When the household refrigerator has stopped freezing, you need to understand the cause of such a failure as soon as possible. Immediately the problem can not be noticed, because the motor-compressor is working absolutely perfectly. But soon you will start to get spoiled products, so the equipment must be saved.
In the article, we will analyze the main root causes of a refrigerator malfunction, which lead to poor cooling in the chambers.
The refrigerator works, but does not freeze: what to do
Users who have recently purchased new equipment often ask the question: “Why is my new refrigerator suddenly not freezing?” The reason is the transportation of equipment to a new place. It should take at least 1-2 days until the motor starts to properly pump cold to cool the food.
If you just loaded the shelves with products, the motor can work for an hour or more without pauses while cold air is being pumped.
Some are faced with this problem: the refrigerator freezes slightly, while the compressor is hot. What causes this failure? Most often, the cause is a malfunction of thermal protection, which protects the motor from overheating. Before repairing the equipment, follow these simple steps:
- disconnect it;
- remove all food and defrost.
If after defrosting the compressor works, but heats up, it is better to turn off the refrigerator and call the repairman.
Does the two-chamber refrigerator buzz and gurgle at work? These are normal phenomena if the noise level does not exceed the established norm.
The upper chamber does not freeze: reasons and self-repair
Why does the freezer perfectly freeze, but is the rest of the refrigerator warm? There can be many reasons. Consider simple problems that you can fix yourself:
- Check that the door is snug against the body. Perhaps the compartment is crowded and something is stopping normal closure. It happens that the rubber seal is worn out or dirty. Replace easily with your own hands.
- Check the set temperature. When the room is hot and poor ventilation, and in the compartment the thermostat is set to full power, the engine will not be able to cope with the load. If the equipment is with one motor, the cold will pass into the lower chamber, which will freeze very much. And in the upper compartment it will be warm.
- Is the fan spinning? If its blades are overgrown with ice and do not rotate, then it is not surprising that cold air does not enter the compartment. Defrost the refrigerator or replace the fan motor.
But if your actions did not lead to the desired result, then there has been a serious breakdown. We will give examples of problems, but in some cases you can’t do without the help of a wizard.
- The engine of the refrigerator works, but does not freeze. At the same time, the light in the compartment is on. This happens when the compressor wears out: it does not have enough power to pressurize the cooling pipe.In twin-engine refrigerators, the option is possible when the engine of the refrigerator compartment burns out, and the engine of the freezer continues to work. You may notice oil leaks at the bottom of the housing. The compressor is being replaced or repaired.
- Refrigerant outlet in the closed part of the refrigerator. One of the walls is bloated, ice and snow are growing inside the chamber. The master opens the sealed part, finds the place of breakage and eliminates the leak. Then it refills the system with freon. Sometimes a replacement evaporator is required.
- Gas leak through microcracks in a steel casing. As a result of clogging of the drainage system, moisture drops fall on the circuit, which leads to corrosion. The refrigerant starts to leak. Trimming and soldering of the damaged part is carried out, freon filling.
- Gas outlet due to chamber depressurization. The chamber wall is damaged or punctured. You can fix the problem by repairing a puncture and restoring the tightness.
- Faulty start relay. That relay allows you to turn on and off the engine. Parts are being replaced.
- The problem with the temperature controller. When it breaks, the module cannot "understand" what temperature is in the compartment. Therefore, the motor does not start or runs without stopping.
- Blockage of capillary tube or dehumidifier filter. Because of the obstacle, Freon does not pass through the entire cooling system, as a result, one of the chambers does not freeze. The system is being cleaned and refrigerant charged.
As you can see, there are many possible problems - you can’t figure it out on your own. Accurately determine the location of the breakdown will help the diagnosis of technology.Such malfunctions occur as a result of improper use of the refrigerator or wear of parts. Therefore, follow the instructions, conduct periodic maintenance to maintain the normal operation of the refrigerator.
