I have a ‘20 Magnitude SV34 and had some FireFly issues early on. The thermostats would call for cold and the circulating fans would run but the compressors would not. Or the compressors would start but the circulating fans would not run.
If I shut down the 12V to reboot the system, it would work normally for a bit but then the problem would occur again.
I contacted FireFly and we did some troubleshooting and ultimately they determined the G7 mainboard needed to be replaced. I documented everything and Thor had the dealer replace the board under warranty.
I have not had any issues since.
