Daily maintenance method of low temperature refrigerator

Daily maintenance methods of low-temperature refrigerators 1.
Ensure the ambient temperature
.

The working environment temperature of the ultra-low temperature refrigerator should be below 30°C and the surrounding ventilation should be good
.

Excessive temperature or poor ventilation can easily cause the equipment to be overloaded and damaged
.

2.
Clean it once a month to ensure its cleanliness.
Use a dry cloth to remove a small amount of dust on the inside and outside of the refrigerator and accessories.
Be careful if the fan is installed
.

After cleaning, carry out a safety inspection to ensure that the refrigerator is plugged in properly, and do not connect it in a virtual way; to ensure that the plug is not too dirty in the refrigerator, use a neutral detergent, and then rinse it with pure water
.

But do not flush the inside and upper part of the refrigerator, otherwise it will damage the insulation and cause malfunction
.

Compressor and other mechanical parts do not require the use of lubricating oil
.

Unusually hot after cleaning the compressor; make sure the power and distribution wires on the back of the refrigerator are not cracked and nicked
.

3.
The cooling of the ultra-low temperature refrigerator is not sufficient.
Check whether there is frost on the surface of the evaporator; whether the refrigerator door is opened and closed frequently; whether the back of the refrigerator touches the wall; whether there are too many items
.

4.
Clean the cooling filter regularly (once every two months)
.

If the filter is not cleaned for a long time, the dust will block the mesh holes, resulting in poor heat dissipation, resulting in damage to the heat dissipation motor, and then damage to the compressor
.

Please refer to the instruction manual for cleaning methods
.

5.
If the noise of the ultra-low temperature refrigerator is too large, check whether the bottom plate is firm; whether the refrigerator is stable; if it is unstable, adjust the movable screws so that the four corners are firmly supported on the bottom plate; whether there is any object touching the back of the refrigerator
.

If the cooling effect is poor, the refrigerator does not stop, the radiator pipe is not hot, and the evaporator has a small airflow sound, these are due to the serious defect of the refrigerant caused by slow leakage
.

In the actual use process, there will be many other problems.
The solution to such problems requires continuous accumulation of experience to remove obstacles and make the ultra-low temperature refrigerator reach the working state
.

6.
Regularly clean the freezer door seal for freezing
.

If the door is not tightly sealed, the thermal insulation effect will be seriously reduced, which will easily cause damage to the compressor due to long-term overload operation
.

7.
The alarm is activated by the alarm When the alarm is activated by the alarm, it can usually be checked through the following aspects
.

First, check if there is a problem with the power supply or if the plug is pulled out of the socket; second, check if the internal thermometer is out of the proper range, in which case an item will heat up the refrigerator and set off an alarm; third, check Whether there are too many items placed at one time
.

The above is an introduction to the maintenance methods of low-temperature refrigerators.
I believe that everyone has a corresponding understanding of this after reading.
Doing a good job in the maintenance of the equipment can not only keep it in good working condition, but also prolong its service life appropriately.
Hope you all help
