Maintenance method of Aux central air conditioning without heating fault

1. Troubleshooting of the central air conditioner in Oaks

1. First, check whether the freon in the system is sufficient, whether there is air intake, low pressure, low pressure of fluoride addition, or whether there is a certain air discharge or leakage fault in the system.

2. Whether the system is clean or not, if it is used for a long time, it will produce certain dirt after abrasion in the system, and if it is too dirty, it will block the capillary, so that the refrigeration cycle is blocked, the cooling capacity is relatively small, and the heating effect is not good.

3. There is a problem with the electric control system. When heating, the cooling capacity and heating capacity are switched through the four-way valve. If the electric control system fails, the signal line of the four-way valve stops supplying power, and the four-way valve will not operate, so it will not heat.

4. If the electronic control motherboard is broken, it will not generate heat, so it is necessary to determine whether the electronic control board has input and output, check whether it is the fault of the strong current part or the weak current part, and deal with it accordingly.

5, compressor failure, cross-gas, reduced compression capacity and other reasons will lead to heating or not cooling, if the fault is more complicated, you can only turn to after-sales treatment.

Second, the central air conditioner in Oaks can't maintain the heating

1. The maintenance is not in place, and there is too much dust accumulated on the filter screen of the air conditioner, which hinders the air circulation and leads to the problem that the heat can't be discharged in time, which will make people feel that the effect is poor or not hot enough.

remove the filter screen, then clean it with clean water, and put it back into the air conditioner after drying. However, please note that in the actual cleaning process, don't use washing powder, detergent and other cleaning agents, and you can't bake on the fire. In addition, you should clean the filter regularly to ensure the effect of air conditioning.

2. The temperature outside the room is too low, which causes the air conditioner to consume corresponding energy and frost, which will reduce the power and the heating effect will be worse.

In this case, the external machine can remove the frost manually. If the home is a central air conditioner with water system, you can use a wall-hung boiler, which can not only defrost, but also improve the heating efficiency of the air conditioner and supply domestic hot water, thus achieving multiple goals.

3. Freon is not enough.

Most air conditioners use freon to evaporate into the air outside the room to absorb heat. If Freon does not absorb heat, the air conditioner will naturally stop heating.

in this case, you need to contact a professional for fluorination treatment.

The air leakage of the four-way valve is an indispensable part of the air conditioner. If it leaks, it will not form circulation, so it will not generate heat.

in this case, it is necessary to replace the four-way valve.

3. Precautions for maintenance of Oaks central air conditioner

1. Don't put anything on the outdoor unit of the air conditioner, so as to avoid the noise of the air conditioner. This will seriously affect the life of the air conditioner.

2. The air conditioner should not be turned on and off frequently. Don't turn the air conditioner on and off frequently because the room temperature has reached or exceeded the required value, but let the air conditioner control the start and off through the temperature controller. When the air conditioner is not in use, turn off the power supply and unplug it.

3. There are various grilles on the panel of the air conditioner shell, which are easy to collect dust. You can regularly clean it with soft leather and scrub it with neutral soap not exceeding 4℃. Note that volatile oil, gasoline and acid chemicals should not be used for scrubbing.
