How to judge that the freezer has aged
Long-term use of the freezer will cause some large and small problems. The freezer in many people's stores has gradually become aging for some years. In this hot summer, if the commercial freezer in your store suddenly breaks down, is it particularly uncomfortable? The maintenance masters have been late, and repairs are very expensive after they come. Moreover, many black-hearted repairmen in the freezer industry have to replace many parts for some minor problems, and replacement parts can easily cause hidden dangers. Today, the editor of okmarts.com will teach you how to check whether the refrigerator is aging?
1. Check whether the freezer plug is normal
When the freezer was used for a few years, I suddenly found that the freezer was not cooling. The first thing we thought of was not that the power plug of the freezer was not plugged in, but how much money it would cost to fix it. However, when the maintenance personnel came, it was discovered that the power supply of the freezer was not plugged in properly. Therefore, when it is found that the freezer is not cooling, the power supply that needs to be checked first is loose.
2. Is the compressor running normally?
If the power supply is normal and the light in the freezer is also on, then please don’t worry, we need to find the compressor of the freezer now and listen to whether the compressor is working properly. It should be noted here that our body must not directly touch the compressor.
3. Whether the freezer buffer tube is broken
If the compressor of the freezer is operating normally, open the back cover of the freezer to see if the screw fixing the buffer tube is loose, because when the buffer tube is broken, the screw fixing it will become loose, we only need to replace a new buffer tube , And then tighten the screws.
4. Whether the refrigeration system is leaking
If none of the above occurs, you just need to plug in the freezer power supply for a few minutes and then unplug it, lie on the side of the freezer and listen for the sound of liquid flowing in the freezer refrigeration copper pipe. If you don’t hear it, then it is likely The freezer refrigerant leaked. If there is a refrigerant leakage, you need to find professional maintenance personnel to repair and add refrigerant.
5. Whether the freezer door seal is aging
If everything is normal but the freezer is still not cooling, you can check whether the freezer door seal is aging or deformed. We can ask the professional maintenance personnel of the freezer to change the seal.
