LG Mini Refrigerator Compressor Installation
Make that you have all the necessary tools. You will need, at the absolute least, to have the following:
- Fresh compressor. Use the same model or, at the very least, a replacement approved by the manufacturer.
- Refrigerant. Although your refrigerator may use a different refrigerant, we use Forane 134a for this task. The name of the refrigerant is listed on a tag that can be found inside or at the rear of your refrigerator.
- Refrigerator pressure gauge with two valves
- Vase pump
- Scale of refrigerants
- tools for brazing, soldering irons, and flux

LG Mini Refrigerator Compressor Installation -Preparation
The compressor is situated at the bottom of the refrigerator’s rear in LG models. You may need to remove your refrigerator from the wall or counter to access the rear.
We already know that our compressor is broken and needs to be replaced now. The area needs to be set up to install a new compressor. Cut the pipework, remove the clamps from the compressor’s bottom side, and remove the refrigerant from the system.
LG Mini Refrigerator Compressor Installation -Take out the defective compressor
To be able to pull out the compressor as well, you will need to remove or replace the filter dryer. Remove the compressor carefully, not damaging any of the tubings. Sand the connectors down if necessary; brazing is a delicate process, and mistakes can be challenging.

Replace the Compressor with the New One, then Braze the Joints
Before igniting, insert the compressor and filter dryer and check that the joints fit snugly. It works well because we use flux-coated tin solder rods for joints with higher steel grades and silver solder rods for copper junctions. You can complete the flaming using two distinct rods in a single motion.
When you finish, check the joints again to ensure they are tight, and then begin vacuuming.
The compressor should be vacuumed
Before adding refrigerant, it is vital to vacuum the sealed system to get rid of any air and moisture. Connect the central tube to the vacuum pump and the high and low sides to your manifold gauge.
The pressure should be allowed to build up to 30 inches of mercury, which is as close to zero as we can get before you turn on the vacuum pump.

Fill It With Refrigerator Gas
You will need refrigerant scales to track how much gas is to be put into the system and the refrigerant cylinder. Although we use 134a here, your refrigerator may use a different gas. The placard inside this refrigerator states that 4.76 ounces of refrigerant are needed. Since some refrigerant will be discharged anytime you connect or disconnect the line, we usually add an extra quarter.
LG Mini Refrigerator Compressor Installation -Turn on the refrigerator
Normally, it takes a minute or two for the compressor to operate when the refrigerator is turned on.
As the compressor starts up, it’s critical to monitor the pressure change; at this point, you might wish to remove the high side and measure the charge on the low side. Since the high side pressure will cause an excessive over-release, the low side gauge, which is more sensitive to refrigerant levels, will over-release. There will be a gradual decrease in pressure. Due to the variable speed of the linear compressor, it takes 10 to 15 minutes to reach its maximum speed.
While you watch for a while, get the house in order! In 4-5 hours, the refrigerator ought to begin to cool.
Today’s post shows how to install a Mini LG Refrigerator compressor. Hopefully, this post will be of some use to you.
