How to measure the quality of the refrigerator s thermostat

It has a fault, there are three states, one is that the switch has been kept closed, the second is that the switch has been kept open, the third is that the temperature can not be accurately sensed or the temperature can not be accurately set, the switch seems to be open or closed normally, but the temperature is high and low. The refrigerator thermostat is a component used in the refrigerator to control the refrigerator refrigeration temperature and adjust the refrigerator refrigeration temperature. So the above corresponds to the three conditions of the refrigerator as follows:

1. The refrigerator compressor continues to work at high load, the sound is non-stop, the refrigerator thermostat is seriously frozen, if the power supply of the refrigerator compressor is not cut off in time after reaching the refrigeration temperature, then the refrigerator will continue, and the high-load work, we can find that the refrigerator noise continues, and the refrigerator is whether it is a freezer or a refrigerator or other variable temperature room. At the same time, the daily power consumption of the refrigerator will increase significantly, and the outside of the refrigerator may also be very hot when working at such a high intensity. These are all symptoms that can occur when the refrigerator thermostat is broken.

2. The thermostat corresponding to the non-refrigeration has kept the compressor in an open-circuit state, no power supply, and the compressor does not work, although the light in the refrigerator is on and there is electricity, but the refrigerator is not refrigerated, which is also an obvious situation. 3. If the refrigerator thermostat cannot accurately identify the temperature or the temperature set by the refrigerator is not executed, then the refrigerator is likely to be hot and cold, for example, we require five degrees Celsius, but the refrigerator is refrigerated to minus ten degrees Celsius, or it automatically adjusts, refrigeration or non-refrigeration, just like the volume switch failure of the radio, the sound is high and low, and the temperature in the refrigerator is also high and low.

There are 3 ways to do this:

1.If the refrigerator's thermostat is broken, it may cause it to not start (not starting in other gears), you can set the refrigerator's thermostat to the highest setting, if it can start, it proves that the thermostat is bad (the highest gear is out of thermostat control).

2.A broken thermostat can also cause non-downtime. (If the refrigerator is refrigerated normally and has been working without stopping, then the thermostat is broken and can be replaced).

3.If the refrigerator has electricity (the light is on), but the compressor does not work, then you need to measure whether the compressor has power supply, if there is no power supply, then it means that the thermostat has no voltage output, you can judge that the thermostat is open, and replace the thermostat.

Temperature from lowest to highest during thermostat 2

The contact has a reaction from on to off. Remove the temperature control connector, test it with a universal meter, adjust the temperature at different temperatures, and find a way to put the temperature control probe into the water at different temperatures to see if the temperature control plays an on/off role because of temperature changes, so that you can know whether it is good or bad.

1. If it is in use, adjust the size, and measure the on/off if you can hear the sound of the contact.

2.If it is new, put the temperature-controlled test head in the refrigerator, leave the adjustment part outside the refrigerator, wait about 10 minutes to adjust it to see if there is a contact sound, if there is a test.

Today, I learned that it is so simple to judge the quality of the refrigerator thermostat in this way.

Refrigerator thermostat.

How to detect good or bad.

1. If the thermostat of the refrigerator is broken, it may cause the macro model not to start (not to start in other gears), you can adjust the thermostat of the refrigerator to the highest gear, if it can be started, it proves that the thermostat is bad (the highest gear is out of the thermostat control).

2. If the thermostat is broken, it can also cause non-stopping. (If the refrigerator is refrigerated normally and has been working without stopping, then the thermostat is broken and can be replaced).

3. If the refrigerator has electricity (the light is on), but the compressor cannot work, then it is necessary to measure whether the compressor has power supply.

Hello, I'm glad you can have your question [heart] [heart] please wait a moment [than heart] [than heart].

1. First of all, adjust the multimeter to the resistance 200 gear, connect the black watch pen to the com jack, connect the red watch pen to the v jack, and finally turn on the voltage switch of the multimeter, pay attention not to press the hold button. 2. The thermostat used in the refrigerator has three or four terminals, one or two of which are grounded, and there is a grounding symbol. The remaining two are the control terminals, and their resistance values should be close to 0 ohms.

3. The normal control contact of the thermostat does not mean that the thermostat is normal, and it is also necessary to measure whether the contact is leakage, at this time, it is necessary to adjust the multimeter to the gear of 20m to measure the resistance value of the contact to the ground. 4. Contact the grounding terminal of the thermostat with one meter pen of the multimeter, and contact one of the control terminals of the thermostat with another meter pen, if the measurement result shows "1", indicating that the thermostat has good insulation and can be used normally.

5. Then use the same method to measure the resistance between the other control terminal of the thermostat and the ground terminal, and display "1."Normal, if the measured resistance is relatively small, it means that the thermostat is leaking, which will cause the refrigerator to trip. 6. The last suspicion that needs to be measured is two connections.

You can remove the refrigerator thermostat and measure the resistance of the thermostat with a multimeter, if the resistance value of the thermostat is large, it means that the thermostat is broken. You can also set the thermostat gear to the strongest gear, if it can be activated, it means that the thermostat group core has been damaged, because the function of this gear is to collapse and excavate the control of the quiet thermostat.

Be cautious in the refrigeratorThermostatHow to judge good and bad:

1. If the thermostat of the refrigerator is broken, the refrigerator will naturally not be able to start, at this time, the thermostat of the refrigerator will be adjusted to high grade, if it still cannot be started, it means that the thermostat is broken.

2. The thermostat is broken, and the refrigerator has been running and cannot be stopped, which can indicate that there is a problem with the thermostat.

3. If the refrigerator still has electricity, but the compressor cannot run, then it is necessary to detect whether the compressor is still supplying power, if there is no power supply, it proves that the thermostat has no voltage output, and the thermostat must be replaced.

How to clean the refrigerator:

1. Unplug the power socket of the refrigerator first.

At the same time to wash the food inside, the refrigerator has compartments, and all drawers must be removed.

2. Clean the compartments and drawers, you can soak them in warm water, and then use dish soap.

Clean it and put it in a ventilated place to dry.

3. Focus on cleaning the inside of the refrigerator, because there may be some oil stains during the cleaning process, which is difficult to remove. We can pour some baking soda.

Its decontamination ability is very good, if it is sterilization, you can pour some alcohol or white vinegar, use some warm water to mix and stir evenly to clean the refrigerator. When cleaning, you must be careful to wring out the rag to prevent moisture from entering the inside of the refrigerator. After drying, wipe the inside and outside with a dry cloth, and then put the refrigerator in a cool place to dry.

4. After the drawer room including the refrigerator is dry, it should be installed in place and plugged in to see if it can work properly. If there is no problem, the refrigerator has been cleaned.

The refrigerator thermostat is an important part of controlling the temperature inside the refrigerator. If the thermostat fails, the refrigerator will not work properly, affecting the preservation and use of food. Here are the detailed steps on how to judge whether a refrigerator thermostat is good or bad:

1.Check the power supply: First of all, you need to check whether the refrigerator is powered on normally. If there is no problem with the power supply, but the refrigerator still does not work properly, the state Chunyin can be considered as a thermostat failure.

2.Check the temperature of the refrigerator and freezer: Open the refrigerator door and touch the temperature inside the refrigerator and freezer with your hands. If you notice that the temperature in both zones is high or low, then it may be because the thermostat is out of order.

3.Adjust the temperature knob: Adjust the temperature knob to a different position and observe if there is a reaction. If there is still no change after adjustment, then it may be because the thermostat is damaged.

4.Measure the resistance value: Adjust the multimeter to the ohmic level and connect the test pen to each end of the thermostat. Judge whether it is within the normal range according to the resistance value range on the manual. If it is not within the normal range, it means that the thermostat has been damaged in the sail hall.

5.Replace the thermostat: If none of the above methods can determine the problem, then the thermostat needs to be replaced. Moriju can remove the original thermostat and install a new thermostat.

It should be noted that when replacing the thermostat, you should choose the same thermostat as the original model and install it according to the steps on the manual. It is also very important to clean the inside and outside of the refrigerator regularly. In daily use, it is possible to carry out a full cleaning and disinfection at regular intervals.

In short, judging and replacing the refrigerator thermostat in time can ensure the normal operation of the refrigerator, prolong its service life, and also ensure the quality and safety of food.

<> judge the quality of the refrigerator thermostat, you need to check the following aspects: refrigerator temperature, heat exchanger, cut-off point, sensor, fuse first stool, connection, interface, etc. Checking for different issues can further determine if the thermostat needs to be replaced or adjusted.

1. Check the temperature: Measure the temperature of the refrigerator through a thermometer and other tools, if the temperature is abnormal or the temperature fluctuates greatly, it may be a problem with the thermostat.

2. Check the components: check whether the heat exchanger, cut-off slot, sensor, fuse, connection and interface in the thermostat are damaged, poor contact or broken lines.

3. Check and adjust: Modify the parameters by adjusting the knobs or buttons in the thermostat, observe the working status of the refrigerator, and confirm whether the parameters are consistent with the actual situation, so as to judge whether the adjustment of the thermostat is normal.

Expand your knowledge: If the refrigerator has abnormal temperature, abnormal operation, abnormal power consumption, etc., you need to actively investigate the problem of the thermostat and carry out maintenance and maintenance in time. At the same time, it is also necessary to pay attention to measures such as controlling the power load and relieving the use load in the use process to avoid excessive pressure on the thermostat and electrical system, so as to improve the service life and stability of the refrigerator.

Tool material: multimeter, temperature control switch.

01 Adjust the multimeter to the 200 level of the electric's code resistance, and then turn on the voltage switch of the multimeter.

02 The thermostat used in the refrigerator has two control terminals, and its resistance value should be close to 0 ohms.

03At this time, it is necessary to adjust the multimeter to a gear of 20m and measure the resistance of the contact to the ground.

04 Touching one of the control terminals of the thermostat with a pen of the multi-purpose socks watch, the measurement result shows "1It can be used normally.

05 Then use the same method to measure the resistance between the other control terminal and the ground terminal of the thermostat, and display "1"It's normal.

06 Finally, measure whether the resistance between the two ground terminals is close to 0, if the resistance value is 0, it can indicate that the first two terminals can be used.

Detecting whether the refrigerator thermostat is damaged can be done according to the following methods:

1.Observe the operating status of the refrigerator: If the temperature in the refrigerator and freezer compartment cannot reach the preset temperature when the refrigerator is running, there may be a problem with the thermostat.

2.Use a thermometer: Place a thermometer in the freezer and a refrigerator to record the change in temperature separately. If the thermostat is damaged, it will not be able to control the temperature of the refrigerator properly, causing the temperature to cross the bridge or be too low.

3.Check the status of the refrigerator light: When you open the refrigerator door, if you find that the refrigerator light is not as bright as the sensitive band, this is also a sign that the thermostat may be damaged.

If the above methods detect that there is a problem with the thermostat, it is recommended to contact a professional in time to repair or replace it.

To detect if your refrigerator thermostat is damaged, you can follow these steps:

First, turn the refrigerator temperature to the lowest setting and wait for a few hours for the temperature inside the refrigerator to reach its lowest point;

Then turn the refrigerator temperature to the highest setting, wait for about 10 minutes, and observe the temperature change inside the refrigerator;

If the temperature inside the refrigerator does not change significantly after a period of time, there may be a problem with the thermostat and needs to be further checked or replaced. In addition, a multimeter can also be used for testing, but it requires certain electrical knowledge and professional tools;

If there is an uncertain situation and potential safety hazards in the closed meditation fruit, it is recommended to find a professional for maintenance and testing, and do not operate it by yourself. At the same time, in daily use, the refrigerator radiator should always be kept clean and clean, so as not to affect the refrigeration effect.

To detect whether the thermostat of the refrigerator has been damaged, you need to use a multimeter, express the multimeter to the normal detection function, and use the two probes of the multimeter to connect the two power ports of the thermostat, if the multimeter does not display instructions. The thermostat has been damaged, if there is no multimeter at home, you can adjust the temperature of the ice extermination box to the highest temperature setting, if the refrigerator has been in the refrigeration and bending state of the world, it will not automatically stop, indicating that the thermostat of the refrigerator has been damaged.
