What happened to the commercial refrigerator failure?

How to judge the inspection of the commercial refrigerator is a machine failure?

How do you self-assess before sending a commercial refrigerator and freezer for repair? Before you maintain the service, you can check the following points yourself: The following points are not machine failures, which is normal during operation.

1. The compressor is very hot: when the cabinet is running, the temperature of the compressor housing can be up to 90 degrees Celsius.

2, the heat of the condenser, the average temperature of the radiator of the radiator when the refrigerator is running is about 55 degrees Celsius.

3, the inside of the cabinet frost: because the cooling tube of the refrigerator near the rear of the refrigerator, the temperature is less than zero degrees Celsius when starting, when the refrigerator freezes again, it will automatically clear the frost.

4. When the freezer is in the automatic defrosting state, the temperature inside the box will increase slightly, and the cooling will resume after the defrosting.

If the freezer has the following reasons, we must carefully analyze it: if necessary, you should contact the manufacturer:

First, commercial refrigerators are not cooled

First check if the display shows the temperature. If not displayed, the machine is not turned on. Make sure the power outlet and plug are not loose. If there is no slack, check if the machine fuse is blown. If it is not two failures, you should contact the factory for sales at this time.

Second, secondly, the refrigeration effect of commercial refrigerators is not good.

If the displayed temperature is outside this range, first check the condenser for too much dust. If there is too much dust, clean the surface of the condenser. If you are looking at the freezer in the sun, keep it in a cool, airy place. Then check for debris that blocks the air inlet or air outlet. Remove debris.

Third, commercial refrigerator leakage

Regardless of whether the freezer is placed in a humid environment, the insulation of the electrical components will be reduced when the refrigerator is operated in a humid environment for a long time. Keep the refrigerator in a dry, well-ventilated place. If there is a significant electric shock, disconnect the power cord immediately. Then check if the power ground wire and fire line are in contact. If the problem still cannot be solved, please contact the factory for sales.

Fourth, the noise of the machine is very large.

First check for soft materials and noise caused by the winding of the blades. If this is the case, please clean it yourself to see if it can eliminate noise. If it is not such a voice, it is obviously a blow and shock. Please contact the factory for sales.
