Question weak/no sparking - Thermador gas professional (unsealed) cook top

Gas flows (I can light any burner with a match).

However, one burner row (both front and back) won't spark. The other row sparks (albeit weakly). Curiously, I cleaned the area near the ignitor and cured the original problem.

However, a week later, burners on the other row stopped sparking - either no "clicks" from the ignitor or a single click. It "feels" like a cleaning issue (the ignitor area is heavily corroded, so a ground may be failing) but it may be something more substantive. I tried simply jiggling the ignition wire when cleaning the area with no effect. This is a vintage 1990's Thermadore which has been heavily used, so perhaps its time has come after 20 years.

It would be nice if a girl (me) could restore this thing.

Welcome to the forums.

It's either a problem with shorting igniter electrodes or a defective spark module.
There are several different spark modules used in the Thermadors and are based on model number.
