Unplug the range unit from the wall socket. Turn off gas if shut-off valve for oven (below the oven) is not closing for whatever reason.
Remove baking dish tray from the bottom of the unit.
Unscrew the plate in front of the gas/electronic components to the rear beneath the oven.
Look for two white wires going up to the oven above and unplug them as needed below. Also, remove any ceramic caps splicing the igniter wires to the wires below. Keep the portion of wire left on the bottom for reattachment later.
Open the oven and remove the drip tray and flame spreaders by removing any screws as needed.
If needed to access the screws holding the igniter in place, dismount the burner by removing necessary screws. Burner can be pulled up and out of the oven and shut-off valve below should keep the gas from leaking out.
Dismount the igniter unit by removing any necessary screws.
Igniter unit should now pull straight up and out with wires in tow. By testing the igniter with a multimeter for resistance (200-Ohm setting), you can verify that the igniter has burned out (no reading). Your new igniter should read about 75 Ohms on the same setting.
Mount the new igniter to the burner as needed and place the burner back in place as needed.
Run the wires for the igniter back down below as you mount the igniter.
Use ceramic caps--new ones are provided in your igniter kit--to splice the wires from the igniter to the wires down below the oven. Do not twist the wires together. Merely place them in contact and use the ceramic caps to provide the twist. A wire cutter may be needed to clean up the wires for better splicing.
Plug the wires back into the electronics below as needed.
Plug your range unit back into the wall socket and attempt to start the oven.
If the igniter can be seen to glow and flames are produced, your oven is working. Turn off the heat and replace the flame spreader and drip tray. Replace the plate that protects the parts below the oven and your baking dish drawer.
