As spadoctor pointed out, these DSI units do not use a thermocouple to detect the flame. They run a very small current *through* the flame to detect it.

Any connection in the path can keep it from working, as can a bad electrode.
A thermocouple, on the other hand, generates a small voltage when heated, using dissimilar metals. Completely different in design and operation.
I stand corrected.
Sounds like DSI reinvented the wheel.
