Things You'll Need
Gas stoves commonly have an electric ignition system. This ignition system provides a spark to the gas supply exiting from the burners. A small switch on the front of the oven, or the gas control panels themselves, activate the sparking ignition. If the system has bad wiring or a blown fuse, the oven will not light no matter how long you activate the ignition. Most ovens have fuses and ignition systems that are simple to access and repair.
Unplug your unit and turn off the gas supply at the saddle valve near the unit.
Lift up the hood of the oven. If you have sealed burners, the lid will not lift up. Locate the ignitors near the burners of the unit. Clean any gunk away from the ignitor using a toothbrush. Test the unit.
Pull the burner dials off the front of the unit if the ignitors won't work.
Remove the screws at the ends of the front cover, where the gas supply knobs are located, using a screwdriver, and remove the cover from the oven.
Slide the wires off the burner valve switches and pull them off the burner valve by sliding the switch forward. The switch will have wires attached to it. Loosen the screws holding down the wires of the burner valve. Pull out the wires carefully. Place the wires in a new switch. Slide the new switch onto the burner valve. Replace the knob, and turn on the gas supply and power. Ignite the burner.
Follow the switch wires into the oven if the new switch doesn't work. Locate the module box, which is usually 2 inches by 3 inches. Slide the wires out of the module terminal by pulling on the wire connectors. Remove the screws from the old module and pull the module out. Insert the wires into the new module, using the same wire orientation as before. Reassemble the oven. Turn on the electricity and gas, and turn on the burner.
