What should I do if the air conditioner shows that the dust is full and I don't cool it?

If the display screen of your air conditioner shows "dusty" or "filter screen needs cleaning", you need to deal with it in time to ensure the normal operation of the air conditioner.

First of all, how to deal with dust?

1. Clean the air conditioning filter.

First, turn on the air conditioner after shutdown and take out the filter. Then gently clean it with a soft brush and clean water, then dry it (be careful not to be in direct sunlight) and put it back. You can clean the air conditioning filter regularly, and it is generally recommended to clean it once a month.

2. Replace the air conditioner filter.

If your air-conditioning filter has been used for a period of time, it still has dust after cleaning, or it has been deformed and damaged, so you need to replace it. Before replacing it, please check which filter is needed for the air conditioner model.

Second, how to deal with it without refrigeration?

1. Check the cooling function of the air conditioner.

First, observe whether the outdoor unit of the air conditioner is turned on after it is turned on. If the outdoor unit responds, it can be judged that there is no problem with the refrigeration function of the air conditioner. It's time to check the indoor unit.

2. Check the indoor unit of the air conditioner.

If there is nothing wrong with the indoor air conditioner, it is necessary to check whether there is fluorine leakage in the indoor air conditioner and pipes. If there is fluorine leakage, it is necessary to recruit professional air-conditioning maintenance personnel to deal with it. If there is no fluorine leakage, it is necessary to continue to check the air conditioning circuit, compressor and other problems.

In short, if the air conditioner shows that it is full of dust and does not cool, it is necessary to check whether the filter screen of the air conditioner is blocked and clean it. If the filter screen is blocked, it can be cleaned or replaced. If it is ensured that the filter screen will not cool down after cleaning, it is necessary to check the outdoor unit and indoor unit of the air conditioner to see if there is fluorine leakage or other faults, so as to determine the faults, find out the causes in time and maintain them in time.
