Why Your Fridge is Freezing Up at the Back and How to Fix It

Introduction to Fridge Freezing Issues

A fridge that is freezing up at the back can be a frustrating and annoying problem. It not only affects the quality of food but also leads to higher energy bills.

A refrigerator is an essential appliance in every home, and it is designed to keep our drinks, fruits, veggies, and perishable foods fresh for a longer time. However, when it starts freezing up at the back, it becomes a nuisance that needs immediate attention.

Understanding Your Refrigerator’s Functioning: Before delving into common causes of fridge freezing up at the back, it’s essential to understand how your refrigerator works.

The refrigerator operates by maintaining a balance between cooling and defrosting cycles. The fridge function depends on several components such as refrigerant gases, compressor, evaporator fan motor, thermostat and sensors.

The refrigerant gases flow through tubes from the compressor and evaporator coils located in different parts of the fridge; this creates an alteration in temperature creating cool air which flows through air ducts into the fridge compartment via a damper or air door which regulates airflow. Additionally, there are defrosting mechanisms integrated into refrigerators that ensure any ice build-up doesn’t form on critical components like evaporators or fans while still allowing for optimal functioning of other integral parts like compressors or thermostats.

Understanding Your Refrigerator’s Functioning

A refrigerator is an essential appliance in any household, and it is often taken for granted until it starts malfunctioning.

A fridge serves the purpose of keeping your food and drinks cool by removing heat from its interior, but how does it work? To understand how a refrigerator functions, you need to know its various parts and their roles.

The main components of a refrigerator are the compressor, condenser coil, evaporator coil, expansion valve or capillary tube, and refrigerant gas. The compressor plays an integral role in the functioning of a fridge by compressing the refrigerant gas into a high-pressure state before sending it to the condenser coil to release heat.

The refrigerant gas then moves through the expansion valve or capillary tube, where it expands and cools before moving to the evaporator coil. The evaporator coil absorbs heat from inside the fridge while cooling down its contents.

This process removes heat from inside your fridge and keeps your food fresh for longer periods. Now that you have a basic understanding of how a refrigerator works let’s discuss some common problems that can occur with this appliance.

Issues such as faulty thermostats or temperature controls can often cause fridge freezing problems where frost builds up at the back of your freezer compartment. This can result in warm air escaping from your fridge due to blocked vents leading to higher energy consumption and spoilt food items.

Other issues such as door seal issues or overstuffing the fridge can also affect its functioning leading to unnecessary ice build-up at the back which will further escalate these problems if not addressed timely. However, there are simple preventive measures that you can take for regular maintenance which we will be discussing later in this article

Common Causes of Fridge Freezing Up at the Back

Firstly, check for any visible damage or wear and tear on the seal. Look for cracks, tears or missing pieces.

If you notice any of these issues, it’s likely that your door seal needs replacing. Another way to test if your door seal is functioning properly is by performing a dollar bill test.

Simply place a dollar bill between the seal and fridge frame and close the door. If you can easily pull out the bill without feeling any resistance, then your seal isn’t creating an airtight environment and needs replacing.

Overstuffing the Fridge

If your fridge is freezing up frequently, it might be due to overstuffing.

When you put too many items in your fridge, there will not be enough space for air circulation, leading to poor airflow and inadequate cooling of your fridge. Overstuffing can also cause contact between containers and produce with the cold air vents, which obstructs airflow and increases the likelihood of frosting.

To prevent this from happening, make sure you don’t pack your fridge too tightly. Leave sufficient space between items to allow for proper ventilation in the appliance.

Be mindful of where you place things inside the refrigerator so that they don’t block airflow and keep an eye out for food that may have fallen onto vents or shelves as it can restrict cool air circulation. Another thing to consider is how often you access your fridge.

Frequent opening and closing of the door can release moisture into the freezer section, creating frost buildup on any exposed surfaces inside – including food products – which can lead to problems with defrosting later on down the line. Therefore, it is best practice only to open the door when necessary and close it promptly after use so that cold air does not escape from within quickly.

Blocked Vents

Another common cause of fridge freezing up at the back is blocked vents.

The fridge evaporator fan located in the freezer circulates cold air into the refrigerator through a vent. If that vent is blocked by food or other items, it can cause the air to build up in the freezer and create frost on the back wall.

This can also lead to uneven cooling in different parts of the fridge and even spoilage of food items. To fix this issue, you will need to open up your fridge and locate the vents that are usually found at the back of its interior walls.

Check for any obstructions such as food items or debris that may be blocking these vents. Remove any unwanted objects and ensure that there is proper airflow through all vents.

Proper airflow ensures optimal functioning for your fridge’s cooling system, which can prevent future issues with excess frost buildup. In addition to clearing out any blockages, it’s important to keep an eye on your refrigerator maintenance routine as well.
