If your gas stove won't light it's probably one of these 5 issues — here's how to fix them
Gas burner won't ignite? Troubleshoot the problem by following these steps

There's nothing quite like the frustration of being ready to cook dinner, turning the knob on your gas stove, and hearing that endless clicking sound with no flame to show for it. Your burner might be getting gas, the igniter might be sparking, but somehow the two just aren't connecting.
Before you start planning takeout for the week or calling an expensive repair technician, take a deep breath. Most gas stove ignition problems stem from simple issues that you might be able to diagnose and fix yourself.
The culprit is usually something mundane like food debris, a loose wire, or a worn-out igniter, and it's something you'll find on even the best gas ranges. Try these five troubleshooting tips if your gas stove is acting up.
1. Clean food debris from the burner assembly
Food spills, grease buildup, and cooking residue are the most common culprits behind ignition failures. Even small amounts of debris can block gas ports or prevent the igniter from sparking properly.
Start by removing the grate and burner cap from the problematic burner. Lift out the sealed burner base, which may require removing a few screws depending on your stove model. Clean all components with warm, soapy water, paying special attention to the small holes around the burner ring.
Use a toothbrush to clear any stubborn debris from the gas ports, and wipe down the igniter with a damp cloth.
2. Check for loose electrical connections
Vibrations from cooking, cleaning, or even normal use can cause electrical connections to work loose over time. Before inspecting any wiring, turn off the gas supply and unplug your stove or flip the circuit breaker.
Remove the burner components as described above, then look for any loose or disconnected wires near the igniter. These connections typically use simple plug-in connectors rather than permanent wiring.
Gently press any loose connections back together and ensure all wires are properly seated. A loose connection often causes intermittent problems where the burner works intermittently.
3. Test the igniter spark quality
A weak or discolored spark indicates a failing igniter that needs replacement. Turn off the lights in your kitchen and try to ignite the burner while watching the igniter carefully. A healthy igniter produces a bright blue-white spark that jumps consistently between the electrode and the burner.
If you see a weak yellow or orange spark, or if the spark seems intermittent, the igniter has likely worn out. This is normal wear after years of use, and replacement igniters are relatively inexpensive and widely available for most stove models.
4. Replace a faulty igniter
If cleaning and checking connections don't solve the problem, you likely need a new igniter. Turn off the gas and power to your stove, then remove the burner assembly. The igniter typically disconnects with a simple plug-in connector—no wire cutting required.
Use your stove's model number to order the correct replacement igniter online or from an appliance parts store. Installation is usually just the reverse of removal: plug in the new igniter, reinstall the burner assembly, and test the connection.
5. Verify proper burner cap alignment
Sometimes the simplest solutions are the most overlooked. If your burner cap isn't properly aligned after cleaning or maintenance, it can prevent proper gas flow and ignition. The cap should sit flat and centered on the burner base with no gaps or tilting.
Many burner caps have notches or tabs that must align with corresponding features on the burner base. If the cap rocks when you press on it or doesn't sit flush, remove it and reinstall it carefully, ensuring all alignment features match up correctly.
A misaligned cap can block gas flow or direct the flame improperly, causing ignition failures.
