Causes and methods of repairing freezer ice maker failures

No matter what season, ice making is indispensable, and summer is the "peak season" for ice making machines. This is why most ice making machines have various problems. For example, if the ice making machine in the freezer appears, Question, how to repair it?

1. Common freezer problems

1. Not cooling: If the freezer is not cooling, first check whether the refrigerant liquid is leaking or the two-way solenoid valve is damaged and is not closed tightly.

How to solve: As for the solution, check for leaks and then repair them and add refrigerant or replace the solenoid valve.

2. Ice making is abnormal; for example, it can work regularly during the ice making process and pump water normally. The key reason for the problem is that it cannot automatically enter the ice removal program and drop ice.

Solution: The main reason at this time is that the probe for measuring water temperature is malfunctioning. Because it has no perception, it loses its working ability, causing the program to appear. During maintenance, first measure the resistance of the water temperature probe with a multimeter. Through the test, you can see that the water temperature in the water tank is close to 0°C. At this time, you need to unplug the three-core wire in the control box and test the resistance of the two wires on both sides. . When the resistance value is above 27K, it can basically be determined that the controller is faulty and needs to be replaced in time. If it is lower than this value, you need to disconnect one of the two wires and adjust the resistance value to between 27K and 28K by connecting the resistor in series. That’s it.

2. Precautions for maintenance of freezer ice machine

1. Make preparations; adequate preparations will help the maintenance work go smoothly, while ensuring that the program is not messy and the finishing work will be particularly convenient.

2. Safety matters; the first factor is to cut off the power. No matter what kind of home appliance is repaired, the first step is to cut off the power. This is especially true for ice machines. Whether it is replacing parts or checking the cause of the fault, the power should be cut off first. Go to the next step.

3. Testing and debugging after maintenance: After the ice machine is repaired, the work is not completed. There is another key step, which is testing. Only through testing can we know whether the repair was successful and whether the relevant functions have returned to normal working conditions. Only through testing can the integrity of the entire process be ensured. Therefore, testing at the end of maintenance is necessary for both users and maintenance personnel.

4. Carry out follow-up work; for maintenance staff, follow-up investigations must be conducted after two days of maintenance or a few specific working days.

From the above sharing, we can know that the maintenance of the ice machine is not a simple operation process, but requires professional and skilled maintenance. Therefore, if an individual does not have the professional knowledge and equipment, it is recommended to find a professional maintenance company to come for repair. Big brand companies such as Hong Kong Junhong Electrical Maintenance Company do not recommend unauthorized operations to avoid serious equipment failure or other risks.
