How Does a Freezer Work?

A freezer is an amazing device that keeps foods such as meat and fish fresh for a long time. It is a vital unit in the kitchen. 

Therefore, it is crucial to know how it works, how to troubleshoot the problems, and the simple tips and tricks you can use to keep your freezer working effectively. 

One thing you need to understand is that a freezer makes the food cold by drawing the heat from them. It uses a simple process of taking away heat from the food to make them frozen. Components such as compressor, thermostat, coil, and others are involved in completing the process. 

Here is a step-by-step process of how freezers work:

  1. The moment you switch your freezer on, gas is inserted into the compressor where the compression takes place. The gas becomes hot, and it starts moving through the coils. 
  2. As it moves, it turns into liquid. The liquid then enters an expansion valve that has a small opening. The opening starts to blow out a very cold fog. 
  3. And as the fog passes through the coil, it evaporates and turns into a gas again. The fog temperature is around 27 °C. 
  4. Here, the fog takes heat from the freezer compartment. The cycle continues until there is no more heat. Hence, by drawing heat from the food, it gets frozen. 

Why a Freezer Can Be Too Cold

It is so surprising that a freezer can be too cold. This is because people own freezers to help them keep foodstuff cold but not too cold. Although you want your freezer to keep the food frozen, it can get spoiled when it is too cold. 

Below are some of the reasons why a freezer can be too cold:

The Temperature Sensor Might Not Be Working

This is an element that monitors the temperature of the freezer. It adjusts the damper, fans, and the compressor. Therefore, if it is not working correctly, it cannot adjust these components to keep the right temperature. 

In some cases, the temperature sensor just needs to be reset. By rotating the sensor, you can manage to reset it. However, you need to know where it is located to be able to perform the adjustment. 

To be certain, you can consult your freezer’s manual. This will make sure you adjust correctly. If the sensor does not work even after resetting, it might need to be replaced by an expert. 

The Settings Need to Be Adjusted

If you have noticed your freezer is too cold, you may need to adjust the temperature settings. But altering the temperature settings is not as easy as it seems. You need to use an accurate strategy to determine whether your freezer is too cold or not. 

One great way to check the temperature of your freezer is by using a freezer thermometer. Some freezers have an in-built thermometer while others don’t.

If your freezer does not have one, purchase a thermometer at the local store. In most cases, the freezer temperature should be at 0. Therefore, if it reads negative, adjust it to zero. 

The Air Damper Might Be Faulty

If your freezer is too cold, but the fresh section is normal, the main issue could be the air damper or freezer control. The air damper or the freezer control is an element of the freezer that controls the cold air. 

Thus, it is a very crucial part of your freezer. If it is faulty, the freezer might not be working as expected. It may fail to move the cold air to the freezer. And one sign that shows the air damper is defective is when the freezer is too cold. 

If the damper is faulty, there are a few things you can do. The first step is to switch off the fridge and remove the cover of the damper. This is to ensure nothing is blocking the damper. If everything is clear, the next step is to check whether the sensor is well attached. 

If everything looks good, but the freezer is still too cold, you may need to consult a professional.
