Heya!
Heat stopped working on Sun dance Spa from '95, popped open the board to find some melted wires/board.
Had been using it for the past 6 months no problem, a few GFCI trips that had no explanation. Breaker panel at house is good so I assume when I hooked it up I didnt tighten the nuts/screws enough and with enough use they became loose and arcing occurred?
I have been checking and this is about as much information I can make a guess out of, any ideas on what went wrong and how to prevent in future if i replace the board?
two pics here, looks like hot coming in was melted and hot going out in addition to the bar above it
