The inverter's power factor correction circuit is experiencing an over-current. This could be caused by high system pressures or a problem with the outdoor fan. The system will attempt to recover, but repeated errors will cause a lockout.
Click steps to track your progress.
Review thermostat and outdoor control for any related high-pressure alert codes.
Moderate errors will clear automatically. Critical errors will clear after the inverter is power cycled.
