1. "E1" fault code appears on the display: this kind of failure is usually due to the communication failure between the outdoor and indoor units. The solution is to check whether the communication line is normal, if there is a problem to be replaced in time.
2. Air conditioning can not be cooled: this failure may be due to insufficient refrigerant or compressor damage. Check the refrigerant amount, exhaust temperature and other parameters, if there is a problem, you need to replace or replenish the refrigerant, or replace the compressor.
3. air conditioning noise: this failure may be caused by loose blades or corrosion of the fan. The solution is to open the machine for inspection and replace the blades or fan.
4. air conditioning can not start: this failure may be due to power outages, controller failure and other reasons. Check the power line, controller, etc., if there is a problem, you need to replace the relevant parts.
5. Air conditioning leakage: this failure may be due to the pipeline connection is not tight, condensation drain clogging and other reasons. Check the state of pipeline connection, condensation drain is clean and smooth, if there is a problem, you need to deal with it in time.
It should be noted that when solving York precision air conditioning faults, it should be handled according to the specific situation, and some faults need professional engineers to check and repair to ensure that the air conditioner can operate normally. At the same time, it is also important to pay attention to regular maintenance and repair to extend the service life of the air conditioner.
