Common after-sales issues and solutions for commercial refrigerators

Commercial refrigerators are essential equipment for hotels, supermarkets, restaurants, and other places. They are used to store food and beverages and keep them fresh. Commercial refrigerators are frequently used and with intense working, so they are facing various after-sales issues. The following are some common after-sales issues and solutions for commercial refrigerators:

  1. Poor refrigeration effect


Compressor fault: The compressor is the core component of commercial refrigerators, responsible for compressing the refrigerant, making it absorb heat and evaporate in the evaporator, thereby reducing the temperature in the refrigerator. If the compressor malfunctions, the refrigeration effect will decrease.

Refrigerant leakage: The refrigerator is not well sealed, resulting in leakage of cold air, which will also cause poor refrigeration effect.

Capillary blockage: The capillary is the channel for the circulation of refrigerant. If it is blocked, the refrigerant cannot flow smoothly.

Air duct blockage: The fan is a component that blows cold air to every corner of the refrigerator. If the air duct is blocked, the cold air will not circulate smoothly.


Replace the compressor

Repair the leakage

Clean the capillary

Clean the air duct

  1. Loud noise


Compressor working noise: It is normal for the compressor to make noise when working. But if the noise is too loud, it may be that the compressor is faulty or improperly installed.

Fan noise: The fan will also make noise when it is working. If the fan bearing is worn or the fan blade is deformed, the noise will increase.

Pipe vibration noise: The refrigeration pipeline is not installed firmly, and it will vibrate when the refrigerator is running, causing noise.


Repair or replace the compressor

Replace the fan

Tighten the refrigeration pipeline

  1. Frosting


Frequent opening and closing of the refrigerator door: It will cause warm air to enter the refrigerator and condense and frost.

Excessive humidity in the refrigerator: The evaporation of moisture in the food will cause the humidity in the refrigerator to increase, and the water vapor will condense into frost when it is cold.

Drain pipe blockage: The blockage of the refrigerator drain pipe will cause the condensed water to be unable to be discharged, and accumulate in the refrigerator to form frost.


Reduce the frequency of door openings

Clean the refrigerator regularly to remove moisture from the food

Clean the drain pipe

  1. Electrical appliance failure


Power supply problem: Unstable power supply voltage or poor grounding will cause electrical appliance failure.

Motherboard failure: The motherboard is the control center of the refrigerator. If the motherboard fails, the appliance will not work properly.

Display screen failure: The display screen is responsible for displaying the temperature, working status, and other information about the refrigerator. If the display screen fails, the relevant information cannot be read.


Check whether the power supply is normal

Replace the motherboard

Replace the display screen
