Midea s air conditioner remote control board displays HC, and Midea s air conditioner comfort coolin

Midea's air conditioner remote control board shows that HC stands for defrosting, and the steps to solve it are as follows:

1. First of all, the first step is to check whether the connection line between the air conditioner door switch and the motherboard is broken or whether the plugging is reliable.

2. The next step is to press the switch behind the air conditioning door by hand, at this time, it should be noted that the air conditioning failure can disappear, and then it is explained that the coordination problem between the air conditioning door and the door switch is shown in the figure below.

3. Then it is necessary to unplug the door switch plug, and at this time, pay attention to the grille protection plug on the motherboard to be short-circuited.

4. Then it is necessary to short-circuit the plug of the main board of the air conditioner, at this time, it is necessary to press the switch by hand and use the multimeter to detect the resistance value, if the resistance value is not 0, it means that the door switch is faulty; If the resistance value is 0.

5. The last step is to turn on the remote control of the air conditioner again, and then you can find that there is no HC displayed.

The remote control board of the Midea air conditioner shows that HC stands for defrosting.

When the air conditioner is running in the warm room, after a period of time, the condenser of the outdoor unit will frost a lot and affect the normal heating of the air conditioner, and the air conditioner will automatically enter the defrosting mode (the indoor fan stops) to melt the frost of the outdoor unit. Then heat it normally.

Suggestion: The colder the weather, the more ordinary the frost is, so users can be advised to turn the temperature up a little.

The defrost controller is also an electric switch that uses temperature control contact action, and it is a special thermostat for removing the frost layer of the heat exchanger coil of the outdoor unit during heat pump heating. Its defrosting mode is generally reverse circulation ring thermal defrosting, that is, through the contact of the defrosting controller switch, so that the electromagnetic reversing valve reversing to achieve the effect of defrosting.

- Is the air conditioner malfunctioning? With my 8 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

- Finally, I wish the work to go well, fix the air conditioner earlier, live a happy life——— please give an answer if you think it is good, give a good review, and wish you a better life———

The display of "HC" on the remote control of Midea's air conditioner usually means that the current indoor temperature code is too low or too high, resulting in the air conditioner not working properly. This condition can be caused by the following causes of paraliterin:

The current room temperature is lower than the minimum temperature set by the air conditioner: At this point, the air conditioner cannot start the cooling mode, but instead enters the heating mode to increase the indoor temperature. Try turning up the air conditioner or waiting for the indoor temperature to rise before setting it back. Tardibranch.

The air conditioner is blocked: If the indoor or outdoor unit of the air conditioner is blocked by accumulated objects, dust, or other debris blocking the air vents, then it will cause poor air circulation, which will affect the normal operation of the air conditioner. You can check whether there is any shelter around the indoor and outdoor units, and clean the vents.

The air conditioner indoor unit filter needs to be cleaned: If the air conditioner indoor unit filter is not cleaned for a long time, a large amount of dust and dirt will accumulate, reducing the efficiency of air circulation, and may even lead to air conditioner failure and "HC" error**. It is recommended to clean the air conditioner filter regularly.

If the above methods still do not solve the problem, it is recommended to contact the air conditioner after-sales service center or professional maintenance personnel for inspection and repair.

When the Midea air conditioner remote control board displays"hc", it usually indicates a malfunction of the indoor temperature sensor. This means that the remote control cannot read the temperature information in the room correctly, which may cause the air conditioner to not function properly.

To be solved"hc"Error**, you can try the following steps:

Check the temperature sensor: The room temperature sensor can be affected by dirt or damage, making it impossible to accurately read the temperature of the disturbance roll. You can try cleaning the part around the sensor to make sure it's not blocked or disturbed.

If the sensor is damaged, you may need to contact the after-sales service center or professional technician of Midea Air Conditioner for repair or replacement.

Power off restart: Sometimes, de-energizing your aircon for a while and then restarting it may help resolve temporary errors. You can try unplugging your aircon, waiting a few minutes before plugging it back in, and then restarting your aircon. Slowing down.

Reset the remote: Try restoring the remote to factory settings to make sure there are no wrong settings or configurations. You can refer to the user manual of your Midea air conditioner or contact the after-sales service center to learn how to reset the remote control.
