Dometic RM8501 - No Ignition in LP Mode

Hello All,
I have a Dometic RM 8501. Auto Ignitor is not working (LP mode). I heard a few irregular, slow clicks in the space of about 15-30 seconds, then no more after that.
It goes through the cycles then faults out. But there is NO sparking, or attempt to spark. Also, I cannot light it manually while cycling. I already checked fuses, checked / cleaned ground connections, cleaned burner parts and replaced the burner control unit. Next, I guess, is the main control board. It worked great for the few years I've owned it. Works fine in the other two modes.
Hoping someone has an idea or two before spending $250 on a control board.
Thanks,
Ken
