EA means an outdoor current-detect fault. The outdoor unit is reporting that it cannot read current the way it expects. That is an electrical fault on the outdoor side, shown on the indoor display. The published step is to note EA, switch the breaker off for a few minutes, and switch it back on. If EA returns, stop resetting it and call support with the code and your model number. The repair is pro-only. Do not measure live terminals or bypass a breaker. Current-sensing faults are for a licensed technician. Tell support whether the code appeared at the first start-up or after the system had been running.
What to do

Sensor, board, fan motor and refrigerant repairs need a licensed HVAC technician. Have your model number and purchase date ready when you call.
