what is error code f91 ?( panasonic invertor air-con)

gck, May 2010

If the gas was lost in installation and the air con was turned on and then shut down after 5 minutes then the f 91 code was found . The gas was replaced but the air con now will only run for 5 minutes then shuts down even with new gas installed and continues to do this every time why is this ,is it because the f91 code was locked in its memory right from the beginning.

Anche a me capita l'errore F91, in caldo funziona per 10 minuti e poi si ferma e lampeggia timer ? Hai poi risolto il tuo problema ?
