Dometic RM2652 no power to upper control board

Jim, Just to be clear. I did hear the ignitor snapping/pulsing with the ignitor plugged in and also with it unplugged. On the last part of your last post when you said (If you have 0 ohms on the igniter wire to the electrode and the screw that retains the cerramic tip is tight, and do not hear the snapping then the wire has a short somewhere there at the screw.) Is the snapping you are talking about at the electrode(spark)? Not pulsing at the ignitor. Thanks
