Future reference for Suburban troubleshooting

My NT24SP worked fine on the bench but was erratic in the trailer. The firing sequence always started, but actual firing of the igniter was a random thing. Finally found a crack on the back side of the circuit board that broke a couple of the pathways. It was hard to tell if it was really a crack until I flexed the board a little, and then it was obvious. Hope this helps someone in the future.

Hi, I almost skipped over this thread because I thought you were talking about a Chevrolet / GMC Suburban. Anyway, good information to know.
