Thanks for the quick response. So once the board times and goes on MLT it should maintain a low signal on that MLT input until the power is cycled right? I do see on the print where the low oil switch is connected to the "z" pin on the dual timer board. This suggests that the MLT input does not need to be constant to force an MLT, it could MLT just from the low oil switch closing for a second. Does this sound right that the MLT input is self-sustaining if grounded momentarily?
