condenser outlet. An individual can then affix the filter in order to the capillary tube and weld this on.
Put the new compressor to the appropriate position.
Connect most the tubes approximately it, and weld them on.
You should then do a leak test by simply injecting nitrogen directly into them and employing a sniffer tool. If you put on` t have the sniffer tool, you can place soapy water onto all of them and look out there for any bubbles that appear, as this indicates you will find a leak. Once analyzed, release the nitrogen.
Use a hoover pump to get rid of air from your converter.
Install the capacitor to the pass on, followed by the overload protector, and even then attach typically the relay to the air compressor` s terminal.
Hook up the cooling wire connections to the pass on and the excess protector terminals.
An individual can now position the electrical components include back on.
Load the compressor together with refrigerant (make sure you have correct volume).
Double-check that will all of the particular wires and tubes are correctly located, and if so, your current new compressor ought to now be successfully installed.
Step A few? Test That That Works
The last step is to be able to test that your brand new compressor works. An individual can do that will by simply switching your refrigerator again on and screening to verify that it is working. Otherwise, a person will need to contact a technician to take a new look at this.
