I purchased a 2022 231RD in March of 2023. The day before our "maiden voyage" we noticed a red fault light on the solar controller and that it was no longer charging the battery. The Furrion charge controller manual says that a red light is a fault. After our trip we took the trailer to the authorized repair shop at the place we purchased the trailer. They worked on it for a week and thought they had solved the problem. However the unit still showed a steady red light. The repair shop then turned in a warranty claim to replace the unit. They did that last week. However, the new unit still shows a red light. They have asked for a few more days to resolve the problem.
I suspect two things. One, there is some other problem with the wiring. And two, this repair shop does not have experience with these controllers, even though is is an authorized Grand Design repair shop.
I am guessing this unit has a wiring problem that originates from the manufacturer.
Does anyone have any suggestions? I don't see many people reporting this problem on this forum.
See attached picture of the error light.
