Megger all components individually, I’d say. These Lux boards don’t like damp/low ins.. take hairdryer or WD40 to motor. Also check them all as being within expected ranges of dc resistance. After that, wiggle some wires, and finally look for dry joints on board. It’s worth it if it saves investing in a board you may end up not using. Oh, hang on a minute, that’s an ewm1000 board? EMW then. Or try replacing the 12v relays. But damp is first thing.
