The Basic Refrigeration Cycle

Shown above is a simple demonstration of the Refrigeration cycle. Look at the picture from the compressor going right. The compressor is a vapor pump. Hot vapor refrigerant leaves the compressor; it’s the hottest temp in the unit. That hot vapor travels to the condensing unit turning into hot refrigerant liquid. It then enters the filter dryer tube which cleans impurities the the system or any moisture or particles inside the seal system. Then the refrigerant goes to the metering device which controls the amount of refrigerant in the evaporator. There are many types of metering devices, they serve one purpose. They control the amount of refrigerant going into the evaporator. Cold liquid refrigerant enters the evaporator, and then it turns into cold vapor going into the Compressor. The cycle is repeated again and again.

 

Refrigerator Bi-Metal Thermostat

Displayed above is a bi-metal refrigerator thermostat. This component is mounted on top of the freezer evaporator inside of your refrigerator and is sensing the temperature in your freezer. When the refrigerator goes into defrost mode, the bi-metal must be good working condition, otherwise your refrigerator will not go into defrost mode. To check if this component is good, you should have no resistance at all if you measure resistance using your volt meter. When the bi-metal gets cold it closes inside and you should see resistance reading.

 

Refrigerator Overload Protector

Shown above is a refrigerator overload protector. It protects the refrigerator compressor from overheating. To check to see if it is good, the component must show resistance. This device is mounted on the compressor next to your current start relay.

 

Refrigerator Ice Maker with Control Module

Displayed above is a picture of a Refrigerator ice maker and a control module which controls all of the ice maker. If you are not making ice in your refrigerator then you have a bad ice maker control module or a bad refrigerator water valve. Note: check and clear any ice being stuck on the ice maker or check to see if your ice maker filling line tube is plug with ice.

 

Refrigerator Start Component

Picture above shows a Refrigerator Start component for a refrigerator. If your refrigerator is not cooling and you hear a clicking sound, then there is a high possibility that this part is bad. Kenmore , Whirlpool and some other refrigerators have this component.
