Are you in need of refrigerator repair? If so, it is important to be aware of the new flammable R600a refrigerant used in most newer “sealed system” refrigerators, and the correct compressor installation process. With the right knowledge, you can ensure that your appliance is safe and functioning properly. In this blog post, we will discuss the importance of proper compressor installation and provide helpful tips for consumers needing appliance repair.

What is a sealed system?

Your refrigerator’s cooling system, also known as the refrigeration sealed system, is responsible for keeping your fridge at the proper, designated temperature.  It’s a continuous process that, when halted, causes your refrigerator to lose it’s cool.  A refrigerator that can’t stay cold can cause you a ton of problems.

There are a variety of issues that can cause your fridge’s sealed system to malfunction, including an overheated system, mechanical wear and tear, system leaks, or unwanted moisture entering the system.  The sealed system is made up of a variety of components, any of which could break down due to age, misuse, or overworking. Each component has a specific part to play in maintaining the continuous thermodynamic process that cools your home refrigerator.  Of all the appliance repair items you may have to take care of, sealed systems are among the most popular depending on the brand of your refrigerator. The cooling system within your refrigerator – also known as the refrigeration sealed system – is responsible for maintaining a consistent temperature that keeps your food fresh and safe. Unfortunately, a variety of issues can disrupt this thermodynamic process, such as an overheated system, mechanical wear and tear, so stay ahead of any potential problems.

LG Refrigerator Not Cooling Or Freezing

Failed Inverter Linear Compressor
If your LG refrigerator is not cooling in both compartments, this cooling problem is common for double door (French door) refrigerators and in 90% of cases is related to a failed inverter linear compressor and in 10% of cases to a failed start relay. If the freezer is still cold but the fridge section is warming up, this problem in 80% of cases is caused by restricted airflow, due to burnt defrost thermal fuse, defrost heating element, or failed evaporator fan.

The coming of age of R600a Refrigerant

R600a is quickly becoming the ideal refrigerant gas for domestic and small commercial refrigerators. This naturally occurring gas offers excellent thermal performance, causing minimal environmental impact with its zero ODP and low GWP. Additionally, R600a has a much shorter atmospheric lifetime of less than one year versus 16 years for traditional R134a refrigerants, making it the top choice for conservation-minded consumers.

Risks and Benefits of R600a Refrigerant

R600a is a hydrocarbon refrigerant often used in smaller appliances such as refrigerators and freezers. It is non-toxic and has a low global warming potential, making it an environmentally friendly option for repairs. However, R600a must be handled with care due to its flammability, so you may want to consider the risks before deciding on this type of repair.
