Can the Midea refrigerator 551 defrost heater and 536 heater be intermodal?

The businessman's wife can use the general voltage running light, but the speed of the upper child is slightly faster and slower.

The defrosting circuit is only available in air-cooled refrigerators, which are also known as frost-free refrigerators, but in fact, they do not need to be manually defrosted.

Hello, you can only buy large and not small for this pipeline, and generally there are regulations on how big it is better.

Yes, no problem.

However, you need to consider whether the installation interface is universal.

Yes, it can be used, and it will take a long time, so it is recommended that you can heat it up with a heater, otherwise there is no way to use it for a long time.

In the life of modern society, household appliances are already a necessity. As a long-term refrigerator for every family, it is a matter of 10 years to choose a good one, so it needs to be considered comprehensively.

Let's talk about it today, how about Midea refrigerators, Midea refrigerators and Haier refrigerators, which brand of refrigerator is more worth buying!

A beautiful refrigerator brand introduction.

Second, how to buy a refrigerator in the United States.

Sanmei refrigerator recommended.

Four. Which one to choose, Midea refrigerator or Haier refrigerator.

A beautiful refrigerator brand introduction.

Midea refrigerator is a subsidiary of Midea Group and a product of Midea Refrigeration Appliances Group. Midea Refrigeration Appliances Group has always been committed to the cultivation of brand, skills, services, quality, etc., insisting on the company's competitiveness, air conditioners, refrigerators, washing machines and other commodities have always insisted on continuing to develop steadily. Nowadays, the company's products have a very high market share in China.

The production of Midea refrigerators is done in strict accordance with the production inspection process, and with excellent production skills, Midea refrigerators still occupy a place in China. Nowadays, refrigerator brands in the domestic market are fighting for strength and quality, so Midea refrigerators still have a certain advantage. However, because most of Midea's products are subordinate, refrigerators are not as well-known as air conditioners, rice cookers, washing machines, etc., so they still need to improve.

From the perspective of energy saving, energy efficiency and environmental protection of goods, Midea refrigerators are still very good.

Second, how to buy a refrigerator in the United States.

1. Look at the refrigerator model.

When buying a Midea refrigerator model, you must pay attention to the refrigerator freezer model, and then choose a Midea refrigerator that is suitable for your own use. Whether it is a single door or multiple doors, large capacity or small capacity, the freezer models of Midea refrigerators are all refrigerated and frozen models. The refrigerated and frozen freezer model can well realize the dual-purpose of one machine, store food according to needs, and meet the different storage needs of users for food refrigeration and freezing, which is very convenient.

2. Look at the refrigerator refrigeration method and door structure.

When we buy refrigerators, we can all have a good understanding of the refrigeration method of a certain brand of refrigerator, and then choose the style and door structure of Midea refrigerator. The style, capacity and size of Midea refrigerators are different, and the refrigeration methods are also different from direct cooling, dual temperature, and air cooling. Each refrigeration method is tailored to the possible use, size, and overall layout design of the refrigerator, and strives to achieve the results.

According to the door structure, Midea refrigerators can be single-door, double-door, side-by-side, three-door and multi-door refrigerators, and the more doors of the refrigerator, the larger the capacity.

If it still doesn't work to change the refrigerator defrost heater, then check whether the frozen capillary is leaking, if the problem is here, re-add the freezing night and weld it.

Measure the current to see if there is any refrigeration.

Or is it a problem with the temperature sensor, or it is not installed properly.

Organic can be replaced with curling irons, and if you add it, the disease will hurt faster and more violently.

The defrosting heating tubes of air-cooled refrigerators are installed in the lower part of the evaporator, individually and on the evaporator pipes.

The defrosting circuit is only available in the air-cooled refrigerator, which is also known as the frost-free refrigerator, in fact, it does not need to be manually defrosted rather than really frost-free, and the defrosting circuit is to play the function of automatic defrosting for the refrigerator. The defrosting timer is the original that controls the work of the defrosting heater, it calculates the working cycle of the compressor, generally the defrosting command will be executed after the compressor works for 8 hours, and the defrosting timer will supply power to the defrosting heater to achieve the defrosting function, and the compressor does not work at this time.

1.Defrosting timer (cumulatively calculate that the compressor works for 17-24 hours and then disconnect the power supply of the compressor and supply power to the evaporator, water connection trough and hot wire);

2.evaporator heating wire (evaporator heating defrost); You say, defrost heaters.

3.Sink heating wire (sink heating defrost);

4.Defrosting thermostat (controls the temperature during defrosting);

5.Bimetal or temperature insurance (a protective device to prevent the failure of the defrosting thermostat), it is generally broken if the frost-free refrigerator is not refrigerated. ）

Working principle: the defrosting timer calculates the compressor to stop the power supply to the compressor and the circulating fan after working for 17-24 hours, and at the same time supplies power to the evaporator and the heating wire of the water tank after the defrosting thermostat and temperature insurance, and disconnects the power supply to the heating wire when the defrosting thermostat monitoring reaches the critical point (the temperature at which the defrosting thermostat is located) (if the defrosting thermostat reaches the critical point and is not disconnected, the temperature insurance will be overheated and disconnected) to end the defrosting process, and then the timer resumes the power supply to the compressor, And delay a few minutes to power the circulating fan, and re-cooling begins.

All for defrosting, but one is freshly made and the other can be set to work.

The smaller the number of the refrigeration level of the Midea refrigerator, the higher the temperature, and the higher the number, the lower the temperature.

The knob of the thermostat is marked with a number such as , which indicates the grade of temperature, not the actual temperature.

Extended Resources:

1. The dividing point between air cooling and direct cooling is about 300 liters, and large-volume multi-room air cooling has the advantage.

Second, the volume is large, there are many compartments, and air cooling has an absolute advantage in the distribution of cooling capacity. If direct cooling is used, there will be technical obstacles, and it is not easy to achieve. The 3 direct cooling compartments are basically at the limit, and if you want to make more compartments, you will sacrifice some performance.

So don't believe some of the most spacious multi-compartment (or even drawer-door) direct-cooling refrigerators on the market.

3. The air-cooled refrigerator has more air supply from the fan, so the indoor temperature of the refrigerator is relatively average, there is no great temperature change, and the refrigeration effect is naturally excellent, but also considering the role of the fan and the complex circuit design, the air-cooled refrigerator is much higher than the direct-cooled refrigerator in terms of energy consumption and noise.

Fourth, because there is no electric fan, the direct cooling type will not produce additional noise and power consumption, and will not cause drying on the surface of the food due to blowing.

5. Air cooling is due to the forced circulation of cold air, so the cooling speed is fast and the temperature balance is good, which is its inherent advantage, and direct cooling cannot be compared. However, due to the natural convection, the temperature balance is relatively poor, and the cooling rate is relatively low.

Sixth, the inherent defrosting cycle, fan and multiple compensation heaters inside the air cooling, resulting in higher power consumption and noise than the direct cooling refrigerator, so in a similar situation, air cooling must not have advantages in these two aspects, look at the national and international refrigerator performance and energy consumption level standards to understand this. Therefore, it boasts that air cooling has lower energy consumption and less noise than direct cooling, but it is not compared under the same conditions.

Seventh, the manual defrosting of direct cooling is really annoying, the so-called micro-frost design is just the use of the whole drawer for freezing, reducing the air flow in the door opening box to reduce frosting. Even so, it is generally necessary to defrost for half a year, and if the number of doors is rarely opened, it can be extended, and vice versa. If the door seal is not good or aging, the frost will also become severe.

The number of defrosts will increase with longer use time.

8. Due to the forced circulation of air cooling, the smell will be channeled in all rooms. Dual-system air-cooled refrigerators have begun to become popular, separating freezing and refrigeration, and the situation is better.

9. The air-cooled refrigerator constantly brings the moisture in the box to the evaporator, and then flows away when it is defrosted, which brings dry consumption in the box, which is not conducive to preservation, which is also the inherent disadvantage of air cooling. Although there are some so-called preservation techniques, they are just in a small area (such as a relatively sealed space), not allowing cold air to enter, only flowing through the surroundings, and the space is actually close to natural convection, but it is just direct cooling in a small space.

1. The smaller the number, the higher the temperature, and the larger the number, the lower the temperature. In summer, it is generally enough to adjust to about 3 gear, and if there is little food, you can also adjust to 2 gear. In winter, it is generally adjusted to about 4 gears, and you have to look at the food in the refrigerator, if there are many things, turn it down a little, and if there are few things, turn it up a little.

2. The refrigerator is usually equipped with a thermostat, some of which are operated through the control panel outside the refrigerator, while some are adjusted by adjusting the internal section of the temperature. The external control panel only needs to be adjusted to the desired temperature, while the internal thermostat is the higher the setting, the lower the temperature inside the refrigerator.

3. Under normal circumstances, after the freezer reaches -18, it is very difficult to drop by 1, if it is continuously kept below -24, the refrigerator will increase a lot of energy consumption, and at the same time, the compressor will run for a long time or even without stopping due to the large temperature difference between the inside and outside, and the loss of cooling capacity.

The bigger it opens, the bigger the fresh-keeping layer will freeze.

The higher the number, the colder the temperature, and generally it can be on 4, don't get it to 7, otherwise it won't stop.

The resistance of the frost-free refrigerator is about 350 ohms.

Frost-free refrigerators do not automatically frost:

1 Check if the fan is working properly. Frost-free refrigerators rely on air circulation, if the fan does not rotate, the cold air can not diffuse and circulate, which will affect the refrigeration effect of the refrigerator. As a result, the temperature of the refrigerator cannot be lowered, and the refrigeration effect is not good.

2. Check whether the defrosting circuit is in good condition, whether the measurement temperature limit fuse is in good condition, and whether the defrost heater is open.

3. Remove the defrosting timer to check and measure whether the timer motor is broken; Whether the power-up test is used ** such as.

Generally around 300 euros, new parts should be preferred.

There are many reasons for non-defrosting failures, which should be investigated one by one:

Broken wire of defrosting heater; The fan motor is damaged; The temperature sensor switch fails; defrost timer failure, etc.

If it is implemented on the defrost heater, it should be replaced, which is a universal part and does not need to consider the resistance value.
