Electrical appliances used for a long time often fail, for everyone, most afraid of summer air conditioning failure, the heat is uncomfortable. When the air conditioner fails, we must find professional maintenance personnel. Although we don't understand it, we should also pay attention to it. In order to avoid their own maintenance mistakes, many people would like to know what precautions are there for air conditioning maintenance?

Check the power supply of air conditioner

When we repair the air conditioner, we need to check whether the contact between the plug and the socket of the air conditioner is normal. If it is found that the air conditioner is hot and hot in the process of operation, it may be caused by the thin power line or the contact between the plug and the socket is not bright, which should be solved according to the actual situation.

Clean the filter screen of air conditioner

We need to clean the filter screen of the air conditioner on a regular basis, preferably once every 2 to 3 weeks. When cleaning, we need to extract the filter screen from the inside of the air conditioner, and then use a dry soft bristle brush to clean the dust on the door, or use clean water to clean the dust on it, and then dry it and install it back into the air conditioner. If you have a large amount of dust inside the air conditioner, you need to clean it more frequently.

Check the air conditioner for water leakage and fluorine leakage

Our household air conditioners are prone to water leakage and fluorine leakage, so we need to pay attention to observe whether there is water leakage at the water pipe connection, and pay attention to whether there is fluorine leakage in the refrigerant pipe of the air conditioner when talking. If there is oil stain around the pipe, it means that there is fluorine leakage, which needs to be handled in time to avoid compressor damage due to too long time.

Clean air conditioner dust

We also need to clean the condenser and evaporator coil of the air conditioner frequently. It is better to use a brush and a vacuum cleaner to clean the dust on the coil. When we need to pay attention, we need to clean the coil in the up and down direction during cleaning. Horizontal cleaning is not allowed to avoid damage to the internal pipeline.

Overall cleaning of air conditioner

If the air conditioner needs to be shut down for a long time due to seasonal reasons, it is better to clean the air conditioner in an all-round way. After cleaning, turn on the fan of the air conditioner to run for about 2 to 3 hours to make the air conditioner dry. It is better to cover the air conditioner with dust cover.
