Ignitor switch harness GE cooktop with downdraft

[naftalik]

I am in the process of repairing a GE profile 30" gas cooktop with downdraft, One burner out of the 4 ( each module includes 2 burners) will not light up ( upper left burner). I have switched sides, the burner of the left module  works on the right side. After trouble shooting the wiring system i have isolated a faulty  ignitor  switch. My question is that i don't understand fully the function of the ignitor switch harness assembly ( There 6 total, 2 on the two right knob stems and 4 on the left two knob stems, the left  four are stocked 2 and 2 on each stem ). is there a service manual for the GE gas cooktop?

Hi

It would be helpful if you could post the model number for us, thanks.

The GE cooktop model is JGP990. The ignotor part # WB28X10100

Sorry, the ignitor Assembly part # is WB24X10143

The two extra switches operate the blower so it will turn on when using the grill. That sure is an expensive harness. I checked for a generic replacement with no luck.
