These types are refrigerator columns, freezer columns, bottom freezer refrigerators, wine coolers and side-by-side refrigerators. If the evaporator fan is not working, the freezer or refrigerator will not cool adequately. The evaporator fan motor draws cold air over the evaporator coils and circulates it throughout the freezer. Single vs. Dual Compressors for Refrigerators. It is the evaporator that creates the cooling action of the refrigerator. In the refrigeration cycle, there are five basic components: fluid refrigerant; a compressor, which controls the flow of refrigerant; the condenser coils (on the outside of the fridge); the evaporator coils (on the inside of the fridge); and something called an expansion device. The freezer is surrounded by the evaporator tube. discoloration or deterioration of the refrigerator evaporator housing An evaporator fan draws air from the refrigerator and blows it over the evaporator coils. I've got a very nice split door refrigerator, bottom drawer freezer. These coils are very important in the cooling process because they allow the highly pressurized and heated refrigerants to get cooled.

The refrigerator has a low boiling point -20-degree celsius. In this low-pressure chamber, the ammonia expands, cooling rapidly as it does. There are many dual evaporator refri gerators available from brands like GE, LG, Samsung and others. The average consumer has not been able to afford this feature until the last decade when the dual evaporator concept was launched.

On most refrigerators, the coils are behind the bottom front grill. In single evaporator refrigerator -freezers, the evaporator temperature must be colder than the freezer. So the top evaporator coil totally froze up, including the … There are four parts (Expansion Valve, compressor, evaporator, condenser) and all are connected with copper or steel tubes. The refrigerant, which is now in a liquid state, passes through the expansion valve and turns into a cool gas due to the sudden drop in pressure.
Advantages of the Dual Evaporator There are a number of advantages to the dual evaporator cooling system. This unit has two separate evaporator coils, one for the refrigerator (fresh food) and another for the bottom freezer. Because its function is to absorb heat into the refrigeration system (from where you don't want it), the evaporator is placed in the area to be cooled.The refrigerant is let into and measured by a flow control device, and eventually released to the compressor. With dual evaporators, foods stay fresh longer because of the separate climates offered in the fresh food and freezer sections.

The refrigerator condenser coils can also be found at the top or at the bottom of the unit depending on the model. So the top evaporator coil totally froze up, including the drain.
These include keeping the freezer section at a constant temperature while the fridge is being used/filled, and ensuring that ambient temperatures can be preserved in one side of the fridge-freezer, even if the cooling … Fortunately, we have a little something that does all of these things for us – a refrigerator! There's something going on with these dual evap units, and Whirlpool is aware of it. I've got a very nice split door refrigerator, bottom drawer freezer. Brother PDuff brings this Whirlpool Service Pointer to our attention: Theres something going on with these dual evap units, and Whirlpool is aware of it. Your GE ENERGY STAR 23.8 cu. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. Made lots of ice in the wrong places. Refrigerator function: How does a refrigerator work? Refrigerator working principle. Per Service Pointer W10666205A dtd March 2014: Symptoms: Slow Ice/No Ice.
