Detailed list of common problems in cold storage and troubleshooting!

Cold storage is a very common piece of equipment. It is generally used to store products that must be kept fresh, or to extend the service life of the product. Therefore, once it is damaged, it will cause damage to the internal products, and repairs are urgent. If you want to get a quick and effective troubleshooting solution, you have to find Hong Kong Junhong Electrical Repair. The recent maintenance case of Bingcan Ice Storage illustrates this point. Hong Kong Junhong Electrical Maintenance teaches you how to understand fault problems.

1. Unable to start cold storage

1. Power failure. Generally, if the power supply trips, it may result in failure to start. Trips may generally be caused by short circuits, open circuits, poor wire contact, etc. Therefore, maintenance personnel need to directly check and replace the faulty parts to ensure that the wires are in good contact.

2. Abnormal current. If you use a multimeter and find that the current is too large, this can easily cause damage to the motor and may also cause the equipment to overheat. Therefore, it is necessary to check and tighten the terminals, clean the condenser, and check whether the heat dissipation is normal.

2. Start the cold storage and find that the pressure gauge is abnormal.

1. The low pressure is too low. If the low pressure is too low, the pressure gauge will be damaged and often fail to function properly. You can check whether it is caused by insufficient refrigerant or leakage in the system pipeline. Troubleshoot and repair the corresponding problems.

2. The high pressure is too high. Be sure to clean the condenser fins in time to improve heat dissipation and reduce the ambient temperature. Because high voltage is usually caused by poor heat dissipation. It may directly cause damage to the accessories of the cold storage for a long time.

3. Start the cold storage, but the temperature does not drop.

1. Check the amount of refrigerant. A small amount may affect the temperature condition, while a large amount may cause frosting on the pipes, ultimately affecting the temperature. Therefore, it is necessary to check and adjust the amount of refrigerant, clean or replace the oil return pipe, and repair or replace the oil separator.

2. Fan problem. The fan may be deformed due to the ambient temperature, or there may be a lot of stains, causing speed problems, which will also affect the temperature adjustment. Therefore, the maintenance master needs to directly check and replace the deformed fan blades and clean the fan blades.

To sum up, we can see that many faults can actually reduce the risk through routine maintenance. After the repairs are completed, the masters of Hong Kong Junhong Electrical Appliance Repair will also give users more daily maintenance tips to help users understand how to use the equipment normally, which can greatly reduce the cost of repairing cold storage.
