EH 03The indoor fan speed is operating outside of the normal range

Name in the manufacturer's documentation (service manual): The indoor fan speed is operating outside of the normal range[1]

In plain words (editorial)

The indoor fan speed stays outside the normal range, so the air conditioner switches off – connection wires, the fan assembly, the fan motor or the PCB.

When to call a service technician: Call a service technician – the listed parts are inside the unit.
