Yep, those two relays fail all the time! You can see spark inside them when the contactors pick or releases. Definitely a design issue.
No need to mention all the 120volt inputs. They also fail all the time causing to get redundancy error, which requires changing the main board and re-learning the shaft which is a pain. I hate seeing “syncing” message and all the delays for doing a simple task. it seems like they also know about all these issues and instead of solving the problem they have chosen to increase the warranty period to 5 years! I am not a fan of that.
I agree with you about Virginia Controls and MCE. Those are my favorite controllers too.
