It wouldn't light when it got in the teens because it couldn't draw enough DC power to open the sail switch. Between a new circuit board and a new converter it has worked fine. I know about the half sleeping with one ear cocked to hear the furnace ignite.
Glad someone else has experienced that - we put in a new sail switch - in fact the only original things in the furnace is the ignitor, circuit board, & burner. It's been out and on the work bench 15 times......I'm not ready to turn it into a piece of yard sculpture.....
At least we're going to have a break in the weather -
