The air conditioner won t turn off when it s on

This is because the Midea air conditioner has a drying and mildew prevention function, the drying and mildew prevention function is to shut down in the refrigeration, dehumidification, and automatic (refrigeration) mode, and the air conditioner continues to run in a breeze for 10 minutes (at this time, the dry and mildew prevention pattern is bright) to blow out the moisture in the evaporator to prevent the evaporator from accumulating water and mildew, and blowing out odor gas.

It may be that the control switch on the main board of the air conditioner has not been used for a long time and is rusty, resulting in a short circuit of the switch, and it is not directly connected through the switch line. You can try to gently flip the air conditioner emergency switch back and forth a few times (it must be when it is turned off), it should not be a big problem, and you can solve it yourself.

1. The remote control battery is dead, try to replace the battery.

2. The remote control is damaged and cannot send a signal.

3. The receiver of the air conditioner is damaged.

4. There is an error in the remote control program.

5. The drying function may be turned on, and the machine will still work for a period of time after it is turned off.

An air conditioner is an air conditioner. Refers to the process of adjusting and controlling parameters such as temperature, humidity, cleanliness, speed of ambient air in building structures by artificial means.

Generally, it includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal device and other major parts and other auxiliary equipment. It mainly includes pumps, fans and piping systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically process the air and temperature to make the air parameters of the target environment meet the requirements.

Is yours a cabinet or hang-up, or a ceiling machine? If you hang up, if there is no problem with the remote control! If there is no problem, there is a problem with the receiving circuit of the machine!

It may be garbled code, you unplug it, or just turn off the power switch of the air conditioner, wait for a few minutes before turning on the power to see if it is normal.

The air conditioner indicator is out of order.

Is it a remote control or a manual one?

The air conditioner could not be turned off for the following reasons:1. The remote control is out of power or damaged, and you need to replace it with a new battery or parts.

2. If the motherboard is faulty, you need to contact a professional to deal with it.

3. If you turn on the drying and mildew prevention function, you need to change the mode to "healthy" mode, and then press the "on/off" button to turn on the machine, and then turn it on after 5 seconds to return to normal. Common faults and maintenance methods of air conditioners:

1. Water leakage of air conditioner, which is one of the most common faults in daily life, about 5 out of every 10 air conditioners will leak. This is mainly caused by the blockage of the drain pipe, as long as the drain pipe is cleaned in time, the leakage problem can be effectively solved. Vertical nucleus.

2. There are many reasons for the failure of the air conditioner noise, the first installation is not firm, and it needs to be reinstalled. Second, there is a problem with the fan blade of the external unit, and a new blade needs to be replaced in time. Third, the compressor itself is faulty and needs to be repaired or replaced with new equipment.

The reason may be that the remote control is out of power, which can be solved by replacing the battery. The cause may be that the motherboard is faulty, which can be solved by replacing or repairing the motherboard. The reason may be that the drying and anti-mildew function is turned on, which can be solved by changing to healthy mode.

1. Remote control for air conditioner.

If the battery is dead or damaged, the air conditioner will not turn off. In this case, it is necessary to replace the battery of the same model or replace it with a new remote control. If the aircon motherboard fails, it needs to be repaired or replaced.

2. If the air conditioner turns on the drying and mildew prevention function, the air conditioner will not be turned off. At this time, you need to change the mode to health mode, and then press the on/off button for 5 seconds before turning it on, and the air conditioner will return to normal. 3. Regular maintenance and maintenance of air conditioners can improve the efficiency and service life of air conditioners.

Summer is the peak period for the use of air conditioners, so it is necessary to clean the filter of the air conditioner every two weeks, and regularly count the materials to dredge the debris in the pipes of the outdoor unit to ensure the smooth drainage of the air conditioner. 4. When cleaning the filter screen of the air conditioner, the first thing to do is to put the air conditioner panel.

Turn it on, then take out the filter of the air conditioner, soak the filter in the cleaning agent for about half an hour, and then use a soft brush to brush off the dust on it and dry it naturally, and then you can reinstall it back into the air conditioner. Crack the world.

Summary. Dear, hello, I'm happy to answer your questions, the reasons why the air conditioner can't be turned off and can't be turned on are as follows:1

It may be that the receiver on the air conditioner panel is not aligned, resulting in not really turning off, check if there is still a temperature display on the remote control, if there is an indication that it has not turned off successfully. Point the remote at the air conditioner and press the on/off button again until the remote control no longer displays the temperature either. 2.

It may be that the air conditioner is running the defrost function or the drying and mildew prevention function, and the air conditioner will be automatically turned off after waiting for about 10 minutes to run.

I'm sorry I don't understand, but can you elaborate on that?

Dear, in addition, the air conditioner is not turned off for the following reasons: 3It may be that the air conditioner system is faulty, unplug the power supply of the air conditioner, wait for a few minutes and then plug it back in, or turn the air conditioner on and off again to see if it can be restored.

4.It may be that the baffle of the air conditioner outlet has been hit by an external force, resulting in the deformation of the wind baffle and cannot be completely closed, so it is best to contact after-sales workers for maintenance. Hope it can help you and have a happy life!

The air conditioner can't be turned off and can't be turned on, how to check whether the remote control is set to a timer in advance 2 Make sure that the air conditioning unit has electricity (whether there is electricity on the socket), see if the air switch is turned off (the external unit is faulty or tripping caused by electrical failure) 3 After determining that there is electricity, set the remote control to the windshield (the external machine is not open), see if the internal fan can be rotated, if the internal fan is running in the windshield of the remote control, it means that the internal machine is good. Press the remote control button, and there should be a "beep" sound on the inner unit. If it is normal, set it to heat up again.

Look at the external unit, the external unit should be dismantled and should be run first, and then the indoor unit should be run again to produce hot air. If the external unit moves together, jump the air and turn it off, indicating that the external compressor is faulty.

Reason: First, the air conditioner is not turned off properly, and the motor gear is not reset, so the air conditioner cover is not closed, which can be closed by manual pull.

Second, the air conditioner cover pendulum motor or air conditioner cover gear is broken.

After the air conditioner lid is opened, close the method:

1. Turn off the air conditioner and cut off the power supply.

2. Press and hold the recessed parts on both sides of the air conditioner with your hands to open the shell of the air conditioner.

3. Aim at the recessed parts on both sides of the air conditioner and press down firmly.

4. After the concave and convex parts of the air conditioner are fully docked, make sure that the closure is completed, and you can do it.

5. Unplug the plug and wait for more than ten seconds before Xinxiao plugs it in, if it still can't be the control circuit or motor is broken.

If you don't know how to be honest, don't move by yourself, you should find a professional maintenance staff or go to the maintenance center, and let the maintenance master deal with it, so as not to cause unnecessary trouble!

Hello dear users, If your air conditioner won't turn off, here are some possible solutions:1Check if the battery of your air conditioner's remote control needs to be replaced.

2.Make sure the air conditioner switch is powered off, and you can unplug it or turn it off. 3.

Try restarting your air conditioner system. The method is to completely de-energize the air conditioner and then restart it. You can do this by looking for the switch or unplugging it on the air conditioner.

4.Check that your aircon is set up correctly. This may include setting the wrong temperature, timer or mode, and so on.

What is going on when the air conditioner is turned on and can't be turned off Hello dear, the air conditioner does not stop, there are two possibilities: 1There are many temperature sensors that need to be used on the air conditioner, among which the indoor temperature sensor is related to the "shutdown", which is installed on the air conditioner.

The air conditioner needs to receive the signal from the indoor temperature sensor and automatically shut down when the indoor temperature reaches the set temperature. If this temperature sensor fails, the air conditioner thinks that the room temperature has not reached the set temperature and turns on the compressor to cool it all the time. (In addition, another possible consequence of a malfunctioning indoor temperature sensor is that the outdoor unit never starts – because it tells the air conditioner that the indoor temperature has reached the user's set temperature.)

The temperature sensor is faulty and does not affect the air conditioner refrigeration. So when the air conditioner is not down and it's getting colder and colder, you have to start to wonder about the temperature sensor. 2.

Problems in the refrigeration system Air conditioning refrigeration requires a complete set of systems, and any problem in any link will lead to the decline or even disappearance of the air conditioning refrigeration capacity. When the air conditioner loses its cooling capacity, the indoor temperature will never reach the set temperature. The air conditioner can't receive the "temperature is low enough" signal from the temperature sensor, and the stove will naturally not shut down.

When the air conditioner does not stop and the indoor temperature does not drop, it is time to start to suspect the problem of the refrigeration system. Hope it helps.
