I first tried to fix the SE error by resetting the ribbon cable that connects the circuit board to the panel by following instructions I found on youtube. That cable reset (removed, cleaned and reconnected)  fixed the error. About a week later same SE error. Decided to order just the panel. I did not order or need the circuit board. I found additional instructions on youtube and replaced the board in 10-15 minutes. It's been about 6 weeks and no issues.
