honestly, like sub-zero in fridges, they are simple in many aspects compared to say GE or Jen-Aire. I*t's just some things that make you say "wtf?". Like the right bank of burners have an extra low simmer control. So the knobs have a potentiometer instead of the spark switch the other burners have. This POT switch goes to the simmer control which is tied into the spark controller and also it goes to a secondary solenoid.
Only three parts can cause a no light scenario, the spark module, the pot switch or the solenoid valve.
I'm getting spark, but not power to the solenoids. So I am going to change the pot switches first ($50 for both) then if that doesn't work I have solenoids in stock (found that the Bosch ones work) But I am not sure if I want to get the Simmer control first. It costs around $125.
