 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
