I have a 10kw Generac M#0060611 with the 0H6680D Nexus controller. LPG fueled and I use as Prime power at an off grid camp. Been installed since 2012 and have had no issues and no bug or rodent problems in the enclosure.
We use it about 6 times per year so not a lot of hours on it. Recently it won’t start. Replaced battery but noted that I can’t go through the controller startup, buttons are non responsive. I am assuming that the controller is the problem but looking for confirmation. It’s 300 miles away so it’s not possible to check it readily. Thanks

So this isn't going to help much since it's so far away, but does the auto-off-manual switch work? If so, it might just be that the ribbon cable has come unplugged that connects the touchpad to the PCB inside. If that's the case, you can open the controller (with it completely disconnected) and re-connect the ribbon cable. Bring some tweezers to assist.

If not, I'd say the controller is toast...

Thank you for the response. The auto/manual switch did not work either. I believe the controller is dead too. Thanks
