EC 07The outdoor fan speed is operating outside of the normal range (for some models)

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

In plain words (editorial)

The outdoor fan speed stays outside the normal range, so the air conditioner switches off. The manual lists the connection wires, the fan assembly, the fan motor and the PCB.

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