How do freezers and fridges work?
A fridge freezer, like a pressure cooker, changes the pressure in a sealed unit to alters the boiling point of the liquid.
Your fridge and freezer work by continually compressing a refrigerant in a liquid into a gas, and then condensing that gas back into a liquid.
- Next, the refrigerant starts in your fridge/freezer as hot gas and is pushed from the compressor through a series of condenser coils where it is cooled and returned into a liquid.
- Next, that liquid is then pumped through a capillary tube which removes any moisture or contaminants before being sent to your fridge/freezer's evaporator coils.
- Then, your fridge/freezer’s evaporator coils expand and turn from a liquid into a gas, thus it draws heat away from the system and makes the items in your fridge cold.
- Finally, the gas is then returned to your compressor where the whole process starts again.
So you knew easy how to do freezers and fridge work.
4 Reason make your Fridge not cooling and freezing
Sometimes nothing gets broken about your fridge, despite the fact that it doesn't freeze and cool. There are several reasons that you can take to save yourself from any unnecessary service fees.
Reason 1: Your refrigerator is not plugged in.
Lots of people quickly come to conclusions without checking whether or not power is being fed into their fridge. Don’t be one of those, we need to check the power supply and plug in it.
Reason 2: The thermostat has been turned down.
We need to locate your thermostat and check that if it is set at the appropriate temperature. The side-by-side freezer/refrigerator thermostat is usually located at the back.
Reason 3: The door of the fridge is not closing properly.
Double-check the gaskets and doors after closing. Notice the light in the fridge, whether it turns on and off when the doors are closed? if not, the door might not be functioning properly.
Reason 4: The cold air can not circulate.
The airflow can be blocked from circulating through your fridge due to your boxes of food, which prevents your refrigerator from cooling. So you need to arrange and clear out some of the food suitably.
Ensure Fridges and Freezers are running efficiently
- Set the temperature to the appropriate level: Check-in your fridge or freezer, be careful not to under or overcook the items. Over cooling will cause the fridge/freezer to work harder than it should and undercooling will cause food to spoil quicker than it should. Remember your fridge should be set between 36-42 degrees Fahrenheit, and the freezer 4-5 degrees Fahrenheit.
- Make sure your fridge and freezer are at least 2 to 3rd full: The items in your fridge/freezer will act like thermal batteries and actually help to reduce the fridge/freezer’s workload.
- Clean your fridge’s condenser coils: Day by day, the lint, dust, and debris from your kitchen can build up on the fridge’s condenser coils. Let get a stiff (with non-metallic bristles…nylon for instance) brush to clean/remove the debris, this will help your system run more efficiently.
