When it comes to troubleshooting problems with your fridge’s temperature controls, it’s essential to have a basic understanding of how they work. Refrigerators use a thermostat to regulate the temperature and keep your food fresh.

The temperature controls can vary depending on the make and model of your fridge. Some fridges have a basic control system with a dial that adjusts the temperature, while others have more advanced digital controls that allow for precise temperature settings.

Tip: Check the user manual to see what type of temperature controls your fridge has and how to operate them correctly.

The Different Types of Fridge Temperature Controls

There are two main types of fridge temperature controls:

  1. Mechanical Thermostat: This type of temperature control uses a manual dial that adjusts the temperature by opening or closing the damper. The damper controls the amount of cold air that enters the fridge from the freezer compartment.
  2. Electronic Control: This type of temperature control uses a digital display to set and maintain the fridge’s temperature. It can be more precise than a mechanical thermostat and may have additional features such as a temperature alarm or vacation mode.

How Fridge Temperature Controls Regulate Cooling

The temperature controls in your fridge work by regulating the flow of coolant through the evaporator coils. The compressor compresses the coolant, raising its temperature, and then pumps it into the condenser coils, where it cools off. The coolant then moves through the evaporator coils, where it absorbs heat from the fridge’s interior, lowering the temperature. The temperature controls regulate the amount of coolant that flows through the evaporator coils and how much cold air is circulated in the fridge.

Tip: If you notice that your fridge is not cooling properly, the first step is to check the temperature controls and ensure they are set correctly. If the temperature controls are functioning correctly, then you may need to troubleshoot other potential issues, such as a blocked air vent or dirty condenser coils.
