Home Appliances Tips: Causes and Solutions to Refrigerator Freezing

I believe that many people have such distress, after a period of time in the refrigerator, a thin layer of frost will develop on the walls of the refrigerator, which will become thicker and thicker if not treated in time. The capacity of the refrigerator will therefore shrink, and it looks quite unsightly, so what causes the refrigerator freezer to freeze? There are many reasons why the editor has summarized the following points for everyone:

First, the temperature of the refrigerator compartment is too low. The temperature of the refrigerator compartment should be set between 4-8 degrees. If the thermostat is mechanical, the gear should be properly adjusted according to the seasonal temperature. In summer, the gear should be adjusted to 1-2. In spring and autumn, it should be adjusted to the third gear. In winter, it should be adjusted to the 4-5 gear. The freezer temperature is about minus 18 degrees, and the freezer temperature is between 0-10 degrees, preferably between 4-8 degrees.

Second, the door seal seal is not strict or frequent opening or opening time is too long lead to serious loss of cold air inside the cold room. If seals are not tightly sealed, new seals should be repaired or replaced in time, and the number of open doors or time should be minimized.

Third, the refrigerating chamber rear wall deformation convex now refrigerator freezer evaporator is built-in type, if the refrigerator compartment rear wall deformation convex, it will lead to separation with the evaporator inside to form a gap, this will certainly Affects temperature conduction, resulting in longer compressor operating time and increased power consumption.

Fourth, the thermostat itself has a fault that causes the compressor to stop working for a long time. If it is a mechanical thermostat, there are three reasons:

1. There is a loose movement of the temperature sensor's temperature sensor. The loose temperature sensor should be restored to its original position and fixed so that it can be in close contact with the evaporator in the refrigerator's back wall.

2. The internal contacts of the thermostat have been conglutinated. The emergency treatment method is: first cut off the refrigerator power, rotate the thermostat knob to 0-speed, and then rotate to the highest level, so that repeatedly rotating a few times, generally can make The contact is separated and the gear is set to 1-2. After 5 minutes of power failure, the power supply is switched on again. If the compressor can be stopped, the fault is cleared.

3, thermostat heat pipe damage leakage failure, should replace the new thermostat, the general electronic market refrigeration component stores 25 yuan a.

So how to reduce the phenomenon of refrigerator frosting in daily use? I suggest you should pay attention to the use of:

First, try to reduce the number of refrigerator door opening and opening time;

Second, the refrigerator door must be closed strictly to prevent air leakage;

Third, the freezer to place food to leave a certain gap, try not to close to the back wall of the refrigerator chamber, place a large amount of food moisture is best to use plastic wrap to seal;

Fourth, pay attention to whether the drain is blocked by dirty things. If it is blocked, clear it in time.

5. In addition, the user of the refrigerator should also pay attention to timely adjust the thermostat gear position or temperature setting according to the temperature change, generally winter transferred to 5-7 file (temperature 2-4 °C), summer is 1-3 files (temperature 6-8 °C ). There is a problem that there is no frost in the freezer. It may be because the temperature is too high.
