what is a refrigerator sealed system (cooling system)?

All refrigerators, from the high tech ones to a small mini-fridge to a wine cooler basically use the same type of setup to keep cold things cold. They all have a refrigerator sealed system made up of a compressor, condenser, evaporator, capillary tube, and a suction line.

When everything works properly, the liquid refrigerant flows through the right parts of the system at the correct rate and pressure. Your refrigerator absorbs heat from warm food and does its job. It also removes moisture. As long as the refrigerator sealed system stays sealed and running properly, you have cold food.

food poisoning danger

Far more people experience food poisoning every year and then become victims of refrigerant poisoning. Perhaps the biggest reason you shouldn’t put off scheduling a refrigerator repair is the need to keep groceries at the correct temperature.

Food bourne illness

The FDA estimates there are around 48 million people who get sick from food borne illnesses every year. Food poisoning happens when infectious organisms like bacteria, viruses, and parasites get on food and multiply, then people ingest them.

food poisoning prevention

One of the best ways to prevent and control the spread of those organisms is to keep food cold while you store it. Health officials recommend putting food in the refrigerator within two hours of receiving it and quickly chilling it to 3 C or below. Keep frozen foods at -18 C.

If your food can’t stay cold because you need refrigerator sealed system repairs, it goes bad faster, and eating it could make you sick. Minimize the risk by calling for our expert repair services.

FAQ Section

A refrigerator "sealed system" is also referred to as the cooling system.

  • The compressor compresses gas (refrigerant) and pumps it into the condenser.
  • The process of compressing heats the gas.
  • The hot gas is above room temperature, so the air flowing over the condenser coils cools the gas, causing it to condense into a liquid.
  • The heat coming off the condenser is either blown out the front or rear of the refrigerator, depending on the model.
  • From the condenser, the liquid refrigerant passes through a small diameter tube called a capillary tube.
  • The capillary tube slowly meters the liquid refrigerant into the evaporator where it evaporates to produce the cooling effect.
  • The refrigerant gas is then drawn out of the evaporator through a tube called the suction line by the compressor. This is a continuous process.

If your refrigerator isn’t cooling, you’re probably already wondering if it’s worth the hassle to call an appliance repair tech. You don’t want someone who wastes your time and money on trial and error. That’s one of the best reasons to hire a company that comes with more than 6 years of experience and the right tools to do the job. Our appliance techs are trained to use sophisticated equipment to give a definitive diagnosis of any refrigerator sealed system failure that exists. That takes paying close attention to details, gathering the right readouts, and often the ability to braze copper.

You might see an appliance sale advertised and wonder if you’d be better off fixing your old refrigerator or just buying a new one. That’s a good question, and one we often help customers evaluate. The answer in your situation depends on a number of repair vs. replacement factors:

  • What’s wrong with your refrigerator? Sometimes the problem is relatively minor and the fix is easy. New refrigerators are expensive, and not all of them are guaranteed to last. It’s a good idea to talk to a refrigerator repairman to find out what you’re looking at.
  • How much did your refrigerator cost to begin with? If you got it secondhand for pocket change, it might not be worth paying to repair it. However, a lot of our customers have newer refrigerators with expensive technology and high-end features. They cost thousands of dollars, so it makes much more sense to make repairs that cost a few hundred dollars or less.
  • What’s the age of your refrigerator? Experts say most refrigerators last between 10 to 15 years, depending on the brand and how you take care of it. If your fridge is past middle age, you might start to think in terms of replacement.
  • How do that brand and style hold up? If you look up your refrigerator model and see a lot of complaints about that one, in particular, it might be that a simple repair will fix a known issue. Or, you might need to think about buying a better brand.
