The temperature in a refrigerator is kept low by a compressor that continuously circulates refrigerant gas through the system. As the refrigerant gas moves through the coils, it absorbs heat from inside the refrigerator, keeping the temperature low. This process is regulated by a thermostat that controls when the compressor turns on and off to maintain the desired temperature.
Change the gage from high to low.
BY evaporation of volatile liquid
It is because the air in the refrigerator's temperature is very low ,thus, the evaporation process is slowed down
To stabilize the temperature and make sure it doesn't get to low.
Your refrigerator may be too cold because the temperature setting is too low. To prevent food from freezing, you can adjust the temperature setting to a higher level. This can usually be done by turning the temperature control knob or using the digital display panel on your refrigerator.
There are a few different reasons why your temperature gauge always shows that the temperature is low. It may need to be fixed.
Because of the very low temperature inside a freezer, the sudden temperature change in the bulb when it switches on would make it pop.
It is put in a low temperature place(refrigerator?) therefore like water freezes and becomes solid.
The temperature of air in a refrigerator is about 3.3 Degrees Celsius
The thermostat senses the actual temperature in the fridge and compares it to the desired temperature (which the user sets on a dial), if the actual is above the desired it signals the compressor motor to run until the desired temperature is reached, when it stops the motor.
The recommended temperature for a refrigerator is 37 to 40 degrees Fahrenheit.
