OK, another issue with my now old Thermador (15+ yrs). Out of the blue neither of the extra low (sequenced) burners will light. In this case neither burner's solenoid clicks when turning gas knob to start or any other position. Seems like no power is getting to both solenoids. The 2 simple burners work fine as does the oven. I'm at work, so can't check until tonight at the earliest.
Seems odd that both switches at the gas valves would fail simulaneously and one of the solenoids was replaced about a year back (found you can buy just the electric portion and replace). Guessing the simmer controller fried itself or maybe a ground issue or maybe who knows?
Anyone seen this before with these Thermador units?
Although the extra low simmer thing on these units is great, over the years I've found it a bit problematic with the erratic spark module.
As always, thanks in advance.
