Turn off gas and unplug cooktop. Lift off the 3 grills. Lift off the cast iron and aluminum burner parts. Lift off the five control knobs, noting that the middle knob has a thicker stem.Find star bit that fits the machine screws around each burner. Start removing with the bit in a nut driver. If you have to use a 1/4 inch socket for some, try not to break or strip the screws or the bit. Apply heat with a propane torch if stuck hard. After that, lift stainless tray off. Lift out foil pad. Mine was the center burner igniter. Using two wrenches each side, disconnect gas lines from each side. Phillips head to disconnect plate from burner. The igniter is held in place with spring and clip. Unplug igniter wire from electronic box. I used a hemostat so as not to lose the spring clip .Spring can be removed at the plug end of the wire. A big allen key fits the one inch wide middle burner part - remove it. Now pull the old igniter out through the top of the burner. Use a small round file to make the igniter hole smoother and maybe slightly larger. Thread new igniter through hole, plug end first. Spring and clip on bottom are hard to get. Try not to lose the clip- It can spring off into space.Plug igniter wire into electronic box. I used an anti-seize compound on all threaded parts. Go carefully in reverse order . Plug in cooktop and turn on gas. test new igniter. Good luck
First step is to turn gas off to cook top and also disconnect power to the unit. Than using a crescent wrench disconnect the gas line going to the unit from the Regulator. Than again using the crescent wrench disconnect the regulator from the bottom of the unit. Next remove the nipple that connects the gas line to the regulator from the old unit. Apply new pipe dope to the threads and screw it into the new one and tighten down. Next install the regulator to the unit and install the gas line to the regulator. once done with the install you can now plug the unit in and turn on the gas. You are now ready to use the cook top again
