My Norcold 663 (1991) will not relite on propane. Works great on 12V or 110V.
3 years ago I replaced the eyebrow, cable to control board and the control board. It used to spark multiple times. Now it only gives the occasional spark. It will usually restart if I move the thermostat to warm and then to cold once it is up and running. It refuses to restart if left alone overnight. I replaces the ignitor cable (spark sensor) and burner. Suggestions as to what to check next? Thanks, Brad
