Excess refrigerant in a refrigerator can seriously affect its performance and cause problems such as high amperage, abnormal freezing, and damage to the suction line, including freezing. Knowing when there is excess refrigerant is crucial to preventing malfunctions and maintaining the appliance's efficiency. This article explains how to detect it, its symptoms, causes, and practical solutions so you can keep your refrigerator running properly and save energy.

The refrigerator is one of those appliances we use every day, but we often only clean it "when it starts to smell" or when a visible stain appears. The problem is that by the time you get to that point, there have already been spills, micro-residues, accumulated moisture, and, in some cases, cross-contamination between foods.

If your refrigerator has stopped cooling properly, it may have run out of refrigerant. This gas is essential for the cooling system to function and keep your food fresh. Recognizing this problem early can help you avoid further damage and preserve your food better. Knowing how to tell if your refrigerator has run out of refrigerant will allow you to act quickly and save on costly repairs.

When a refrigerator cools but doesn't freeze, it's usually a sign that something isn't working properly in its cooling system. This can affect food preservation, especially for foods that require sub-zero temperatures to stay fresh. Understanding why this problem occurs and which components to check can help you troubleshoot the issue and prevent food waste. Furthermore, keeping your refrigerator in optimal condition ensures that your food stays fresh longer.

The defrost heater is an essential component in modern refrigerators, especially frost-free models, as it prevents excessive ice buildup that can affect the appliance's performance. This heater warms the evaporator to melt the ice that forms, ensuring efficient and even cooling inside the refrigerator. Knowing the defrost heater's resistance (in ohms) is key to diagnosing whether it's functioning correctly and maintaining the refrigerator in optimal condition.

Detecting current in the refrigerator chassis is a clear sign of an electrical leak or grounding problem that requires immediate attention. This current can pose a risk of electric shock to anyone touching the appliance and indicates that the refrigerator is not functioning properly. Understanding why there is current in the refrigerator chassis helps prevent accidents, maintain home safety, and extend the appliance's lifespan.

It's common for many users to wonder why the lower part of their refrigerator isn't cooling. This can affect proper food preservation and lead to waste. Understanding the reasons behind this problem is key to taking corrective action and extending the appliance's lifespan.

When your refrigerator isn't cooling properly, it can directly impact food preservation and lead to waste. This problem can stem from various causes, such as a lack of refrigerant, which affects cooling capacity; a compressor that won't start, preventing the refrigeration cycle; or a frozen evaporator that blocks the flow of cold air. Understanding why your refrigerator isn't cooling is key to identifying the cause and applying an appropriate solution that will extend the appliance's lifespan and keep your food fresh.

In 2025, the technological world continues to advance by leaps and bounds, and one of the fundamental components of any device is the processor. Choosing the right processor can make a huge difference in overall performance, energy efficiency, and the ability to handle complex tasks. The three most popular processors in 2025 combine power and efficiency to meet the demands of users ranging from gamers to design professionals.

In the world of electricity, conductors play a fundamental role in the efficient and safe transmission of electrical energy. The types of electrical conductors vary according to their material, shape, and specific use, allowing them to adapt to different needs in residential, commercial, or industrial installations. Understanding the characteristics and advantages of each type allows for optimized performance and the prevention of common electrical problems.

Converting PDFs to Word is a common task, but it can be frustrating when the original formatting is lost or the document becomes disorganized. For those who need to edit or reuse PDF content, knowing how to convert it correctly ensures more efficient work and less time spent on corrections. Converting PDFs to Word correctly not only makes editing easier but also saves effort and improves productivity in personal or professional projects.

A frozen evaporator in a refrigerator is a common problem that affects its performance and efficiency. When the evaporator freezes, the circulation of cold air is obstructed, which can lead to poor cooling and increased energy consumption. Understanding why the refrigerator evaporator freezes allows you to take timely action, preventing further damage and extending the appliance's lifespan.
