Then see what happens and if fixes your problem.

I had a similar problem with the A/C units in my 2020 Magnitude. Rebooting the system by shutting down the 12V would fix the problem... but only temporarily.

Eventually I had to have the G7a control board replaced. I spent time on the phone troubleshooting with FireFly and ultimately they determined that it was likely a bad control board.

It was under warranty so they required me to have a dealer replace it under warranty. If it wasn't under warranty, I think they would have sent me the part to replace it myself. The new G7a board fixed my problem.
Did what Judge suggested and it seems to be working. Thanks for all the feedback. Stay tuned....
