Daikin- E7 error code

[qazman]

Hi.
The Daikin air conditioner that we own stopped working all of a sudden. Following a search through the internet, I was able to find out using the remote control that the error code was E7. The E7 error code corresponds to a malfunction of the outdoor unit fan motor. How can I fix this?
Any help would be much appreciated.
