Many gas range manufacturers have done away with using a pilot light to ignite the gas on surface burners in favour of spark electrodes. Spark electrodes are much safer than pilot lights, as the electrode doesn't rely on a small flame to remain lit at all times on the stove. Instead, the spark electrode gets an electrical current from the spark module, which is located in the range's control housing. The electrical current travels through the spark electrode, creating a spark that ignites the gas, lighting the burner. If the spark electrode fails, it won't create a spark and must be replaced.

Unplug the range from the wall outlet before beginning the repair.
Lift the burner grates and burner caps off each burner and set them aside.
Remove the screws securing the burner bases to the top of the range, then remove the burner bases. On some ranges, the burner bases may pull right off or may not require removal to remove the top.
Insert a putty knife between the bottom of the hob and the top of the range cabinet to release the spring clips securing the top to the cabinet. The clips are located near the front of the range on the sides, or on the sides of the front of the range, depending on the model.
Lift the hob and secure it using a sturdy object.
Remove the burner orifice containing the faulty electrode by removing the bolt securing it to the range.
Remove the screws securing the ignitor to the orifice, then remove the electrode.
Pull the wire connector off the terminal on the electrode, then discard the electrode.
Attach the wire connector to the terminal on the new electrode, then secure the electrode to the orifice using the screws that were removed.
Replace the orifice, using the bolt that was removed to secure it.
Lower the range top, then replace the burner bases, caps and grates.
Restore power to the range to complete the replacement.
Tips and warnings
- If the old wire connector doesn't fit the terminal on the new electrode, take the electrode to a hardware store to determine the correct size and buy a new connector. Cut the connector off the wire, just below the connector, then strip approximately 1/4 inch of insulation off the wire. Insert the wire into the end of the new connector, then crimp the connector to secure.
