James M Acworth , GA April 05, 2022 Appliance: KitchenAid Gas Cooktop KGCS105GSS2 On my KitchenAid rangetop all ignitors were constantly firing with all burners in the off position. I removed the grates and burner tops. Then took the screws out that held the burner spreaders. This allowed me to remove the range cover to expose the gas lines and wiring. The ignitor switches were sealed, so I could not test them individually. I ordered a new wiring harness with the new ignitor switches. These were in stock and arrived within two days. I replaced the wiring harness, put it all back together and it is working fine. Note: I ordered some new screws for the burners. Should have ordered all new screws. Broke one in the burner and could not remove it. This whole job took about four hours of elapsed job time over three days. Added benefit: Got to thoroughly clean the inner part of the range top. It is 20 years old. Read More... 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours Tools: Pliers, Screwdrivers
