I'm not sure that there's a good way to test that, but perhaps you know of one?
Continuous sparking is a BAD Circuit Board
Spark should stop when flame is proven
Of flame proving was NOT occurring circuit board would shut down gas valve regardless of sparking
Circuit board can be tested using a 'board tester' ---- some RV repair shops have them
More drying using haior dryer with circuit board disconnected and removed so both sides can be blown dry MIGHT improve function
New board and WET....end up with same issue...bad board
Relocate/lift board .....
