You'll find a site on the web by Al Luce. Stay away from this guy - he's all hype and no action. He advertises parts for all monitors, but when you go looking for parts you're re-directed to another page on his site with no parts to be found.
A typical cycle for a monitor is an air purge, then fuel and ignition. with a flame detected the solenoid pump goes into high and so does the flame. After a delay a klixon detects the plenum heat and turns on the fan - lo or hi speed. The flame rod must sense ionized air in the burner pot and complete its circuit or the unit goes into a lockout condition, then resets.
