With serial 473623, your 1200LRIM is in the oldest range (it took the 633205 kit, now discontinued). The Dinosaur 6212XX replaces the power board for 1200s with serials below 8981136. Before you swap boards, make sure the electrode tip sits right in the flame and the burner is clean, because that's what the board uses to sense the flame.
