How to repair the refrigerator computer board, how to repair the refrigerator circuit board

A refrigerator is an appliance that needs to be constantly running, working almost 24 hours a day, so as to keep the food in a cold state and maintain freshness. Then in such a long and efficient working state, the refrigerator will be prone to failure. Today, let's introduce how to repair the refrigerator, and let's take a look!

1. Discharge the capacitor.

Step 1: Unplug the refrigerator or freezer.

Step 2: In order to access the capacitor, remove the repair panel covering the rear of the unit, the removal process will be explained in detail later. The capacitor is located in a housing above the motor compressor unit and looks like a large dry cell battery.

Step 3: To discharge the capacitor, use a 20,000 ohm, 2 watt resistor, which is available at most electronics stores and is very cheap. The probe of the resistor is connected to the terminal of the capacitor to discharge the capacitor.

If the capacitor has three binding posts, connect the resistor to one of the outer and ** posts, and then connect the remaining outer and ** posts. After the capacitor has been discharged, you are ready to make repairs.

2. Disassemble the refrigerator.

The control elements of a refrigerator are usually located on top or top half of it. The motor, compressor, condenser rotor and condenser fan are located at the bottom. In order to access the components in the upper part of the device, remove the set screws or pry open the clips used to secure the plastic panel to the part.

These fasteners may be hidden with a fringe or piping, in which case pry the fringing or piping off with a hard-edged putty knife. Protruding control elements can also be used to hold individual panel components. In most refrigerators, the food rack can be removed to allow access to certain panels.

3. Detect the wire.

If you feel that the wires of your device look frayed, or if you notice burn marks on the plug's prongs or the end screws (the power strip located below the rear access panel of the unit), there may be a problem with the wires. When inspecting wires, set the multimeter to RX1.

Summary. Yes, it can be repaired. If there is a real failure, don't repair it yourself, after all, you are not a professional maintenance personnel, and you don't understand a lot of principles, and it will be even more troublesome if it causes secondary damage.

Let's see if it's within the warranty period, if it's still within the warranty period, then call ** to the after-sales service, or call the maintenance network to report for repair, there is no charge during the warranty period. If the warranty period is over, then it is also recommended that you go to a professional to repair or replace, it is not very expensive and worth repairing.

You've done a great job! Can you elaborate on that?

If the circuit fails, the following checks can be made: 1. If the refrigerator does not run after powering on, you can check whether the fuse is broken, whether the power plug is leaking and whether it is plugged in well, whether the temperature controller contact is closed, whether the heating wire is burned out, etc. Simple problems can be solved by themselves, if it is an internal fault of the compressor, you can call for professional technicians to overhaul.

2. If there is an abnormal sound after the refrigerator is powered on, it will not work normally, so you can use fine sandpaper to polish the contacts and then power on for testing. 3. When the self-opening and self-stop function of the refrigerator is out of control, most of them are faults of the temperature controller. 4. If there is leakage in the refrigerator, you can check the various parts of the circuit system one by one to find out the leakage parts.

The first step to replace the lamp in Meiling refrigerator is to open the refrigerator door and remove the broken bulb from the ceiling at the top of the refrigerator. After picking up the ants, you must be careful when changing, don't touch the thermostat inside, but in the middle of the day, the current refrigerator is generally separated from the bulb and the thermostat. Finally, install and test.

The temperature control computer board of the household refrigerator is broken, and this situation needs to be repaired by the after-sales maintenance personnel of the Bixun Department. Free maintenance during the three guarantee period, and you need to pay for accessories and labor costs outside the validity period of the three guarantees.

Because the problem of the refrigerator involves our household electricity, once the refrigerator is found to have a problem, we need to repair the refrigerator in time, so as to ensure the safe use of electricity in our family. Let's share with you the maintenance methods and purchase skills of refrigerators.

1. Before the refrigerator is troubleshooting, the maintenance process of the refrigerator can be divided into two aspects, one of which is the maintenance of the refrigerator without power, and the other is the maintenance of the refrigerator when it is powered on. When the refrigerator is not energized, the main thing is to check the stability of the parts, whether there is obvious damage, carefully observe whether the pipes of the refrigeration system are cracked, and whether there is oil leakage at the welds.

2. The role of refrigerator compressor for refrigerator is self-evident, and the slippery stool is usually the most likely to cause refrigerator failure. Therefore, when we inspect, we mainly check whether the compressor can operate normally and whether the evaporator of the refrigerator is frosty, etc., which are usually caused by the above conditions.

3. We can also detect the temperature of the compressor, you can test the temperature of the compressor by hand after the refrigerator has been running for a period of time, if the temperature of the compressor is very high, it means that the compressor and other components may fail, which needs to be further checked.

Tips for choosing a refrigerator.

1. Look at the appearance.

When purchasing the refrigerator, it is necessary to pay attention to whether there are concave and convex points in the cabinet, the appearance should be generous and tidy, whether the surface is shiny, whether the door is skewed, and whether there is a feeling of dragging mud and water when pushing and pulling the door.

2. Look at the brand.

Dahui Zaojia knows that the power of the brand is incomparably powerful. Nowadays, the brands of refrigerators on the market are mixed, and we should try to choose big brands and well-known brands when purchasing refrigerators, so that the quality of refrigerators can be guaranteed.

The refrigerator is one of the household appliances that everyone will definitely have in their home, but every household appliance has a time limit for use, and generally during our use, it will definitely give us "little emotions". If it is a more common small problem, we can repair it by ourselves, but if the problem is very large, and no matter how it is repaired, it cannot be repaired, just contact a professional refrigerator repairer! But how many refrigerator repair tips do you know?

Repair Tip 1:

When the refrigerator is not working, you should first unplug the power supply, take a good look at the appearance of the refrigerator to see if there is any particularly obvious damage, and then take a closer look at the small parts in the refrigerator to see if there is any loosening of small parts, take the household repair tools and tighten it. If there are no loose small parts, you should directly look at the refrigeration pipe to see if it is broken, and the above is a simple repair technique for the surface.

Repair Tip 2:

After plugging in the refrigerator latch, carefully observe whether the compressor is often started in response to the letter, generally if the refrigerator starts 5 minutes after a little frost, the cause may be that some systems in the refrigerator are blocked, we just need to deal with those blockages. If the inlet does not freeze, it must be because the current of the compressor has increased, which has burned the refrigerator body and finally caused the refrigerator to not work.

Repair Tip Three:

After the refrigerator is plugged in, listen carefully to whether the refrigerator has a starting sound, when the refrigerator is turned on normally, there will be a starting sound, if the sound is not filial piety, it means that there is a problem. Generally, if there is a gurgling sound inside the refrigerator, it means that the spring in the compressor is broken; If you hear a hissing sound, it means that the refrigerator problem is more serious, and it should be sent to the warranty station for repair at this time, and we can't repair it ourselves; If we hear a humming sound, it means that the compressor is overloaded, and we should check if the compressor is out of order. The above is a detailed introduction to refrigerator repair skills, refrigerators may have various problems, but different problems will have solutions, but it depends on whether we will deal with it.

Nowadays, electrical problems often happen, so we need to master a lot of electrical repair skills, if we master these tips, we can save a large part of the electrical repair costs, and after repairing themselves, there will be a sense of pride and satisfaction, and will make our lives more and more fulfilling, so it is necessary to know more about some electrical repair skills.

If your electric freezer breaks, this can be a very tricky issue, as it means that your food could be ruined at an early age. Here are some basic workarounds you can try to fix it:

1.Check whether the power supply is normal.

Before dealing with any electrical issues, the first thing to do is to make sure that the power supply is working properly. If the refrigerator is not connected to an electrical outlet, it will certainly not work. You need to check that the plug is properly connected to the socket and confirm that the socket is working properly, if you need to replace the power cable.

2.Check the control panel.

If the power supply is fine but the fridge still doesn't seem to be working, then you may want to check the control panel. Some electric freezers may have circuit board failures or control panel failures that render the refrigerator inoperable. Check for errors** on your dashboard, if you need to reset your dashboard, or if you need to change some settings.

3.Check the cooling system.

Another common problem is damage to the cooling system, which can cause the refrigerator to fail to maintain temperature. If your electric freezer doesn't keep your food cool, then you need to check that the cooling system is working properly. It may be necessary to remove dirt or ice from the cooler and cooling pipes.

4.Check the motor or compressor.

If your electric freezer won't turn on or is noisy, it could be a problem with the motor or compressor. It may be necessary to remove the motor cables, replace the motor or compressor.

5.Replacement parts.

If you've ruled out all of the above issues and your electric freezer is still not working, then you may want to consider replacing some appliance parts. This can include electronic components, wires, sensors, assemblies, and more.

In short, when you encounter an electric freezer problem, you need to understand the source of the problem and choose the corresponding method to fix it. If you're not sure how to fix it, it's best to ask a professional to help diagnose and fix the problem.
