I was able to stop the IGBT overheating fault by turning the fan control from eco to standard, but this doesn’t really fix the main issue. Why is the fan not switching on when in eco mode? Is there a setting that I’m missing in the set up.

My first feeling is to say the IGBT was heating rapidly and the drive thermal state has no time to follow this fast overheating. In this case on ECO mode, the fan has no time to start and the IGBT overheating occured. The standard mode allow to take this in acount avoiding fault detection (because fault has no time to come).
