Q:

How does a refrigerator condenser work?

A:

The condenser on a refrigerator removes heat from a gas coolant and condenses it into high-pressure liquid. Coolant evaporates at low temperatures and low pressure but condenses at high temperature and high pressure; because of this, heat can be transferred from inside the refrigerator to the room. The coolant is contained in a closed system, so the process can be repeated.

The principles of refrigeration are as follows: liquids absorb heat when they are changed to a gas, and gas gives off heat when it is changed to liquid. The refrigerant enters the compressor as a low-pressure gas, where it is compressed and exits as a high-pressure gas. This gas flows to the condenser, where it is condensed to a liquid, and its heat escapes into the surrounding air.

The pressurized liquid then moves to an expansion valve, which limits the flow of the fluid and reduces the pressure of the gas as it exits the expansion valve. The low-pressure gas is then piped into the evaporator and absorbs heat, which changes it from a liquid to a gas.

As a hot gas, the refrigerant then moves to the compressor, where the cycle is repeated. The low-pressure gas is turned into a high-pressure gas and then condensed to a liquid, and so on.

  • Q:

    How does a refrigerator work?

    A:

    The cooling process in a refrigerator is accomplished through a cooling agent known as a refrigerant, which circulates through the refrigerator via a series of coils. There, it changes between two forms: liquid and gas. As the refrigerant evaporates, it absorbs the heat, which is then released into the external environment, thus cooling off the air contained in the refrigerator.

    What are some Frigidaire ice maker problems?

    A:

    Some common problems with Frigidaire ice makers include clogged filters, malfunctioning ice mold thermostats and malfunctioning defrost systems that cause the condenser coils to frost. It is common for the ice-maker assembly to fail after long-term use.

    How long does it take to defrost a refrigerator?

    A:

    Depending on the size and method, defrosting a refrigerator or freezer can take anywhere from 10 minutes to a day. The most common method is to unplug the refrigerator or freezer, prop the door open and allow the ice to melt on its own. However, this method may take up to a day to defrost the appliance completely.

  • Q:

    Why does my refrigerator run all the time?

    A:

    Your refrigerator runs all the time due to a mechanical problem. This problem could be caused by a number of issues, ranging from dirty coils to a dying compressor. The fact that the refrigerator is running all the time indicates that it is probably not cooling properly. A normally functioning refrigerator should run only a few minutes at a time for adequate cooling.
