Refrigerator as long as it runs out of gas

Refrigerators for long-term use may run out of gas or lack of gas is an unavoidable condition. How long it takes a refrigerator to run out of gas is difficult to predict, but only based on identifying signs such as:

- Refrigerator does not refrigerate or refrigerate for long.

- The compressor works, but the thermal switch does not stop.

- The outdoor unit is not hot, the indoor unit is not covered with snow and not cold.

Poor cold or the ability to refrigerate for a long time is a sign that the refrigerator is running out of gas or running out of gas

Gas in the refrigerator is a closed circulating system and is not destroyed, so the causes of the refrigerator running out of gas, lack of gas are often due to open pipes or joints, causing gas leaks. Specifically:

- A racket: This cause is difficult to detect because gas slowly escapes, a small amount through tiny holes and most commonly the cabinets have a long time of use.

- Open joints: When the welds are not sealed, uncertainty after a period of use will cause gas leak.

- Strong impacts: Strong impacts during transportation are also one of the common causes of gas leaks.

- Perforation: Usually because the user uses sharp objects to pry the ice or snow closed inside the refrigerator and according to the holes, the gas will escape.

How to check the refrigerator for leaks or lack of gas or not?

To check if the refrigerator gas is escaping, you can apply the following 3 ways:

Method 1: Use soap bubbles

This is the method used by many people because the implementation is quite simple. You just need to apply a sufficient amount of soap on the pipes, outdoor and indoor units and observe. If you see soap bubbles anywhere, make sure the hole is punctured.

Method 2: Based on the oil slick on the pipeline

When the refrigerator starts to show signs of less cold, you can disconnect the power, wipe the system and then reboot. Then look at the pipes, outdoor units, and indoor units, if there is oil spills, there are holes in that area.

Method 3: Use a match to identify lack of gas (absolutely do not use a lighter)

You take a match, light it, then heat it and end the outdoor unit while the machine is running. If the tube is heated, the refrigerator cannot be touched, the refrigerator is short of gas. Conversely, if the cabinet still has enough gas, after being heated, you can still touch the tube.

Types of gas used in the refrigerator

1.Gas R12

It is a gas commonly used in old refrigerators, has a bad smell, and has a dark smell when burned.

According to many studies, R12 gas contains many ozone depleting substances, so this gas is not used anymore, but instead is new gas that is safer for the environment such as R134a, Mr. 88, Mr. 86.

2.Gas R134a

Gas R134a has many physical and chemical properties similar to R12, but the substances inside do not destroy the ozone layer, so it is widely used in today's residential refrigerators. However, the biggest disadvantage of this gas is the use of polyester oil (PO), which is susceptible to moisture, causing many difficulties in repair and maintenance.

3.Gas R404

Specialized gas for extremely low temperature freezers.

4.Gas R600

Used in high-end refrigerators, Gas R600, also known as Hydrocarbon Gas, is a substitute gas for R134a because of many outstanding advantages such as helping the engine to operate smoothly because R600 is very light, ensuring cold. optimization and outstanding power saving ability.

How much money does the refrigerator cost?

Depending on the type of refrigerator, she has a gas pump capacity that has different costs
