What to do if the Mijia Air Conditioner displays error code U3?
The Mijia Air Conditioner displays the error code U3, which means that the outdoor unit driver failed when starting. It can also be caused by problems with the outdoor unit electronic control panel and the outdoor unit fan motor. You can try to turn off the power of the air conditioner for about 3 to 5 minutes and then turn it on again to see if it can be restored. If the above method cannot solve the problem, it is recommended to apply for after-sales inspection.
