I get that the ll's limit switch is mounted up front and lower down while the lll's is mounted farther in and higher up, so I suppose it gets hotter where the lll's goes, and I suppose that is why it has a higher temp limit.
I can swap the ll's back in , since apparently that was not the problem, but what are the risks of leaving the lll's in? It will get hotter before it trips, but is that too dangerously hot for that location--up front and lower down, so that farther in it will get hotter than the 190 would allow if it were in place back up there?
