You want to look for the flame sensor and try cleaning it with a piece of emery cloth or scotchbrite, it looks like the one in the photo and should be located by the last burner and pointed into the flame path, clean the metal part of it off. let me know what it does after that,
No problem, I have to drop out for a while anyway so I'll pick up your replies later,
Sorry once again. I was called away and just now finished cleaning the flame sensor as you suggested. The unit started up when I finished. I'll need to see if it successfully cycles the next few times. In the past it would cycle successfully after being shut off for an hour or so. There was a little corrosion on the sensor, so I cleaned it off. I'll keep you posted.
Just let me know,
Thats good news,
