If the Mijia Air Conditioner displays PA, it means fluorine deficiency protection/refrigerant cycle abnormal protection. You can try to turn off the power of the air conditioner for about 3 to 5 minutes and then turn it on to see if it can be restored. If the above cannot solve the problem, it is recommended to apply for on-site inspection by after-sales service
