What should I do if Midea s air conditioner heating does not respond?

1.The four-way valve is broken, and the possible reason is that the four-way valve wire is off, the four-way valve coil is burned out, and the nylon ball inside the four-way valve is blocked. Solution: Replace the four-way valve to solve the problem of air conditioning not heating.

2.The amount of refrigerant in the air conditioner is insufficient or excessive. Workaround:

When the outside temperature is low, the temperature difference with the evaporation temperature of freon is smaller, and the heat exchange effect becomes worse, and the hot air is less. Therefore, if it is an old model, the service life is longer, the wear degree of the compressor is larger, and when the outdoor temperature is below 0, the heating effect of the air conditioner is difficult to be satisfied. In addition, if the nut at the copper pipe horn is not tightened during the installation of your own air conditioner, or the machine has been moved, it can be considered as a lack of fluorine.

Air conditioner fluoride should contact the air conditioner after-sales personnel as soon as possible to solve the problem.

3.There is a problem with the capillary or check valve. Workaround:

Check valves are used in hydraulic systems to prevent the reverse flow of oil or in pneumatic systems to prevent the reverse flow of compressed air. What to do if the air conditioner does not heat due to this reason: Replace the capillary pipe or check valve to solve the problem of the air conditioner not heating.

4.Improper use or maintenance of the air conditioner causes the air conditioner to not heat up. Solution: When using air conditioners for heating in winter, pay attention to the airtightness of the room. If the outdoor unit is frosty and frozen, do not use hot water to defrost and freeze. Stop using the air conditioner and contact the maintenance personnel to check the repair.

This is a device failure.

You can get someone to fix it.

You can also find the after-sales service department.

They can also provide door-to-door service.

Midea air conditioning heating did not respond to the reason:

1. The indoor unit and the outdoor unit are damaged.

The indoor unit of the air conditioner includes an evaporator, a thermostat, a computer motherboard, etc., if these parts are damaged, there may be a situation where the air conditioner can cool but the heating does not respond.

If the air conditioner can be cooled but the heating does not respond, you may wish to check the four-way valve of the outdoor unit.

2. Lack of fluoride. If the air conditioner lacks fluorine refrigeration or heating effect is not very good, the lack of fluorine in air conditioning is also the most common phenomenon, which generally needs to be solved by adding fluoride.

3. The temperature difference between indoor and outdoor is too large.

If the temperature difference between indoor and outdoor is too large, it will also affect heating, especially when the outdoor temperature is relatively low, some air conditioners can not be turned on, this situation is relatively rare, and this situation will generally occur in the case of extreme cold, at this time, the auxiliary heating function needs to be turned on to be used normally.

4. The evaporator and filter are too dirty.

When the air conditioner, evaporator, and filter are too dirty, it will affect the heating effect, and of course, the refrigeration will also be affected. It is recommended that the air conditioner be cleaned every time the season changes.

This kind of problem is relatively common, please check it according to the following steps:

1. After unplugging the plug, plug it back in after a second or two. If you can hear a "drop" sound, it means that the power supply is fine. Conversely, there may be a problem with the power supply.

2. Check whether the remote control of the air conditioner is set correctly.

3. The air conditioner is slow to heat up and produce hot air, which is the same as the wind that is sent out as soon as the car is turned on in the summer, and it is the same as the silver song, you need to wait for the delay and preheating, you need to wait for more than ten minutes to try it.

4. If the indoor unit does not have wind for a long time, check the indicator light on the panel of the internal unit to see if there is any flashing phenomenon. The light flashing is generally a fault display, and the fault condition is indicated according to the number of flashes and offs.

5. If there is still a problem with these exclusions, it may be a problem with the controller, and you can find a local maintenance point to consult for after-sales maintenance.

This situation is indeed there, for example, if your temperature is 20 degrees in summer, at this time you still want him to modulate heat, this time it will definitely not work, unless you adjust the temperature more than 20 degrees, so it will work poorly, on the other hand, you look at it late to see that it is divided into winter and summer, then you can modulate heat in winter, and the other you don't make a mockery when the wind is cold, it will definitely not work.

Reasons and solutions for the failure of Midea air conditioning heating to respond:

1. The air conditioner needs to be cleaned regularly, and the air conditioner is easy to accumulate dust, and when there is too much, it will affect the heating effect of the air conditioner. If the vents of the internal and external units are blocked by dust, the heating effect of the air conditioner will be affected.

Solution: The cycle of air conditioning cleaning is to clean once every three months, mainly to clean the air conditioner's filter and other places, and at the same time, it is also necessary to pay attention to dredging the air conditioner's vent to ensure the smooth flow of the air conditioner vent.

2. The failure of the defrosting controller of the air conditioner will cause the air conditioner to not heat. The evaporator of the air conditioner is in the outdoor unit of the air conditioner, and the failure of the defroster of the air conditioner will cause the air conditioner to be unable to enter the state of defrosting, which will lead to the frosting of the air conditioner evaporator and affect the heating effect of the air conditioner.

Solution: If the defroster of the air conditioner fails, it is necessary to check whether the defroster thermostat of the air conditioner is misaligned, the contacts are stained or the contact is poor. Repairs are carried out after the fault is found.

3. Whether it is heating or refrigeration, the refrigerant is very important, and when the refrigerant of the air conditioner is lacking, the air conditioner cannot refrige or heat normally.

Solution: The lack of refrigerant in the air conditioner will lead to the reduction of the heat exchange efficiency of the air conditioner, resulting in the lack of cooling capacity. When the air conditioner refrigerant is insufficient, it is necessary to check whether the air conditioner has a leakage point that causes refrigerant leakage, and only after the leak point is found can it be repaired and refrigerant added.

4. When the air conditioner is not heating, you can also check whether it is the capillary of the air conditioner or the check valve has a problem, the main function of the air conditioner check valve is to prevent the reverse flow of oil in the hydraulic system.

Solution: When the capillaries and check valves of the air conditioner fail, as long as they are replaced, the situation that the air conditioner does not heat can be solved.

The reason why Midea's air conditioner does not respond to heating may be that the filter screen is dirty, the condenser and evaporator are too dirty, and the voltage is affected.

1. The filter screen becomes dirty

Through the principle of air conditioning, it is summarized that the sequence of air conditioning inlet air is as follows: first, the fan rotates to draw in the air - the air passes through the filter screen - and then blows out through the heat exchanger, so as to realize the function of adjusting the air temperature. However, the indoor air is not clean air, and Lunchai contains a lot of suspended particulate matter (dust), bacteria, etc.

2. The condenser and evaporator are too dirty

The evaporator is a unit operation that uses the heating method to heat the solution containing different substances and non-volatile solutes to a boiling state, so that part of the solvent is vaporized and removed at the same time, so as to increase the concentration of the solution in the solvent. The evaporator is mainly composed of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, promotes the boiling of the liquid and vaporizes the rotten skin, and the evaporation chamber is a component that completely separates the two phases of gas and liquid.

3. Voltage influence:

Too low voltage has a great impact on the use of air conditioners. If the voltage is low, the heating effect of the air conditioner will be significantly reduced, and the wind speed of the indoor unit will also become slow. When the air conditioner is running at a voltage lower than 190 volts, the overload protector in the compressor will be overheated due to the low voltage, which will cause the compressor to overcurrent and overheat the protector.

1. There is a problem with the capillary tube of the air conditioner or the one-way valve of the empty socks. It is recommended to replace the capillary or check valve; 2. The outdoor temperature is too low. If the air conditioner cannot be frosted at a few degrees below zero, it is recommended to use tools to clean the frost and snow on the air conditioner; 3. If the four-way valve of the air conditioner is leaking, it is recommended to replace the four-way valve; 4. If there is dust on the filter screen, too much dust on the air filter, and the vent of the internal and external machine is blocked by foreign objects, all of them can be dredged; 5. If there is a lack of fluorine in the air conditioner, please ask professionals to add fluoride to solve the situation of the air conditioner not heating the situation; 6. Please contact after-sales or professional maintenance personnel for on-site maintenance.

Summary. Hello, 1. The heating power is too small, and the power of the air conditioner does not match the size of the room, so you can replace the air conditioner with more heating power or close the doors and windows of the room. 2. The air conditioner has too much dust, and the air conditioner must be cleaned before using the air conditioner before using the air conditioner.

3. Air conditioner defrosting, the air conditioner will have a defrosting time after turning on the heating function, and the air conditioner will not run during this time period, just wait for a while to finish the defrosting.
