Check the small wires that connect between an igniter that didn't spark and the control module near the front of the burner compartment If a wire is detached, push the metal connector onto the tab at the igniter or module, and turn on that burner knob as before. If the igniter sparks and ignites the gas, the problem was a detached wire. Alternatively, if the wires are attached and the igniter doesn't spark, the igniter is faulty and has to be replaced. Proceed with troubleshooting igniters that spark but a burner doesn't ignite.
Tyler Lizenby/CNET Gas ranges certainly come with a handful of advantages, such as nearly instant heat, long-term cost savings and, of course, the ability to continue cooking when the power goes out. But unlike with coil-element or electric stoves, you have to ignite the burners to be able to cook anything on a gas stove. Fortunately, the problem is usually something you can resolve yourself. Learn why your gas stove won't ignite and how to fix it. Problem: It's clogged with food debris Whether it's grease buildup or food crumbs, one of the most common causes for a gas burner that has trouble igniting is debris blocking gas flow to the igniter. The fix: Begin by removing the grate covering the troubled burner.
Next, remove the burner cap, which should lift off with ease. The sealed burner base will either lift off or you may need to remove a couple screws before removing it. Clean the surrounding area with a warm, soapy wash cloth. Soak the sealed burner base in vinegar or warm water and use a stiff brush to remove any debris. Finally, clean any remaining debris out of the burner holes with a toothpick, sewing needle or compressed air.
Reinstall the burner, cover and the grill, and try igniting the burner once more. If this doesn't work, there could be a kink in the gas supply line or a larger issue, and you may want to consult a professional. Problem: There's a loose connection While there aren't a ton of moving parts on a stovetop, it is possible for connections to come loose, particularly during cleaning or installation. If the wires which connect the igniter to the control module aren't making a solid connection, you won't get the spark needed to properly ignite the burner. The fix: First, kill power to the appliance by unplugging it from the wall or flipping the breaker switch. Remove the grate and burner cap from the problematic burner.
