1. Tips to Fix a Fridge Not Cooling, Preventing Food Spoilage, and Extending Appliance Lifespan
A fridge failing to provide sufficient cooling not only leads to food spoilage but also skyrockets electricity bills. So what are the effective troubleshooting tips without needing a repair technician?
According to technology experts, the issue of a non-cooling fridge is prevalent in many households. There are various causes, but timely intervention is crucial to prevent adverse effects on stored food and the fridge's lifespan. Therefore, upon noticing this issue, users should inspect to identify the root cause because, in some cases, simple causes can be rectified without requiring a technician.
There are various reasons why a fridge fails to cool, and knowing them can help effectively troubleshoot. Illustrative image.
Fridge Door Not Sealing Properly, Rubber Seal Damaged
Many people have a habit of frequently opening the fridge but neglect to ensure proper closure, resulting in the door not sealing tightly. There are also cases where the rubber seal is damaged or torn, preventing the door from closing properly... all of these can easily allow cold air to escape, leading to the fridge not cooling. If the cause is from the user, paying more attention to fridge usage is necessary; if it's due to a damaged rubber seal, consider purchasing a higher-quality replacement.
Temperature Control Button Misaligned
In many cases, a fridge not cooling is due to the fridge being set at a low cooling level or in energy-saving mode. When noticing the fridge not cooling, check if it's set at a low cooling level or in energy-saving mode.
Light Switch Inside Fridge Not Working
The light switch helps identify whether the fridge is operational. If the fridge door is opened but the light doesn't turn on, inspect the plug, connectors, and if no issues are found, it indicates an internal malfunction. For safety reasons related to electrical systems, it's advisable to call a technician to rectify the issue.
Excessive or Insufficient Food Inside the Fridge
Many people tend to overcrowd the fridge, leaving insufficient space for air circulation, thus hindering proper cooling of the food. Conversely, having too little food inside can also affect the fridge's performance negatively. Therefore, it's best to maintain an adequate amount of food while the fridge is running.
Defective Ice Dispenser
Not many are aware that a malfunctioning ice dispenser can cause frost buildup around the evaporator coils, impairing the cooling function of the fridge. Therefore, regular cleaning of the fridge is essential for optimal performance and durability.
Inappropriate Temperature Settings
Fridges typically have two compartments: a freezer with a negative temperature and a refrigerator with a positive temperature. During winter, setting the temperature at level 1 achieves -18°C in the freezer and 2–5°C in the refrigerator, while the vegetable compartment reaches 7–10°C. However, in summer, to maintain these temperatures, it's necessary to adjust to level 4 or 5 due to external temperature changes. Additionally, temperature adjustment depends on the amount of food stored inside. If there's a lot of food, set the temperature higher to provide more cooling, preventing food spoilage.
Moisture Blockage
When a fridge experiences moisture blockage, a clear sign is frost forming on the evaporator coils, followed by melting, hot and cold cycles, or short operational cycles. If this is observed frequently, it's likely due to moisture blockage. In such cases, calling a technician is necessary to evacuate the gas, remove moisture, replace the dryer, vacuum, and recharge the gas.
Fridge Gas Shortage
When a fridge fails to cool, immediate consideration should be given to gas shortage. If the fridge lacks or leaks gas, it exhibits symptoms such as poor cooling, despite the compressor operating normally, leading to compressor damage and affecting food quality. If gas shortage is suspected, check for leaks by applying soapy water to the pipes, condenser, and evaporator. If bubbles appear, indicating a leak (usually found at the evaporator). Users can also use a matchstick to detect gas shortage (Note: do not use a lighter). While the fridge is running, light the matchstick and heat it near the end of the condenser. If the pipe segment heated by the matchstick cannot be touched due to excessive heat, it confirms gas shortage. If the fridge has sufficient gas, the gas will evaporate, cooling the pipe segment, allowing users to touch it without discomfort. When gas shortage occurs, the only solution is to call a technician for refilling, avoiding self-refilling to prevent safety hazards.
