I haven't fooled around with an oil burner in many
years. But back then, if the flame sensor tripped it,
the thing would require a manual reset to get it to
try to restart. Which the OP isn't reporting. Sounds
like it restarts again and again on it's own. Will new
ones do that? Seems unlikely because of safety
issue. You don't want it constantly pumping oil
in....
