Advice? My old gas range has one of four electric spark igniters on the fritz. It sparks only faintly, only sometimes, but it will spark fully when I also turn anothr of the four igniters to the "lite" setting. Ineffiecient and concerning. I cleaned the igniter points and also the burn caps that they spark against. No improvement (maybe very, very slight but totally insufficient improvement).
Following instructions from Frigidaire I began to disassemble the cook top to inspect wires and connections beneath. I got no further than this first roughly 6 mm aluminum bolt. It snapped right away.
Thoughts how to proceed?
