Victron Inverter Fan Running

[Dino]

Hi, I called out to my boat today and the Victron Atlas 12v 1600w inverter fan was running continuously. The inverter was switched off on the on/off/standby switch. I tried turning it on and off a few times but it wouldn’t turn off. The shore power is plugged in for the winter.
Any ideas how i can get this to turn off?

Remove the fuse.
