Well, if they don't repair their own buildings it's hard to believe they would offer replacement boards. That said, if you were willing to swap boards does this mean you can access/remove the existing board? If you post photos of the board I'm thinking we could come up with some troubleshooting suggestions on what to measure to effect a repair.
There have been a few OGR threads about the Menards building electronics. For example, in this thread for the Salt factory, some measurements helped to further the collective knowledge of how the Menards lighting electronics works (or not). After repeated grousing here on OGR, I notice that Menards now publishes the power requirements for some of their buildings - so now you can better select a suitable transformer!
