First, why should there be a separate circuit in the freezer?
Because the same outlet or power supply is used with other appliances, the power supply voltage becomes unstable, and the appliances often begin to cause voltage drops. In particular, when the power reaches the peak, the voltage is too low and the compressor will not start, or in severe cases, the compressor will not stop automatically. In addition, the compressor may be damaged.
Second, the cold air in the freezer is always leaking.
後 After long-term use, the aging and deformation of the door self-sealing strip will cause cold air to leak from the cabinet, reducing its cooling effect.
The inspection method is to first open the flashlight in the cold interior, close the door, and then carefully observe whether there is a gap between the freezer and light leakage, and clean the seal with washing powder. The seal will open and stick. Seal a piece of sealing tape on the original, and then check that it still does not leak. Repeat the test for this patch until the light does not leak.
Third, why can't the freezer start?
1. Whether the power supply voltage is within the specifications. Generally, the voltage should not exceed the range of 187 to 242 V. If it is not within this range, it should be installed by a voltage regulator or a professional electrician.
2. Poor contact between power supply and freezing plug;
3. The ambient temperature of the freezer should not be lower than 5 steps. Otherwise the compressor will not start.
4. The low temperature compensation switch is not turned on, the low temperature compensation switch is faulty, and the low temperature compensation heating wire cannot be turned on.
5. When the temperature controller reaches the zero position, the thermostat will fail.

If the freezer wants to use it for a longer life, beyond its own quality standards, it also needs to be properly maintained and maintained. First of all, it must make the freezer a good environment for use.
First, there should be no unevenness between the freezer and the ground during installation, and it should be kept level and stable, otherwise it will affect the drainage. Poor drainage will affect normal refrigeration and damage the fan.
2. The freezer should not be close to the heat source and not be exposed to direct sunlight. The freezer should also ensure that the natural wind flow speed should be less than 0.2 m / s. The surrounding channels and air vents should be closed to prevent damage to the temperature in the freezer and affect the cooling effect.
3. During the use of the freezer, the voltage change should be kept within the range. If the voltage is not stable, please choose a suitable, safe and reliable voltage regulator.
4. The freezer should be used in a good environment. Generally, the room temperature is lower than 25 degrees and the relative humidity is lower than 60%. Under the conditions of higher temperature and humidity, the freezer operation will be affected to some extent.
5. During the automatic defrost process of the freezer, the temperature in the freezer will rise for a short time, which is normal.

First, frequent power outages will cause some damage to the freezer at the next startup.
1. Frequent power failures are very harmful to the freezer. When the freezer is suddenly closed during normal operation, it takes at least 5 minutes to turn on, which will affect the life of the compressor.
2. The freezer is not a problem when it is not working, but if the compressor is suddenly turned off and immediately powered on, the thermal protection is stopped because the freezer does not work because the pressure difference between the two ends of the compressor is very large. If the cryo-protected area is damaged, the engine may be burned.
Secondly, long-term parking of refrigerators should pay attention to these tasks.
1. If the energy has not been energized for a long time, the refrigerant will change from a gaseous state to a liquid state during operation, which will cause pipeline damage and cause leakage. The effect will be very bad on the next cool down.
2. Allow the freezer to extend its service life better. It is important not to let the commercial freezer shut off frequently.
3. When using the refrigerator again, perform the corresponding inspection and cleaning work.
If the freezer is re-enabled after a long period of time, what are the dangers, what should I watch out for and how to fix and resolve the problem?
Dangerous after long periods of inactivity.
1. The long-term deactivation of the refrigerator will cause the lubricant in the compressor to sink to the bottom, and all the workpieces in the machine will dry. At this point, if it is turned on, the compressor piston will run without lubrication, which will affect the life of the compressor. This will cause economic losses.
2.How to start a long-term decommissioned freezer
When restarting the freezer or refrigerator after a long period of inactivity, three instant startups are required. The specific method is: connect the power and then disconnect, repeat every 5 minutes, turn on and off 3 times in total.
3.Recommendations for freezer
If you find abnormal noise or shutdown after initial startup, if you cannot recover from refrigeration or leakage, you should ask a regular company professional for repair. Do not disassemble and repair by yourself, so as not to expand the fault scope.

Freezer condensation causes:
Supermarket freezer can extend the low temperature shelf life of the product. In order to prevent cold air from leaking and keep the cabinet at a low temperature, the heat insulation layer on the door seal will cause the cold air to escape and maintain the cooling effect in the cabinet. The temperature inside the cabinet is low, the temperature is high in summer, and the temperature difference between the inside and outside of the cabinet is large. When the temperature around the cabinet reaches a certain level, the door seal will have a condensation effect. If there is water droplets in the cabinet, there will be small water droplets. The lower the temperature, the more water drops.
First, why does condensation occur?
部 The interior of the freezer should always be kept at a very low temperature, especially in the freezer; the temperature is generally less than -18 ° C. Although the freezer door seal has sufficient thermal insulation capacity, it cannot be compared with the door and cabinet. However, the temperature around the freezer in summer is very high, and the temperature difference between inside and outside increases significantly. Once the humidity around the freezer reaches a certain level, the door seal will reach the "condensing point" and the bottom door of the freezer will be clearly sealed. This is because the bottom of the freezer has the lowest temperature, so condensation may appear on the bottom of the freezer door seal.
Secondly, how to solve this situation when the condensation occurs?
The appearance of dew condensation is very normal, because air vapor encounters air dew below 0 degrees. Dry with a clean towel. Placing the cabinet in a ventilated place helps to dissipate heat, improve the cooling effect, shorten the working time of the compressor, and reduce the occurrence of water drops.
How to reduce condensation?
The first thing I told consumers was that they didn't have to worry about the summer door condensation. This is normal. In order to reduce the occurrence of condensation, please pay attention to the following points when using:
1. The temperature adjustment gear should be adjusted in the low speed gear as much as possible, such as 1-3 gear;
2. In the summer rainy season, the surfaces of the freezer door and other components are often gently wiped with a soft cloth to reduce the phenomenon of condensation;
3. Place the freezer in a well-ventilated place.
