I have a Suburban NT-12S with a module board I believe is kaput. Everything appears to work except I only get 60V AC at the electrode instead of 6,000V to generate a spark. I would like to discuss getting your board. Otherwise, I too may retire the heater.

I trashed the heater (too much heat and battery
I put in $200 for repair & part 4 years ago and never used the heater.
Tested it & worked good. Cannibalized the module board for anyone that needs it.
