Midea air conditioner doesn t heat up in winter

Reason 1 for not heating.

Air conditioning heating is normal, but the applicable area of air conditioning heating is smaller than the area of the room using air conditioning, for example, 50 machines (2 horses) should be used, 35 machines (horses) are used, and the room temperature cannot go up, that is, the amount of customized heat is not enough.

Solution: Use cloth curtains and spray-painted portrait partitions to reduce the room area.

Reason 2 for not heating.

There is no fault in the air conditioner, because the outdoor temperature is below 0 degrees, which affects the heating effect of the air conditioner. The lower the outdoor temperature, the worse the heating effect of the air conditioner, that is, the actual heating is not enough.

Solution: Use a fan or heater at the same time when using an air conditioner.

The third reason for not heating is three.

The fixed-speed air conditioner itself heats normally, but the auxiliary electric heating is not turned on, and some of the heating is missing.

Solution: Turn on the auxiliary electric heating at the same time when the fixed-speed air conditioner is heating.

Reason 4 for not heating.

The heating of the air conditioner is normal, but the filter of the indoor unit of the air conditioner has not removed the dust for more than half a month. Dust clogs the filter, causing a decrease in the amount of circulating air, i.e. not enough heat is blown out.

Solution: Clean the filter of the indoor unit of the air conditioner every half a month.

The reasons why the air conditioner does not heat: 1. Dust accumulation on the filter screen; 2. Fluoride deficiency; 3、Check valveand four-way valve failure.

1. The filter screen of the air conditioner is not cleaned up dust, the air conditioner is basically out of use after being used in summer, and few users will take the initiative to clean the filter screen, and there is more floating dust in the dry room in autumn and winter.

2. Freon.

Not enough, this is the most common air conditioning failure problem, generally found in the summer freon less affects the refrigeration effect, but the long service life of the air conditioner and frequent use will lead to the reduction of freon, the heating cycle function is greatly reduced, at this time find a professional to add fluoride.

3. The check valve and the four-way valve are faulty, and now many air conditioners are heat pump type, and the check valve is used to switch the refrigerant.

If the check valve fails will cause the resistance of the refrigeration system to decrease, so that the air conditioner condenser.

If the heat cannot be obtained, there will be insufficient heating, and the four-way valve string will also reduce the heating function, and the check valve or four-way valve can be replaced.

You can click the link below or call the official ** to make an appointment with a professional maintenance master in the same city to repair and deal with it for you.

What happens if the Midea air conditioner does not heat up in winter: the filter screen is not cleaned up the dust: the air conditioner is basically out of use after being used in summer, and few users will take the initiative to clean the filter, and there is a lot of floating dust in the dry room in autumn and winter.

Insufficient freon: This is the most common problem of air conditioning failure, generally found in the summer freon less affects the refrigeration effect, but the long service life of the air conditioner and frequent use will lead to the reduction of freon, and the circulation function of heating is greatly reduced.

Check valve and four-way valve failure: now many air conditioners are heat pump type, the check valve is used to switch the refrigerant circulation, if the check valve fails, the resistance of the refrigeration system will be reduced, so that the air conditioning condenser can not obtain heat on the heating insufficient, and the four-way valve string gas will also reduce the heating function, replace the check valve or four-way valve.

This answer is applicable to Midea KY-15 N7Y-PHA and Midea KYR-35 N1Y-PD2 brand air conditioner models.

In the process of using air conditioning products, there will be no heating or refrigeration, one is related to the service life and service life, more is directly related to the daily maintenance is not in place, the following is what I sorted out the beauty of the air conditioner does not heat up, welcome to read.

Midea air conditioner doesn't heat what's going on

What are the main reasons for Midea's air conditioner refrigeration is normal, but Midea's air conditioner is not good in winter?

Generally speaking, whether Midea air conditioning heat is good or not is related to the size of the house, the degree of sealing, the outdoor temperature, etc., and the air inlet temperature and outlet temperature of Midea air conditioner will be different by 10. For example, when the air conditioner is not used, the indoor temperature is 5, then the air outlet temperature of the Midea air conditioner after heating is 15. At this time, even if you use the remote control to put the beauty'The air conditioner temperature is set at 30, and the air outlet temperature can only reach 15 these days.

In addition, turning on the hot air conditioner in winter is not the higher the better, and the higher the less you will catch a cold. The room temperature is best at 18-22, the Midea air conditioner can make the indoor air dry and gray, which will have a negative impact on the **, it is recommended that the Midea air conditioner is turned on to 25.

If the outside temperature is lower than 0, the heating effect of the air conditioner will definitely not be good. Because when the outside temperature is lower than 0, the outside unit of the Midea air conditioner will be frosty. Then when the Midea air conditioner is turned on for heating, about 8-12 minutes will be used for "defrosting", and at this time, the room temperature may be lowered.

Precautions

If the air conditioner is idle for a long time in winter, the filter should be cleaned to avoid dust accumulation and affect the next use. If the filter is too dirty, it can be washed with water or neutral detergent, but it should not be cleaned with hot water above 50 or strong alkaline and acidic liquids such as washing powder, gasoline, banana water, etc., so as not to deform.

Be careful not to use too much force when cleaning the panel, you can use a neutral detergent diluted by water if the dirt is heavy, wring out the water in the cloth first, and then wipe it, and thoroughly wipe the detergent on the case after cleaning. Select the air conditioner function key in"Air supply status"Run for 3-4 hours to let the moisture inside the air conditioner dry and keep the inside of the air conditioner dry. Then turn off the air conditioner and unplug it.

And take out the battery in the remote control to avoid battery leakage and corrosion of internal components.

Clean the outdoor radiator, do not insert it with sticks, otherwise the fan will be stuck or damaged; If the outdoor case cannot be wiped with a cloth, you can use a lightweight, cleaner mop to clean it. Carefully remove the panel, scrub it with a soft cloth, and gently brush the heat exchanger of the indoor unit with a small brush. Then cover the chassis with a cover to prevent dust accumulation from affecting the normal operation of the machine.

However, it should be noted that since the heat sink is a thin aluminum material, it is easy to deform after being stressed, so it should be carefully brushed.

1. The use environment and use methods should be appropriate

Do not switch on and off the air conditioner, if an air conditioning switch, it has an impact on the life of the air division, and it will also affect its heating effect.

2. Dirty mesh may lead to poor heating effect.

The net of the air conditioner is the most dusty component, it is recommended to clean the net once every two weeks, the net is not cleaned for a long time, which will cause the filter to be plugged, so that the green capacity will be reduced, and then the amount of the airbox ring will be reduced, which will affect the thermal effect.

Therefore, it is necessary to wash the net frequently, do not touch the whole part of the indoor unit when disassembling the net, be careful to be scratched by all, wipe the dust with a dry cloth, and if the net accumulates too much work, you can wash it with clean water, but do not wash it with hot water, if the water is too hot, it may cause the deformation of the net.

3. The Taiban of the cooler and evaporator will also affect the heating effect.

In the components of the air conditioner, the condensation and evaporation of the heat sheet pay attention to the protection of Shanghai, if the cold doubt, evaporation dust too much, will also reduce the heat exchange effect, the derivative air division heating capacity is insufficient. For the protection of the heat sink, we should be more careful, remove the dust on the cooler every three months, do not touch the heat sheet, remove the machine every year, pump the lubricating oil into the motor, and remove the dirt on the surface of the special refrigeration system.

4. The influence of voltage should not be underestimated.

If the voltage is too low, there may be a phenomenon that the machine is turned on for a long time and the temperature still cannot go up, at this time you should choose a stable voltage and try the air conditioner again. If the voltage is normal and the air conditioner still does not heat, it is necessary to consider the reason for the electric auxiliary heating element.

5. Check whether the electric auxiliary heating function is effective.

At present, many people use heat pump electric heating hybrid air conditioner, they are generally used with electric auxiliary heating technology, if the electric heating system appears, there will also be insufficient heating, if you find that the outdoor temperature above 5 heating is normal, in the outdoor below 0 heating is insufficient, you can judge that the electric heating system is faulty, you should carefully check the electronic wire and electric heating device.

6. Usual maintenance and use methods are very important.

For the maintenance of the air conditioner, first of all, it is recommended to clean the filter diligently, it is recommended to clean it every two weeks, and the condenser is cleaned every month, and the motor is checked once a year, which is useful for prolonging the life of the air division.

Hello dear. Glad for your question: Midea air conditioner does not heat the original Ant Duan Yan because of the following:

1. It may be that the setting mode is wrong, such as adjusting to the refrigeration mode Ranchang, when this problem is solved, then press the remote control to the heating and adjust the temperature. 2. When there is a lack of fluorine inside the air conditioner, it will also lead to no heating, and freon should be supplemented in this case. 3. It may be that the air conditioner filter is blocked and plugged, causing the air conditioner to not heat, so you should clean the filter in time.

1) Fluorine leakage at the connecting pipe joint;

2) The wiring is incorrect;

3), fuse burning;

4) The compressor is faulty;

5) The outside environment temperature is high, and the indoor personnel are more beautiful air conditioners.

operating at full capacity.

6) The power supply voltage is too low, which causes the Midea air conditioner to be difficult to start, and then stops or the fuse blows after starting, so it is recommended that the user install a power regulator.

7) The air outlet of the air outlet is not large when the temperature does not drop in the strong cold room, which is because the air filter has too much dust, and the filter is cleaned.

8) Thermostat.

Improper adjustment.
