Refrigerators are the treasure of many businesses in summer, especially in the catering industry. Refrigerators are the top priority in summer. However, faults can also occur in top-tier appliances. The masters of Hong Kong Junhong Electrical Appliance Repair have encountered many problems related to the fault warranty of refrigerators. Today, follow his master to repair the Penguin refrigerator, so that the faults and maintenance problems can be clearly understood!

1. The refrigerator is not refrigerated enough.

Refrigerator refrigeration problem is one of the issues that users are most concerned about. Generally, there are several reasons for insufficient cooling.

1. The refrigeration system is faulty. Usually the compressor is not working, the refrigerant is leaking or insufficient, or the evaporator is frozen, etc. The maintenance technician's solution is often to first check whether the compressor is operating normally. You can check the voltage and current with a multimeter. If there is no problem with the compressor, it means that the refrigerant is insufficient or leaking, and you only need to find and repair it accordingly.

2. Thermostat failure. An imbalance or damage to the thermostat may cause cooling problems, which requires the master to disassemble the thermostat for inspection, repair and replacement. Generally speaking, replacement is a relatively cost-effective method.

3. Poor heat dissipation. Although it is a refrigerator, heat dissipation promotes air convection to cool down the interior. Therefore, if the radiator on the back or bottom of the refrigerator is dirty, it will affect the heat dissipation effect, so it is necessary to clean the radiator regularly.

2. Refrigerators are noisy

1. Compressor noise. If you use an older refrigerator, the compressor may have aged or the internal parts may have become loose, which will naturally cause noise. Aged compressor parts can be replaced or friction can be relieved with lubricating oil.

2. Fan noise. If the fan is dirty or touches some foreign objects, it may produce noise. Just need to clean it up.

3. The placement is not stable. Generally speaking, if there is noise in a new refrigerator, the placement has a lot to do with it, so you can properly check the ground and surroundings and adjust the position.

3. The refrigerator door is not tightly sealed.

The door of the refrigerator has a sealing strip, so if the strip is dirty or damaged, it may affect the sealing performance. You only need to clean the sealing strip or replace the damaged sealing strip to increase the sealing performance.
