All 4 ignators are spaking with the contrtols on off position on my GE JGP328 cook top

For the GE JGP 328CEC2CC, I think it's the Switch Harness, GE Part #323. GE technician will come to your house and tell you that for a $80 diagnoistic fee. If he has the part, I guess two hours labor maybe $120, and the part around $40. The stove top has to be disconnected from the Gas and taken out. I think you're looking around $300 on this fix. In the mean time, buy a long handle Bic lighter, pull the electric plug, turn the lighter on first and Gas knob to Lite. Wallaa - It works! I don't think GE products are made to last more than five years. For the GE JGP 328CEC2CC, I think it's the Switch Harness, GE Part #323.
